Analysis

What to know about Chicora's water

Chicora ranks #297 out of 560 cities in Pennsylvania for water quality, placing it below average in the state.

Chicora 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.

Lead levels exceed the EPA action level of 15 ppb, which typically indicates aging lead service lines or lead solder in the distribution system. An NSF 53-certified filter is strongly recommended for drinking and cooking water.

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

The system has seen 11 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
