Research Project Will Help Scientists Understand Major California Storms

 “Atmospheric rivers” play a huge role in determining California’s water supply. As Amy Quinton reports from Sacramento, a team of scientists is launching state-of-the-art equipment by land and sea to study the storms.

California’s drought isn't just causing wells to go dry, it's also contributing to a long running water pollution problem.

A new study by the U.S. Geological Survey looked at over 100 private domestic drinking water wells in the San Joaquin Valley. It found that around 1 in 4 had uranium levels above those considered safe by the EPA. Most of the wells were on the east side of the valley, which is home to sediment from the Sierra Nevada which naturally contains uranium.

Wildlife Agencies See Near Collapse Of 2014 Salmon Species

California and federal wildlife agencies say the entire winter-run of naturally-spawning Chinook salmon may have collapsed in 2014. As Amy Quinton reports from Sacramento, the agencies will begin releasing triple the number of hatchery-raised juveniles next week.

High water temperatures in the Sacramento River last summer and fall caused 95-percent of winter-run salmon egg and fry to die.

Maria Rea: “I think this is really unprecedented really that we’ve seen this level of temperature mortality.”

Study: California Pesticde Assements Thorough, Slow

The National Academy of Sciences released a report today on how the California Department of Pesticide Regulation assesses the safety of pesticides. It found that DPR assessments are thorough, but not very timely. It typically takes six to ten years. 

The report also says DPR needs to create a clearer process for ranking the hazard of pesticides and identifying which pesticides should take priority. Paul Tower with the Pesticide Action Network says the report confirms concerns the group has raised over the years.

California Farmers Turn Sugar Beets Into Energy

Struggling sugar beet farmers in the San Joaquin Valley are turning their crop into energy instead of sweetner. A pilot plant could prove to be good for the environment and the economy. 

They're called "energy beets." They look like a red table beet but, but they're larger, white, and very high in sucrose. Sugar beets in California date back to the late 1800's.

Kaffka: "Beets have been grown here commercially longer than any other place."

New Grant Aims To Help Save Valley's Tricolored Blackbird

A federal grant announced today could give California dairy farmers incentive to help save the Tricolored Blackbird. As Amy Quinton reports from Sacramento, the population of the bird has plummeted in the last four years.

California’s Tricolored Blackbirds are found mainly in the southern San Joaquin Valley and often nest in fields where dairy farmers grow feed. Come harvest time, nestlings are often plowed under. That, combined with wetland loss and drought, has led to a population decline of 44 percent since 2011.

California's air regulators are increasingly turning their attention to a greenhouse gas that has largely gone overlooked - methane. 

According to the U.S. EPA, when it comes to climate change, methane emissions have an impact 20 times greater than CO2 emissions, pound for pound.

That's why Governor Jerry Brown singled out the gas during his inaugural address this month as part of his plan to combat climate change. 

California Air Resources Board

The LA Times recently called Mary Nichols a “rock star.” In 2013 Time Magazine called her one of the 100 most influential people in the world and the Thomas Edison on environmentalism. She’s the chair of the California Air Resources Board, and if it has something to do with air quality or climate change in the state, she probably has something to say about it.

Department of Pesticide Regulation - Facebook

California has announced stringent new rules on a common pesticide used in the production of strawberries, almonds, tomatoes, and peppers.

Chloropicrin is a fumigant that is used to treat the soil before crops are planted. The new rules are more stringent than those adopted by the U.S. EPA in 2012.

Under the new regulations from the state’s Department of Pesticide Regulation, farmers will be required to provide larger buffer zones when applying the chemical, and will be required to reduce the size of fields where it is applied.

Independent Scientific Study On Fracking In California Released

Jan 14, 2015

The oil extraction process known as hydraulic fracturing is much different in California than in other states. As Amy Quinton reports from Sacramento, that’s the finding of the first independent scientific assessment required under the state’s new fracking regulations.

California has shallow, vertical fracking wells that require about 140,000 gallons of water per well to extract oil. That’s millions of gallons less than other states. But the fluids contain more concentrated chemicals.
