Top Contaminants in Jonesville Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Jonesville
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 Jonesville — median build year 1971 — 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 Jonesville 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 Jonesville Homeowners
Elevated equity share — Jonesville sits in the high tier when estimated remediation is measured against property values.
At 5.7% of home value, remediation costs in Jonesville represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $3,280–$6,760. Home values here are 50% below the Louisiana average.
Lead Exposure Risk for Children in Jonesville
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 Jonesville 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 Jonesville
The NFIP record for Jonesville is not ambiguous: 1190 claims filed and 100% of ZIP codes in FEMA-designated flood territory add up to a substantial flood exposure profile. For a water quality assessment, that profile matters because flooding doesn't just damage property — it can temporarily compromise the systems that deliver safe drinking water, from overwhelmed treatment plants to infiltrated private wells to backflow events in distribution infrastructure.
Jonesville has a significant flood history with 1,190 FEMA flood insurance claims on record, averaging $9,333 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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>$4,920</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.
