Partial data: State Water Board lab results show 3 of the 5 active sources City of Winters sampled above California's hexavalent chromium limit of 10 µg/L (state MCL, in effect since October 1, 2024). The highest average is 22.2 µg/L at GRANT AVENUE WELL RAW - PENDING (5 samples since October 1, 2024, latest June 5, 2026). City of Winters's treated or delivered water was not sampled, and its other sources average within it, so these results do not show the water it serves above the limit, and they are not counted toward its verdict. Source: State Water Resources Control Board lab results (updated 2026-09-15).
