What to know about Alvin's water
Alvin ranks #938 out of 1067 cities in Texas for water quality, placing it among the lowest-rated in the state.
Alvin 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 0.03 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 90 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
