What's in Manvel's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Manvel 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
Copper plumbing joined with lead solder was standard practice through the mid-1980s — a design choice that federal regulators prohibited in 1986. Manvel's residential inventory, centered around a median build year of 2002, is weighted toward the post-prohibition era. That context is relevant because the primary plumbing risk in older homes comes not from the municipal water supply but from what happens as water moves through lead-jointed pipes inside the structure — an exposure pathway that newer homes mostly avoid.
Most homes in Manvel were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Manvel
Equity impact data for Manvel lands in the favorable tier — remediation claims a small slice of what properties here are worth.
Remediation costs in Manvel are relatively low compared to home values. The $1,350–$3,100 estimated range is a small fraction of median property value. Home values are 57% above the Texas average.
Manvel: 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.
Confirming what flows from a specific faucet still requires a one-home draw, even where Manvel averages stay clean and the pre-rule housing share holds at 15%.

Manvel: Flood History & Water Damage Risk
Flood claims in Manvel number 666 under the NFIP, and 100% of ZIP codes fall within FEMA-designated zones — together reflecting a community where flooding is a recurring, significant feature of the local risk environment with direct implications for periodic water supply safety.
Manvel has a significant flood history with 666 FEMA flood insurance claims on record, averaging $29,444 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>$2,100</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.
