Breaking News: The 5 Percenters May Not Receive All of Their Water Allocation

5 Percenters and Endangered Fish May Both Lose

By Patrick Cavanaugh, Farm News Director

Will the 5 Percenters—the Federal water users in California who were restricted by a 95% water allocation reduction this year—actually receive the promised 5% allocation? This scenario follows a more-than-average winter rainfall and snowfall throughout the state.

Ryan Jacobsen, executive director and CEO of the Fresno County Farm Bureau, said, “arguably it’s turned out to be much worse. Right now, for the initial 5% allocation to even be questionable right now is just absolutely insane. It all boils down to the amount of water being held up in Lake Shasta for fish purposes, which has put a major stranglehold on what’s happening down here at this point,” noted Jacobsen.

Central Valley Project (CVP) Water

At Shasta Reservoir, a keystone reservoir of the Central Valley Project, the U.S. Bureau of Reclamation essentially discharged flood releases earlier this year just to make room for the water that was expected to come in. Shasta now stands at a above average full for this time of year, because the Feds are holding all the water for release for salmon later.

This is part of the plan to have cold water available to release for the salmon. And Shasta actually has 30 percent more cold water than what they thought, and water leaders are pushing hard to get the Feds to release it for agriculture.

San Luis Reservoir at Dead Pool Status

And San Luis Reservoir is at a dead-pool status, which insures no more water can be sent south from that reservoir. Dead pool means no more water can be drawn from San Luis Reservoir, which does not bode well.

Jacobsen said, “This means our federal contractors’ 5% is in question. And that’s the irony: we were looking at such a strong year—or at least an average year [of precipitation]—and ending up now where our meager water supply is in jeopardy. This is incomprehensible and inexcusable from the federal side.”

Shasta has both federal and state water, and the federal side is essentially nothing at this point, explained Jacobsen. “Farmers rely upon San Luis Reservoir water for July and August irrigation, “and the water is essentially gone at this point,” he said. “It just shows you the major mismanagement we’re seeing from the federal side and the inability to capture water even when it is available, and not at the demise of any of these species.”

Jacobsen reiterated, “Back when the precipitation was falling [last winter], water was available at some extraordinarily high levels; yet, we never saw the increase in pumping that we would have expected under the normal conditions. “Of course, we’ve seen less pumping this year for the farmers and the cities south of the Delta,” noted Jacobsen. “During the times of the rainfall this year, it was essentially excuse, after excuse, after excuse. Some newer excuses pertained to why the pumps were not operating or operating at a very reduced capacity,” explained Jacobsen.

“The situation has been frustrating for a couple of years, but the anger continues to build because right now, this is not a ‘Mother Nature’ issue. It is completely a man-made regulatory drought that is, again, just incompetency at its best.”

“When we talk about the water stored behind Shasta [Dam] right now, really it is for the fish,” noted Jacobsen. “The most-watched fishery, at this point, is the salmon fishery. We’re in year four of this drought, but when it comes to the critical side of fish, the salmon essentially operates in three-year cycles. The last two years have been arguably two of the worst years on record for them, and this potential third year is a kind of make-it-or-break-it for salmon fisheries in the Delta region.”

Unfortunately, per Jacobsen, many decisions have been based on guesstimates. “There are a lot of folks who think we need to reserve all of this cold water for a fishery that may or may not be responding to what has been done in the past for this [contracted irrigation] water that has been given up for those purposes,” Jacobsen explained. “Right now, I think we’re doing a lot of experiments at the cost of jobs and employment, and most importantly, the farms here in the San Joaquin Valley. The frustration is that science is really not playing a big part in it. A lot of decisions are just simply, ‘We think we should be doing this versus what the science actually says we should be doing.’”

Jacobsen’s leading frustration is that all that water taken from farmers and given to fish has not helped the fish at all. In fact, the smelt and salmon numbers continue to decline. “I talk about growing frustration and anger from so many folks in the last couple of years… specifically because it hasn’t made a difference,” said Jacobsen. “An exorbitant amount of water has been given up for these fisheries, [endangered fish populations] continue to decline and crash, and as we’ve been saying for years, it is beyond time to look at just the water exporters,” he added.

