Worthington's drinking water received a grade of F (33.7 out of 100), indicating failing water quality. The city's 2 water systems serve approximately 1,823 residents using groundwater.

Lead levels were measured at 33.5 ppb (90th percentile), which exceeds the EPA action level of 15 ppb. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 164 violations on record, including 2 health-based violations. 13 remain unresolved.

Worthington ranks #499 out of 559 cities in Pennsylvania for water quality, placing it among the lowest-rated in the state. Worthington 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, Worthington may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 41 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

02What's in Worthington's water

Every contaminant flagged in Worthington, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.

Over Limit — EPA Action Level: 15 ppb

Exceeds the EPA action level. Lead enters at the service line, not the treatment plant — your address matters more than the city average. Lead service line replacement and an NSF 53-certified point-of-use filter are recommended.

04Where Worthington's water comes from

Worthington's drinking water is drawn from underground aquifers through wells.

Source

Groundwater

Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.

Treatment

Local treatment

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

2 systems

2 water systems, operated under local government ownership.

Delivery

1,823 people

Residents served across Worthington's service area.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by local government ownership and serves approximately 1,823 people through 2 water systems.

07What to do at home

Steps matched to what testing actually found in Worthington's water — not generic advice.

Because of lead

Filter drinking & cooking water

NSF 53-certified pitcher or under-sink filter. Lead level (33.5 ppb) exceeds the EPA action level of 15 ppb

Because lead was detected

Flush taps & check your service line

Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.
