Analysis

What to know about Johnsonburg's water

Johnsonburg ranks #534 out of 560 cities in Pennsylvania for water quality, placing it among the lowest-rated 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.

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, Johnsonburg may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

The system has seen 168 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
