Top Contaminants in Coatesville Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Coatesville
With 55% 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
For residents trying to assess tap water risk in Coatesville, the median build year of 1988 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Coatesville 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 Coatesville Homeowners
Low proportionality — that's the Coatesville picture when remediation costs are placed against typical home equity.
Remediation costs in Coatesville are relatively low compared to home values. The $2,000–$4,100 estimated range is a small fraction of median property value. Home values are 42% above the Pennsylvania average.
Lead Exposure Risk for Children in Coatesville
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 55% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Coatesville.

Flood & Climate Risk in Coatesville
FEMA data shows 100% of Coatesville's ZIP codes mapped into designated flood zones, paired with an NFIP record of 87 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Coatesville has a moderate flood history with 87 FEMA claims averaging $18,206 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>$3,000</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.
