What's in Maurepas's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Maurepas Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Post-1986 construction is where the lower lead-solder risk lives, because that's when the federal ban on lead solder in plumbing took effect. In Maurepas, where the median build year is 1992, the housing stock falls broadly on the newer side of that threshold — a distribution that moderates aggregate plumbing-era risk compared to older housing markets.
Most homes in Maurepas were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Maurepas
Given current Maurepas valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Maurepas are relatively low compared to home values. The $950–$2,400 estimated range is a small fraction of median property value. Home values are 47% above the Louisiana average.
Maurepas: Lead Risk & Vulnerable Populations
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.
28% of housing in Maurepas predates the federal action against lead solder — a contained share — and aggregate readings stay beneath the regulatory benchmark. Lead therefore sits in a quiet position on the local water-quality picture, with single-home draws as the standard tool for confirming any one address.

Maurepas: Flood History & Water Damage Risk
The National Flood Insurance Program builds its dataset one claim at a time — each filed claim represents a property where flood damage was severe enough to trigger an insurance payout. For Maurepas, that dataset has accumulated 1467 such events across the program's multi-decade history. 100% of ZIP codes here carry official FEMA flood zone designations, reflecting federal assessments of where flood risk is concentrated. Together, those data points describe a community with a documented, substantial flood exposure — the kind that shapes not just property risk but also the periodic reliability of water supply infrastructure. When flood events reach that scale, treatment systems face peak-load contamination stress, private wells become vulnerable to surface water intrusion, and the distribution network can experience backflow conditions that allow untreated water to re-enter the system.
Maurepas has a significant flood history with 1,467 FEMA flood insurance claims on record, averaging $18,680 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>$1,500</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.
