When a fire started on the property next door to Ray Cano’s home, the neighbors used Cano’s hose and well to fight the flames. Running the pump at full throttle, they managed to control the blaze until the fire department arrived. Then, the well’s pump sputtered to a stop.
In a 6-to-3 ruling, the court rejected arguments by a county in Hawaii and the Trump administration that only pollution discharged directly into navigable waters requires permits.
Voluntary agreements in California have been touted as an innovative and flexible way to improve environmental conditions in the Sacramento-San Joaquin Delta and the rivers that feed it. The goal is to provide river flows and habitat for fish while still allowing enough water to be diverted for farms and cities in a way that satisfies state regulators. But no one said this would be easy.
California’s Central Valley — one of the richest agricultural regions in the world — is sinking. During a recent intense drought, from 2012 to 2016, parts of the valley sank as much as 60 centimeters per year. “It isn’t like an earthquake; it doesn’t happen, boom,” says Claudia Faunt, a hydrologist with the U.S. Geological Survey. But it is evidence of a slow-motion disaster, the result of the region’s insatiable thirst for groundwater.
San Joaquin Valley farmers may soon have another crop to sell along with almonds, tomatoes, and peppers — the groundwater beneath their land.
NASA researchers have developed new satellite-based, weekly global maps of soil moisture and groundwater wetness conditions and one to three-month U.S. forecasts of each product. While maps of current dry/wet conditions for the United States have been available since 2012, this is the first time they have been available globally.
March rain has left Salt River Project reservoirs as full as they’ve been in a decade. The company is discharging water to make room for the runoff, providing a boost to the underlying aquifers.
The number of known military sites where cancer-linked firefighting foam may have contaminated groundwater across the United States has jumped to 651 from 401, and the cleanup bill will likely cost billions of dollars more than initially estimated, according to a new Pentagon report.
The new report was directed by Defense Secretary Mark Esper as part of his focus on PFAS contamination and lists hundreds of additional locations, many of them Army National Guard sites, in all 50 states where area groundwater may have been contaminated by the chemical compound.
Water plays a lead role in the state’s political theater, with Democrats and Republicans polarized, farmers often fighting environmentalists and cities pitted against rural communities. Rivers are overallocated through sloppy water accounting. Groundwater has dwindled as farmers overdraw aquifers. Many communities lack safe drinking water. Native Americans want almost-extinct salmon runs revived. There is talk, too, of new water projects, including a massive new tunnel costing billions of dollars.
California began regulating surface water in rivers and streams in 1914, but it took the state another 100 years to look underground.
In 2014, for the first time in its history, California passed a law regulating the use of groundwater – the resource on which 85% of its population and much of its $50bn agriculture industry rely.
