What's in Montgomery's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Montgomery 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
Lead solder was federally prohibited in new plumbing in 1986. In Montgomery, the median build year of 2005 puts a majority of homes in the lower-risk category for that specific contamination pathway — though the pre-1986 share shown above still carries real exposure potential at the individual household level.
Most homes in Montgomery were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Montgomery
In Montgomery, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Montgomery are relatively low compared to home values. The $1,550–$3,500 estimated range is a small fraction of median property value. Home values are 74% above the Texas average.
Montgomery: 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.
Older homes from the pre-rule era make up 19% of Montgomery's inventory, a contained slice. Citywide aggregate readings stay below 0.015 mg/L under EPA Lead and Copper Rule monitoring, suggesting systemic lead is not a dominant local concern. What the aggregate cannot do is reflect conditions inside any single building, where interior plumbing age, water chemistry, and stagnation patterns interact differently than they do across thousands of service connections combined into one figure.

Montgomery: Flood History & Water Damage Risk
Unlike communities where NFIP data shows minimal flood history, Montgomery's record documents 647 claims and 100% of ZIP codes inside FEMA flood zones — a combination that moves flood-related water quality risk from the background into the foreground of any complete local water assessment. Flooding can overwhelm treatment capacity, contaminate wells, and trigger distribution backflow; at this level of exposure, those mechanisms have likely been activated during significant flood events.
Montgomery has a significant flood history with 647 FEMA flood insurance claims on record, averaging $41,738 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>$2,400</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.