Jacobsen maintains other stressors should be seriously investigated. “Many other issues taken place in the Delta should be pulled into play here, but again the regulators and the environmentalists continue to look only at the exporters as the sole issue for fish decline. There are so many other factors out there that need to be looked at,” he said.

Duarte Nursery v. U.S. Army Corps of Engineers Update

PLF Attorney Reports Duarte Appeals Court Decision—Once Again

By Patrick Cavanaugh, Farm News Director

Damien Schiff, principal attorney at Pacific Legal Foundation (PLF) who has been representing the Duarte family in their legal battle with the U. S. Army Corps of Engineers (Corps), provided this update after Judge Kimberly J. Mueller, U.S. District Court for the Eastern District of California dismissed their summary judgment motions on June 10, 2016, and ruled the Corps’ February 23, 2013 cease and desist order did not deprive Duarte of liberty or property. Schiff said his client’s next course of action is filing for an appeal of the judgment.

“It’s disappointing, in particular, because earlier in the case, we had received a very favorable decision from U.S. District Judge Lawrence K. Karlton, the original Federal Judge assigned to our case who ruled in our favor on our due process challenge to the Army Corps’ cease and desist order.” Judge Karlton retired from the bench in 2014 and passed away in 2015. “It was particularly disappointing to see Judge Mueller reverse Judge Karlton’s decision.”

“Launching the appeals process will take some time,” Schiff explained. “Unfortunately, the case is complicated because there are a lot of claims going on and not all of them have been resolved by Judge Mueller’s decisions. The general rule in Federal Court is that you cannot appeal until a final decision has been made that decides all the claims against all the parties.”

Damien M. Schiff, Principal Attorney, Pacific Legal Foundation’s National Litigation Center

Considering the preponderance of hills and valleys across the United States, the magnitude of this case has growers—not just from California, but nationwide—concerned about the outcome and precedents resulting from this case, as well as the significance of future Army Corps-issued cease and assist orders. “It is an amazing assertion of power by the United States Environmental Protection Agency (EPA) and the Corps,” Schiff said, “and I think that’s why we see not just farming groups and property rights groups, but also a majority of the states, challenging the Agency’s Waters of the U.S. (WOTUS) Rule.”

A significant point of contention in the case, Schiff explained, stems from Judge Mueller’s ruling that because the Duarte property had not seen any farming activity since 1998, the Clean Water Act’s farming exemption was no longer applicable. “That’s, in part, why we challenged the cease and assist orders,” said Schiff, “because the Corps issued this directive without giving any prior notice, much less any opportunity to present contrary information. The reality is, this property, and the other properties in the entire area, have traditionally been used for agriculture, and are, in fact, zoned for agricultural use.”

The Duarte case is so multifaceted,” Schiff said. “The land was always agricultural, and what was done on the property is consistent with normal agricultural farming practices; there is really nothing exceptional about what went on. What’s particularly problematic for the Corps here is that Duarte went above and beyond the call of duty by having a wetlands consultant ensure that all of the areas assessed to have vernal pool or wetlands characteristics were marked and avoided entirely.”

Whatever the outcome, the Duarte case will have far reaching effects on legal precedent throughout the agricultural community as well as on the cease and assist orders issued by the Army Corps to families throughout the country. “Surprisingly, there isn’t very much case law on what process, if any, is owed to the landowner before the agency issues these orders,” Schiff remarked. “However the Duarte case ends up, I think that will have to be litigated in other parts of the country.”

WGA Conflicted on SCOTUS DACA Decision

Western Growers Association has Mixed Feelings on Recent Supreme Court DACA Decision

By Patrick Cavanaugh, Farm News Director

The 4-4 ruling on immigration reform last month by the Supreme Court of the United State’s (SCOTUS) affirmed the lower court’s injunction against President Obama’s executive order, which would have granted deportation deferrals and temporary legal work status to about five million undocumented immigrants. Tom Nassif, president and CEO of Western Growers Association (WGA), has been vocal about the need to establish some type of immigration reform.

