EL CENTRO, Calif. – A growing number of Imperial Valley residents said the area is in serious danger, threatened by a possible change in how water rights are implemented locally, giving just a few people the power to do with water as they please. Alex Cardenas, IID Director Division 1, said, “If they were able to sell water or transfer water out of here it would be absolutely devastating to our economy.”
The San Diego County Water Authority is hosting a social media photo contest during Water Awareness Month in May to celebrate how safe and reliable water supplies fuel the region’s local farms and food production. The “San Diego Grown Photo Contest” on Instagram and Twitter highlights the significance of agriculture to the regional economy. As one of the nation’s top producers of avocados, ornamental trees and shrubs, flowers, succulents, lemons, and other agricultural products, San Diego County’s farms generate nearly $4.8 billion in total annual economic activity on some 250,000 acres.
California Attorney General Xavier Becerra yesterday joined a multistate comment letter objecting to the U.S. Army Corps of Engineers’ (Army Corps) directive to weaken states’ oversight of projects impacting water quality. The Army Corps’ directive would drastically shorten timeframes for state water quality certifications under Section 401 of the Clean Water Act (CWA). This abbreviated timeframe would prevent states from adequately assessing the water quality impacts of proposed federal projects to ensure states’ water resources are protected.
In 2016 the Colorado health department announced the presence of cancer-causing chemicals in drinking water in Fountain, Colo., just outside Colorado Springs. Tests by the Environmental Protection Agency (EPA) discovered that nearby military bases had been leaching toxic chemicals, including substances known as PFASs, into drinking water for decades, potentially contributing to higher-than-normal rates of cancer. The Department of Defense has since admitted their responsibility for at least 55 drinking-water site contaminations worldwide, and the EPA has announced new plans to set drinking-water limits for PFASs by the end of the year.
The unusual event prompted U.S. Geological Survey researcher Emily Montgomery-Brown and her colleagues to look back through 33 years of seismic and water records for the region. They found that rates of shallow seismicity were about 37 times higher during very wet periods versus dry periods. Although scientists have linked earthquakes to heavy rainfall or heavy runoff before this, the evidence connecting the two has been relatively weak or ambiguous, says Montgomery-Brown. In the Long Valley Caldera case, she says, “we’re seeing phenomenal correlation between the seismicity and the stream discharge, and we are seeing about 37 times the number of earthquakes during the wet season as during the dry season.”
A new report paints a grim future for birds that rely on the Salton Sea habitat. Audubon California-released report uses bird-monitoring data from several different sources to show just how the destruction of the Salton Sea ecological habitat has decimated the populations of both pelicans and cormorants endemic to the area. As the Salton Sea recedes, the body of water’s salinity increases, which kills off its tilapia population. Without tilapia, the birds starve.
Following a pretty dry 2017-18 season, the storms came back with a frenzy this season across the Southwest, helping to propel many places to above-average precipitation. It was a fast transition in California in November from the destructive Camp and Woolsey fires in the first half of the month to storms, flooding and mudslides by the end of the month. December had extended dry periods, and most places ended up with below-average precipitation for the month. As a stormier pattern led to frequent storms and atmospheric river events as 2019 started, the heavy precipitation events caused flooding, mudslides and heavy snow.
After pressure from the Defense Department, the Environmental Protection Agency significantly weakened a proposed standard for cleaning up groundwater pollution caused by toxic chemicals that contaminate drinking water consumed by millions of Americans and that have been commonly used at military bases. Standards released by the agency on Thursday eliminated entirely a section that would have addressed how it would respond to what it has described as “immediate threats posed by hazardous waste sites.” Those short-term responses, known as removal actions, can include excavating contaminated soil or building a security fence around a toxic area.
Citing long-running efforts to secure a new Monterey Peninsula water supply and the state-imposed deadline for reducing unauthorized water usage, the county Planning Commission approved California American Water’s desalination plant north of Marina on Wednesday. By a 6-4 vote, the commission backed a use permit for the proposed 6.4 million gallon per day desal plant. The plant is designed to provide about 40 percent of the Peninsula’s planned new water supply to offset the state’s Carmel River pumping cutback order set to take full effect at the end of 2021, as well as reduce pumping from the Seaside basin. The commission’s approval can be appealed to the Board of Supervisors.
Olivenhain Municipal Water District’s 4S Ranch Water Reclamation Facility has won a statewide award. It was named the California Water Environment Association’s 2019 “Small Plant of the Year” at the association’s annual conference on April 12. “OMWD is gratified to have CWEA confirm what we’ve known for years, our 4S Ranch Water Reclamation Facility is second to none,” said Christy Guerin, the district’s director. “The facility produces over a million gallons of recycled water each day through advance treatment processes. Almost every drop of wastewater is reclaimed and converted into a drought-resilient, sustainable water supply.”
