Analysis

What to know about Coachella's water

Coachella ranks #587 out of 694 cities in California for water quality, placing it among the lowest-rated in the state.

Coachella relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

Hexavalent chromium (chromium-6) was detected at 20.00 µg/L, above California's 10 µg/L limit. There is no federal MCL, but the EPA is reviewing evidence linking long-term exposure to cancer risk.

The system has seen 14 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