Nassif compared the recent SCOTUS ruling to what happened when a 2013 U.S. Senate-endorsed bill that supported a pathway to citizenship was never passed in the U.S. House of Representatives. “The House did not want a pathway to citizenship,” said Nassif. “They were not even sure if they wanted a pathway to legalization. Most Republicans did not even want a border security bill in the House coming to the floor for a vote because they didn’t want any immigration reform—whatsoever.”

Nassif said, “The House was part of that Send-them-home! crowd that considered anything you did—even if it was putting them on probation—as amnesty. It is interesting that with the House doing nothing about immigration, what we have today is amnesty, because we’re not doing anything about it.”

Nassif expressed mixed feelings about the SCOTUS decision. “In a way, it disappointed us; in a way, it didn’t. It didn’t disappoint us because there was no requirement that people working in agriculture who might qualify for this Deferred Action For Childhood Arrivals (DACA) or Deferred Action for Parents of Americans (DAPA) would actually remain working in agriculture.”

To get a pathway under the Senate bill, farmworkers would have to stay in agriculture for a certain number of years, but they could eventually work in other industries. So if you have a choice of working in any industry, why would you go to work on the farm? But, in this instance, you would adversely affect other American jobs,” said Nassif.

Nassif said the motivation of the Obama administration is understandable due to the inability of Congress to compromise on immigration reform, yet Nassif maintains the Immigration Reform should not be done with Executive Orders as the President has done. Instead, Nassif stressed that Congress should take up Immigration Reform and pass it.

It Is California Cantaloupe Week!

California Cantaloupe Week Begins in Fresno County

By Lauren Dutra, NAFB Summer Intern

Established by the Fresno County Board of Supervisors for this week, Monday July 25 through Sunday, July 31,“California Cantaloupe Week,” recognizes Fresno County as the lead canteloupe-producing county in California, which currently produces 75% of all cantaloupes sold in the United States.

Steve Patricio, president and CEO of Westside Produce, a grower, packer and shipper in Firebaugh said, “The quality has been absolutely outstanding this year, with some of the highest sugar results we’ve seen in recent years.” Patricio has also observed great demand in the marketplace as well. At this point, it’s time to eat those beautiful California cantaloupes,” he noted.

Packed with nutrition, “Cantaloupes are one of the most outstanding things we can eat for our health,” Patricio affirmed. “That daily dose of cantaloupe can do wonders for a healthy lifestyle.”

The California Cantaloupe industry has been on the forefront of the food safety movement throughout the world, “You can be assured that every cantaloupe grown, packed and shipped from California meets the highest standard of food safety anywhere in the world,” Patricio stated.

The California Cantaloupe Advisory Board (CCAB) requires all California cantaloupe growers, packing operations, and cooling facilities undergo mandatory announced and unannounced government food safety audits. The audits are based on a set of food safety standards developed from 20 years of university research along with input from government, food safety and farming experts. CCAB food safety systems allow for science-based standards to be updated as new information or science becomes available.

You can review all of the safety checkpoints here.

Breaking News: Cal Poly Opens New Greenhouse and Insect Rearing Facility

New Greenhouse Facility Opens to Save Citrus from Psyllids that Vector HLB

Facility to Rear Tamarixia Radiata, Natural ACP Predator

By Patrick Cavanaugh, Farm News Director

Scores of citrus industry leaders, citrus growers, scientists and CDFA officials attended the ribbon cutting event TODAY at the opening of a new greenhouse on the Cal Poly Pomona campus to rear Tamarixia radiata, a tiny parasitic wasp imported from Pakistan because it is an Asian Citrus Psyllid (ACP) nymph predator. ACP, in turn, is a serious nonnative citrus pest that can vector Huanglongbing (HLB)—a deadly citrus disease also known as Citrus Greening—that has devastated the powerhouse citrus

industry in Florida, threatens to ruin additional citrus economies, and is the biggest threat the California citrus industry has ever faced.

