The team has created a Drinking Water Tool that allows Californians to find out where their drinking water comes from and see where groundwater sources are likely contaminated with unsafe levels of arsenic, nitrate, hexavalent chromium and 1,2,3-Trichrolopropane. Screenshots of the tool show levels of arsenic contamination in community water systems (left) and community water systems and domestic wells combined (right).
