Analysis

What to know about Fort Stockton's water

Fort Stockton ranks #801 out of 1067 cities in Texas for water quality, placing it below average in the state.

Fort Stockton 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.

PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter.

Hexavalent chromium (chromium-6) was detected at 0.06 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

The system has seen 23 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