According to the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS), infected citrus trees “produce fruits that are green, misshapen and bitter, unsuitable for sale as fresh fruit or for juice. Most infected trees die within a few years.” ACPs have been detected in Alabama, American Samoa, Arizona, California, Florida, Georgia, Guam, Hawaii, Louisiana, Mississippi, Northern Mariana Islands, Puerto Rico, South Carolina, Texas and the U.S. Virgin Islands. Of those locations, the HLB disease has been detected in California, Florida, Georgia, Louisiana, Puerto Rico, South Carolina, Texas and the U.S. Virgin Islands.

ENTER: Tamarixia radiata

Use of the ACP predator, Tamarixia radiata as a biological control for ACP was discovered by Mark Hoddle, biological control specialist and principal investigator, UC Riverside ( UCR), Department of Entomology. The first release of Tamarixia was in December 2011 after USDA-APHIS cleared the natural enemy for release from the Quarantine Facility at UCR.

Mark Hoddle UC Riverside Department of Entomology

“Tamarixia can kill ACP nymphs in two different ways,” explained Nick Hill, a Tulare County citrus producer and Citrus Pest & Disease Prevention Program (CPDPC) chair. “The first is parasitism. In this instance, a female parasitoid lays an egg underneath a fourth or fifth instar—the larger and final developmental stage of the ACP nymph before becoming an adult—nymphs that are most preferred by Tamarixia for parasitism. When the egg hatches, the Tamarixia larva begins to feed on the under-surface of the ACP nymph. Eventually the larva completely excavates the body cavity of the ACP nymph and pupates inside the empty shell of its host.”

Hill explained the first releases of the tiny and harmless wasp will occur this fall in urban areas, “to help control ACP so that we do not have to do mitigations such as spraying in those areas. We hope to get to a point where we no longer need to go into people’s yards and ask if we can treat the trees.”

“The issue,” commented Valerie Melano, professor and chair, Cal Poly Pomona Plant Sciences and interim chair, Cal Poly Agribusiness & Food Industry Management/Agricultural Science, “is that we need to come up with the best possible ways to raise enough wasps for big releases to prey on ACP. We will have CDFA employees working in this green house, as well as student workers who have participated in our research program all along,” noted Melano.

Hill added, “The idea is to get enough Tamarixia out there so they start reproducing themselves and they become self sufficient. This is tough to accomplish, but researchers think if they can get big numbers of the wasp into the urban areas, they can put a big dent in lowering the populations of ACP.”

Cal Poly Pomona Greenhouse

The new Cal Poly 5,040-square-foot research greenhouse, built in collaboration with Citrus Research Board and constructed through a $400,000 grant from the Citrus Pest & Disease Prevention Program, will house the second Tamarixia production program in California. CDFA’s Mount Roubideaux facility in Riverside houses current production. Both facilities will support the CPDPC biological control program that oversees releases in urban areas with high ACP populations.

The new greenhouse should produce a 1-1.5 million wasps. “It’s a very nice facility,” said Hill. “We are trying to boost the biological control program to produce four million Tamarixia a year.”

California Quarantine

The California Department of Food and Agriculture (CDFA) operates an extensive monitoring program to track the distribution of the insect and disease in both residential areas and commercial citrus groves. Results have determined quarantine zones, guided releases of biological control agents, and prioritized areas for a residential chemical control program. Nearly all of southern California is under quarantine for ACP, due to the fact that more than 15 residential trees have been discovered to be in infected with HLB.

The ACP quarantine in California includes parts of the following counties: Fresno, Kern, Kings, Madera, Monterey, San Benito, San Joaquin, San Luis Obispo, San Mateo, Santa Clara, and Stanislaus; and the following entire counties: Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare County, and Ventura.

