“Because this study is limited to three common contaminants, the results likely underestimate the actual number of Californians impacted by unsafe drinking water from other chemicals. The at-risk populations are found across the state, but are concentrated, not surprisingly, in poor, mostly rural areas in the San Joaquin Valley that rely heavily on privately-owned wells for domestic water.” ~Dr. Lara Cushing, the UCLA Fielding School of Public Health’s Jonathan and Karin Fielding Presidential Chair in Health Equity and an assistant professor of environmental health sciences
