Sixty percent of California’s public water supply wells that were tested for so-called forever chemicals contain those compounds, according to research that the State Water Resources Control Board released Wednesday. That same investigation into contamination from per- and polyfluoroalkyl substances also found that groundwater and surface water sampled at airports far exceeded the concentrations detected […]
Determining how climate change is affecting water supplies is difficult in a state like California that swings between floods and droughts, but a new study has found that climate models agree on key metrics that could help water managers in the Golden State.
California water regulators on Tuesday cut the level at which water suppliers must report detecting perchlorate, a chemical used in rocket fuel, fireworks, airbags, and other products. The federal Environmental Protection Agency earlier this year declined to regulate perchlorate, which has been linked to thyroid conditions.
Droughts usually evoke visions of cracked earth, withered crops, dried-up rivers and dust storms. But droughts can also form over oceans, and when they then move ashore they are often more intense and longer-lasting than purely land-born dry spells.
Researchers at the University of California San Diego report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California’s San Joaquin Valley.