Poultry Industry Doing Well, for Now

Poultry Industry Shines, Like a Canary in a Coal Mine

By Patrick Cavanaugh, Farm News Director

Bill Mattos, president of the California Poultry Federation, based in Modesto, reported the state’s poultry industry is doing well despite new regulations and wage increases. “First of all,” he explained, “it looks like chicken has taken over as the [category of] highest meat consumption now in the United States. It’s getting more and more popular, so that’s good,” Mattos noted.

“Also, the best thing is the industry seems to be weathering the Highly Pathogenic Avian Flu (HPAI) A (H5N1) storm,” he continued. “In California, we’re doing our due diligence with biosecurity. We don’t have any Avian Influenza. We’ll knock on wood for that.”

“The industry is also enjoying lower feed costs. That’s 60% of our cost, so that’s good news,” he added.

And, poultry industry employees have job security. “It doesn’t look like there will be fewer employees in the industry over the next few years, and we’d like to have more,” he said.

Notwithstanding the good news, challenges loom on the near horizon. “The Air Quality and Water Quality Control Boards are regulating a lot of different industries,” Mattos observed. “They’re starting to look at the poultry industry now that they have completed the dairy rules. We’re very concerned about those issues, so we are trying to work with the boards to explain to them what we do and how our business runs,” noted Mattos.

The updated minimum wage requirement may hurt the California poultry industry, another big concern of Mattos. “We supply half the chicken consumed in California. The other half comes from out of state. Without the same minimum wage requirements, we’re going to be at a disadvantage. We’re looking into the different possibilities—what we can do—to offset that.”

“You will be seeing some new things coming out from the poultry industry as we look at the ramifications of the new minimum wage,” explained Mattos. “We can’t compete with that. They are going to be taking a lot more percentage away from us, which may cost us some jobs if we don’t work this out.”

“With the minimum wage hike, California lawmakers are trying to appease workers. But it really affects businesses. Ours happen to be mostly in the Central Valley, which is the hardest-pressed area for unemployment. It isn’t a good place to have to follow wage requirements like you’re seeing in San Francisco and Los Angeles. It frankly makes no sense in the Central Valley,” said Mattos.

Pushing for Immigration Reform

The Unrelenting Push for Immigration Reform

By Laurie Greene, Editor

Tom Nassif, president and CEO of Western Growers Association is frustrated with the lack of immigration reform. “In 2013, we finally got a bill passed in the United States Senate. The reason we got it passed in the Senate is because we supported the pathway to citizenship; the other things we could work out,” Nassif said.

Tom Nassif, president and CEO of Western Growers Association

“However, in the United States House of Representatives,” Nassif continued, “they didn’t want a pathway to citizenship. They weren’t even sure if they wanted a pathway to legalization,” he noted.

“Most people didn’t even want a border security bill coming to the floor for a vote in the House because they didn’t want any immigration reform—whatsoever,” said Nassif. “They were part of that ‘send them home crowd.’ Anything you did, even if it was putting them on probation or fining them—whatever we did—was still considered amnesty. That is not amnesty. What we have today is amnesty because we’re not doing anything about it,” he argued.

Nassif had a mixed opinion on the recent Supreme Court of the United States’ 4-4 ruling against President Obama regarding his expansion of the Deferred Action for Childhood Arrivals (DACA) and Deferred Action for Parents of Americans and Lawful Permanent Residents (DAPA). “In a way, it disappointed us; in a way, it didn’t,” Nassif commented.

“The reason it didn’t disappoint us is because there was no requirement that the people working in agriculture who might qualify for DACA or DAPA would remain in agriculture. Under the Senate bill, to get a pathway, you had to stay in agriculture for a certain number of years. In this case, they could have gone to work in any industry. If you have the choice of working in industry, why would you work on the farm? The choice adds adversity and affects other American jobs,” said Nassif.

Immigration reform should not be done by executive order, according to Nassif, as President Obama was trying to do. “It should be done by the legislature. They have the responsibility and the duty to pass immigration reform,” he said.

