Analysis

What to know about Matamoras's water

Matamoras ranks #372 out of 560 cities in Pennsylvania for water quality, placing it below average in the state.

Matamoras 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 0.07 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.

As a small community water system, Matamoras may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

The system has seen 100 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
