Key Contaminants Detected in New Philadelphia
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is New Philadelphia's Housing Stock?
With 74% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing — from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In New Philadelphia, where the median build year is 1964, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.
Over half of homes in New Philadelphia were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

New Philadelphia: Remediation Cost in Perspective
Although the New Philadelphia remediation share is moderate, it remains reachable for most homeowners who plan for the expense in advance.
Remediation costs are moderate relative to home values in New Philadelphia. The estimated $1,750–$3,900 range is manageable for most homeowners but still worth budgeting for. Home values are 4% below the Ohio average.
Protecting Children from Lead in New Philadelphia
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.
Wherever 74% of local housing was built before solder rules changed — as is the case in New Philadelphia — a faucet-level sample closes the gap that aggregate utility data cannot.

Climate-Related Water Risk for New Philadelphia
New Philadelphia's flood exposure sits in the moderate range: 79 NFIP claims on record and 100% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
New Philadelphia has a moderate flood history with 79 FEMA claims averaging $6,465 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>$2,700</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.