Lt. Governor Newsom Supports Calif. Agriculture

Calif. Lt. Governor Newsom Says Ag is at a Hinge-Moment in History

By Patrick Cavanaugh, Farm News Director

In an exclusive interview with Gavin Newsom, Lieutenant Governor of California, during the recent Forbes AgTech Summit in Salinas, Newsom declared, “It’s interesting about California—outside of Hollywood—no two more iconic industries exist than Silicon Valley’s technology, and the agricultural industry.

“It seems self-evident to everybody here that we have a unique opportunity to collaborate,” Newsom said about the event which joined the Silicon Valley high tech industry with the state’s farming industry to create digital solutions for agriculture. “We have the unique opportunity based on proximity and based on history. It is also a cultural opportunity as it relates to relationships that have been formed over the course of generations to begin to build bridges and connect some dots.”

Newsom said he believes in bottom-up inspiration, not top-down. “I don’t think you can sell down your vision from Sacramento. It’s about regions rising together and creating conditions for just these type of collaborations,” he said.

Newsom particularly appreciated comments about innovation. “I wrote a book, [“Citizenville”] and I’m not here to promote that book,” said Newsom, “but the whole idea was about platform thinking. The concept is the federal government, state government, and even local government cannot prescribe a federal, state or local pill for every problem,” he said.

“The point is,” he continued, “if we’re going to solve the big problems of the day, we have to create an environment—a platform—to engage folks like yourselves to deliver the applications, literally and figuratively, to solve big problems. It’s self-evident to anyone who lives here in California, that we’ve got some big problems.”

Citizenville, by Gavin Newsom

“We have regulatory challenges in this state, and I say this as a business person with many businesses. I have a sense of kindred connection in spirit to the entrepreneurial ways that are here today,” he commented. Owner of three wineries, several restaurants and hotels, Newsom stated, “I am in the Ag business, of sorts. My point is, we could do a lot better to make a point that [agriculture] matters and we care,” he said.

“At the same time,” he added, “Silicon Valley is center-tip of the spear—all the innovation and discovery, and the change in the way we live, work and play,” Newsom said.

“We’re here on a hinge-moment in history where we are going from something old to something new, a world of mobile, local, and social; and cloud and crowd. It’s a moment of anxiety for a lot of people, a moment of merger—the detonation of globalization and technology coming together. Again, there’s a lot of anxiety,” he noted.

Newsom suggested this is an opportune time to try to connect dots and address challenges, not just on the regulatory side and on the economic development side in this state, but also on the self-evident issues of water scarcity in this state. “You may have different opinions about climate change, global warming or violent disruption,” said Newsom, “but, as a guy who told me the other day up in Dutch Flat, Placer County, ‘I don’t care about all you folks from San Francisco talking about climate change, but something just ain’t right.’ Which is another way of describing a connection that things have changed,” Newsom explained.

Newsom said that kind of predictive nature, in terms of how we construct a water system for a world that no longer exists, and for a population that is twice the size; self-evidently, we have to do things differently. “We’ve got to be more creative and we’ve got to be more strategic,” he noted.

“It’s a long way of saying we are grateful for the work [California farmers] are doing. The goal for us in California is to make these conversations sustainable. ‘Not just situational and not just one annual conversation, but these are dialogs that must continue every day in this state,” Newsom said.

“I’m one of those people who believes in the combination of nature and technology, bringing cross-disciplines together,” Newsom said. “Cross-pollinating, literally and figuratively, ideas and people—values. “I think we have an incredible opportunity here in California, not just to survive in the agricultural industry but to truly thrive in a growing, competitive environment.”

RECYCLED WATER PROJECT FOR WATER STABILITY, PART 4

Recycled Water Project for Water Stability: Takes Shape, Part 4

By Brian German, Associate Editor and Broadcaster

As part of our ongoing coverage on the North Valley Regional Recycled Water Program (NVRRWP), we spoke with Anthea Hansen, general Manager of the Del Puerto Water District. Over the next few months the project will start to take shape following the U.S. Bureau of Reclamation signing the Record of Decision last month, the high level of cooperation taking place among all the different entities, and positive public response.

