摘要

New water quality results for groundwater on the Central Coast presented troubling news about nitrate levels at the Sustainable Ag Expo, held in San Luis Obispo, Calif., in late November.Steve Deverel, hydrologist working for the Central Coast Groundwater Coalition (CCGC), reported that tests of hundreds of Central Coast domestic wells in 2013-14 revealed high nitrate concentrations throughout the Salinas Valley, and in farming regions in Pajaro, Gilroy, Hollister and Santa Maria groundwater basins.The findings characterize nitrate present in domestic wells that are a source of drinking water, a supply generally within 400 feet of the surface.Deverel noted, "Nitrate levels in groundwater exceed the maximum contaminant level, the EPA's safe drinking water standard, in 58% of domestic wells in the Salinas Valley. In general, nitrate concentrations decreased with increasing depth."He said preliminary results from studies he is completing this winter seem to indicate that much of the accumulation of nitrate has occurred in recent decades, primarily since the 1980s.Deverel and his team at Hydrofocus Inc., based in Davis, are using radioisotope testing to determine the age and source of nitrate contamination. They are analyzing findings from 830 wells in all, 588 of which the coalition sampled directly. They also obtained recent data from local and state government agencies.
