Analysis

What to know about Altoona's water

Altoona ranks #417 out of 560 cities in Pennsylvania for water quality, placing it below average in the state.

The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.

Hexavalent chromium (chromium-6) was detected at 0.33 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 25 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