Hansen commented, “I can’t speak enough about our good experience thus far. The cities, partners and consultants on the project have come together to really advance this concept—which was all it was seven or eight years ago —into something that will become a reality.

When demands are low in the Del Puerto water district, specifically in the winter months, water deliveries can flow to storage facilities or the San Luis Reservoir for later usage when demand is high. While many areas have already been using recycled water for agricultural needs, the progress by the North Valley program has inspired some communities to improve their own water policies.

Recycled water has long been used in agriculture in other areas of the state, most notably the Salinas Valley and in the south, maybe a little bit up in the north in the winegrape country. The Del Puerto Water District currently relies on water delivered through the Central Valley Project, which had zero deliveries for the previous two years, and are only providing 5% this year. This new program has the potential to produce more than 30,000 acre-feet of water per year as soon as 2018.

NVRRWP map (Source: www.nvr-recycledwater.org/description.asp)

Among an estimated 100 recycled water projects in various stages of development throughout the state, Hansen stated, “For the Central Valley, I think this is definitely a big first. We received about 14 public comments on the joint environmental document. Of those 14, three or four were letters of support, and we received some broad support from the environmental community.

A project of this magnitude to deliver needed water stability could also be accomplished in other dedicated communities, according to Hansen. “We believe this project to be a model for other municipal and agricultural agencies in ways to regionally solve issues together, and hopefully, it will be a model for the nation.”

Anthea Hansen, general Manager of the Del Puerto Water District

“Hopefully,” said Hansen, “people are looking at this as a good example of ways to think outside the box and use available technology to solve problems locally and regionally, which is what we have been forced to do here on the Westside.

“With all the complexities of California’s plumbing,” explained Hansen, “it would be impossible for a small district like Del Puerto to really affect any of the big picture changes, but we certainly do have the ability to affect how we act locally and regionally. I also think the Central Valley has not historically been a magnet for a lot of assistance, programs or changes that work to our benefit, so we have to devise these for ourselves or we’ll be out be of business. I’m very thankful that the two cities—Modesto and Turlock—on the east side of the river in our county, were willing to work with us, and I think we have a good partnership going forward.”

The North Valley Regional Recycled Water Program (Phase 3) won the 2015 Excellence in Environmental Engineering and Science™ Competition – Honor Award – Planning from the American Academy of Environmental Engineers & Scientists.

Solving Central Valley Water Salinity

Mizuno on Water Salinity Solutions

By Laurie Greene, Editor

According to a Central Valley Salinity Alternatives for Long Term Sustainability (CV-SALTS) report, rising salt levels in the soil and groundwater threaten the potable water supply and agricultural productivity for the entire region. Walter Mizuno, longtime lecturer in mechanical engineering at Fresno State and director, Valley Industry Partnership for Cooperative Education (VIP) Program, researches increasing salinity conditions in Central Valley soil and groundwater, as well as methods of desalination.

Mizuno explained, “As the salt level rises, and if the soil salts aren’t leached out periodically, the ground becomes unsuitable for cultivating several crops. Growers either shift to high salt-tolerant crops or essentially idle that land.”

Central Valley salinity conditions are serious, according to Mizuno. “Growers have already taken a lot of land out of production on the Westside,” he said, “and they’ll continue to do that until the salt mitigation measures have been implemented. Essentially, we need to get back to where we can currently sustain the amount of farming we have with the type of water that we have.”

“We are looking at desalination of agricultural drainage water,” Mizuno stated. “We’re trying to reclaim water that’s suitable for even human consumption; but right now, we’re looking at reclaiming water that is suitable for Ag use through a desalination process called vapor compression distillation, which takes drainage water from the Ag fields, distills it to make it pure and recovers some of the salts on the backside.”

