Top Contaminants in Mohnton Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Mohnton
With 62% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Reading the housing age data for Mohnton — median build year 1970 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Mohnton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Mohnton Homeowners
The equity share of documented remediation in Mohnton is high — a cost-to-value ratio that places this market in the elevated tier and means most homeowners are weighing a financial decision where scoping by urgency, mapping costs against household budget, and knowing what assistance options exist are practical steps that can materially improve outcomes.
At 2.3% of home value, remediation costs in Mohnton represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $4,380–$9,060. Home values here are 36% above the Pennsylvania average.
Lead Exposure Risk for Children in Mohnton
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
62% — that captures the slice of Mohnton housing built before the federal ban on solder containing lead. Aggregate utility samples have also moved past the action threshold, meaning the system-level data and the housing-inventory data point the same direction. Households with kids or pregnant residents face a practical question that only a faucet sample can answer for one specific address, with certified filter options through retailer networks available where confirmed results warrant it.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

Flood & Climate Risk in Mohnton
FEMA data shows 100% of Mohnton's ZIP codes mapped into designated flood zones, paired with an NFIP record of 27 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Mohnton has a moderate flood history with 27 FEMA claims averaging $8,368 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$6,620</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
