BAKERSFIELD, Calif. – The aquifer and food crops in California's Central Valley may be tainted with chemicals from nearby oil fields, according to a new report.

Researchers from four institutions, including Lawrence Berkeley Labs, looked at 173 chemicals used in oil and gas production and found that more than 100 have been flagged in the federal chemical database for acute toxicity, biodegradability, and environmental persistence. Ten are considered carcinogenic or are suspected of causing cancer.

Patrick Sullivan, climate media specialist at the Center for Biological Diversity, said the waste water, also known as produced water, could be finding its way into the food and water supply.

"These oilfields are supplying produced water to irrigate crops and recharge underground aquifers that supply water for agriculture, but also for people to drink," he explained.

The California State Water Resources Control Board said water districts in the Central Valley have been distributing produced water for 30 years, and that they meet all water quality standards.

Maryam Barajas, public information officer for the board, noted that no study has shown health hazards from produced water, and no water from fracking is allowed on food crops.

However, Barajas added that the Central Valley Regional Water Quality Control Board has convened a Food Safety Panel to investigate. It has met twice but hasn't recommended any changes thus far.

"If the Food Safety Expert Panel comes back and recommends a moratorium on the use of produced water for irrigation, then the Central Valley Regional Water Board will no longer permit that process," she said.

The report alleges that oil companies are withholding information on 38 percent of the chemicals they admit to using, claiming that they are trade secrets.

Sullivan insists even the ones that are known aren't being monitored closely enough.

"Current water-testing procedures in these areas do not test for many of these chemicals," he added. "They just are not set up to do that."

The Cawelo Water District near Bakersfield disputes that claim, saying the district hired a toxicologist to monitor an additional 70 organic compounds, and found its water to be safe for agricultural use. The district also tested fruit and nuts raised with produced water and found their chemical composition to be no different than crops raised on other water supplies.

The chair of the Federal Trade Commission will be in rural Iowa this weekend to hear from farmers and other residents about the proposed sale of Iowa Fertilizer to Koch Industries.

The sale is pending FTC approval. Iowa spent $500 million to build an Iowa Fertilizer factory in Weverly to create competition in an already consolidated industry.

Aaron Lehman, president of the Iowa Farmers Union, said he plans to tell FTC Chair Linda Khan a sale to Koch Industries would backtrack on any competitive progress the state has made.

"Our concern is that an industry that already lacks competition and has all sorts of monopoly problems would only get worse if this sale is allowed to go through," Lehman explained.

Koch and other corporate ag conglomerates have said consolidating allows them to provide better products to farmers more efficiently. The hearing is set for Saturday on Main Street in Nevada.

In addition to reducing competition for fertilizer, Lehman argued the sale would increase prices for farmers, and ultimately mean higher food prices for Iowans. He wants Khan to hear stories firsthand, from the people on the ground in Nevada.

"We know that we might not be able to have a dialogue with the people who are investigating this situation, because they need to be impartial," Lehman acknowledged. "But our farmers need to tell their story about how the industry is already in a monopoly state."

Some 18 other ag organizations have joined the Iowa Farmers Union calling on the FTC and the Justice Department to investigate the proposed sale.

A farm group is helping Iowa agriculture producers find ways to reduce the amount of nitrogen they use on their crops.

Excess nitrates can wind up in ground and surface water, and cause health problems.

Practical Farmers of Iowa is encouraging farmers to find just the right amount of nitrogen they need for their crops - while avoiding applying too much, which the group says is common.

PFI's Field Crops Viability Coordinator - Chelsea Ferrie - said thanks to federal grants and private funding, the group will pay farmers up to $35 for every acre that has a lower than normal yield if they didn't apply enough nitrogen.

"No cost to the farmer, either," said Ferrie. "We're trying to help incentivize them. This is something that farmers want to do - I mean, they want to be good stewards of the land - but also, that they need to have a profitable farm."

The application period for the program is open through the end of April.

To help them reach the right nitrogen balance, Ferrie said PFI will help farmers on the front end of the process, too - so they aren't left guessing how much to apply.

"Talk through what your typical fertilizer plan is, and what your reduction plan would be," said Ferrie. "Then you would implement this year, going into the spring and into the season."

Farmers have relied on nitrogen-based fertilizers for generations - but when applied in excess, nitrates run off into ground and surface water, posing health concerns for animals and people.

Pesticides are still common in agriculture. Organic producers who avoid them have seen ups and downs in pushing for stronger regulations, and they point to a South Dakota example of the harm associated with widespread use among neighboring farms.

At the heart of the regulatory fight is the application of the weed-killing pesticide dicamba, and how it can drift from one farm to another. Last month, a federal court blocked "over the top" spraying of dicamba products, but the EPA followed with an order to allow the spraying of existing supplies.

Glenn Pulse, co-owner of an organic farm in Vermillion, said a 2017 drift incident had a big impact on his operation.

"Our entire farm was covered. We lost a lot of livestock, and thousands of bees were killed," he explained.

It also resulted in health concerns for his family, having to regain his organic farmer certification, and a legal battle over restitution. Groups such as the National Family Farm Coalition have been fighting what they call the deregulation of these chemicals, arguing the drift and runoff effect has damaged millions of crops.

Dicamba-manufacturing companies deny responsibility, instead blaming farmers who apply it for not following guidelines.

The EPA has said there were already millions of gallons of dicamba in circulation prior to the court's ruling, prompting the agency's order. Pulse feels there are farmers who are careful in spraying chemicals, but he wants stronger enforcement against those he describes as "loose cannons."

"The guys that are not following the labels and they're spraying in weather conditions that are not favorable, that is where, I would say, 90% of the problems are happening with drift incidents," Pulse said.

His calls for better responses to these incidents coincide with policy demands to heavily restrict dicamba products. Meanwhile, Rep. Dusty Johnson, D-South Dakota, is the main sponsor of a bill supporters say would assure uniformity in national pesticide labeling under federal law. But opponents argue it would limit longstanding state and local pesticide safety rules.