Mizuno explained salt recovery would enhance the economic viability of this project by eliminating the cost of trucking or disposing the resulting brine and by possibly converting it into a revenue stream. “We’re trying concentrate that brine to a point, using solar evaporation, where we can find other uses for the highly concentrated form or maybe even sell it to a chemical processing company. We are also focusing on minimizing the energy cost to distill the water, to make the process more efficient.”

“We’re trying to combine multiple technologies, using ion exchange as our front end process,” Mizuno explained, “to get rid of some of the hardness in the water. We get rid of calcium and magnesium in the water, which helps the distillation process and protects the equipment for a longer period of time before requiring cleaning or eventual replacement. We’re using the brine stream of the distillation process to actually regenerate, upfront, the ion exchange units—similar to a home water softener.”

Mizuno explained, “When you look at the reasons why desal isn’t used more often—just the cost of energy makes the cost of the water expensive. So, we do a lot of energy recovery. Just take the basic process of distillation in which you heat up the water solution, boil it off, and condense the residue. A lot of that water you use, or a lot of the energy used to boil off the water, is lost; so we recover the heat from that steam to save energy. In other words, we don’t discard that energy; we try to reuse it.”

“We have been conducting studies on some Westside ranches,” he continued, “with our pilot plant that processes only one thousand gallons per hour. A series of ditches on those ranches collect the drainage water to be purified. Now, we have moved everything back to the Fresno State Center for Irrigation Technology (CIT),” said Mizuno, “because we’re building a brand new redesigned unit, which should be operating by the end of this year.

“The second phase of the project,” Mizuno commented, “is to move the unit out to Panoche, and conduct field testing out there. We will evaluate the energy efficacy and also the economics of the unit and process, and we will field-test to determine how rugged and dependable it is out in the actual service area.”

“This is actually a research project,” Mizuno clarified. “We’re still fairly far away from commercializing it. Basically, we will evaluate the scalability of these units so that depending on the size of the farm and everything else, you can either put multiple units out there or design a single-unit system very similar to ours. You could size the system to meet whatever the demands are, but you need a reservoir or holding area, and you’d like to be able to operate 24/7.”

“We are considering using solar to power this,” Mizuno mentioned. “The issue with solar is, obviously, it tends to work during the daylight hours but doesn’t do much during the evening hours. We’re looking at using batteries, electricity, natural gas or some other energy source to keep the process running when the sun goes down, but it’s a matter of economics.”

Mizuno said the research team is optimistic about the process itself, but he does not anticipate it will be a cure-all. “It is a research project,” Mizuno reiterated, “and we’re trying to see if we can drop the energy cost, and lower the water cost. I think the economics will change though. Water will cost more for everybody in the next few years. As that changes, I think some of these technologies are going to become feasible from an economic standpoint.”

The entire state shoud be aware of these water issues, according to Mizuno. “I think there are still a lot of issues that the common person isn’t aware of and how they fit in, and Ag is no exception. I would like people to understand that we are working to stretch the available amount of water supplies we have and we are working on technologies that are yet unproven. But some of these technologies will require a few more years—to many years to solve. Others are not economically feasible today, but they may be in the future as water supplies get tighter.”

Mizuno has observed that farmers are already doing a lot to conserve water, particularly employing the use of new technologies such as drones to evaluate water stress and nutrient stress in plants. “Right now,” he offered, “we are looking at another piece of the puzzle; we’re trying to stretch the amount of water supply we have, utilize it in multiple-use scenarios, and use it more intelligently to make some waste streams into revenue streams.”

Mizuno urges the general population to just be aware. “Conservation is the first step for a lot of people,” he said. “That’s the easiest way to stretch water supplies, and so I think people need to understand that water is a finite resource in the state of California. The water situation is not likely to get better anytime soon, even if we have normal rainfall and so forth. We are in an overdraft situation with our water supply.”

CV-SALTS participants collaborate to develop a workable, comprehensive plan to address salinity, including nitrates, throughout the region in a comprehensive, consistent, and sustainable manner.
