Key Contaminants Detected in Edinburg
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Edinburg's Housing Stock?
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
Edinburg's housing stock skews relatively recent, with a median build year of 2002. Homes constructed after 1986 avoid the lead-soldered copper joints that were standard before the federal ban — reducing aggregate risk from plumbing as a contamination pathway.
Most homes in Edinburg were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Edinburg: Remediation Cost in Perspective
At current valuations, Edinburg falls in the moderate remediation-share tier — a level where treating this as a budgeted line item rather than an ad-hoc expense is the practical approach.
Remediation costs are moderate relative to home values in Edinburg. The estimated $1,225–$3,000 range is manageable for most homeowners but still worth budgeting for. Home values are 38% below the Texas average.
Protecting Children from Lead in Edinburg
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.
Generally, the structural picture for Edinburg runs in a quiet direction. Aggregate sampling rests under the federal action benchmark, and 17% of housing comes from the pre-rule era — a contained local footprint. That dual signal keeps lead in the background of local concerns, while a one-faucet measurement still answers a different question than any system average can: what is actually flowing from one specific tap on a given morning.

Climate-Related Water Risk for Edinburg
Across the multi-decade NFIP program, Edinburg has logged 701 filed flood claims — a tally that corresponds with 100% of local ZIP codes carrying FEMA flood zone designations. For water quality, the implications extend beyond property damage: when flooding reaches the magnitude this area's record implies, water supply systems face compounding stress. Treatment plants handling contaminated floodwater intake face sharply elevated contaminant loads. Private wells in low-lying FEMA zones are vulnerable to surface infiltration during each major event. Distribution networks can experience pressure-inversion backflow, drawing untreated water back into the supply. These are not remote possibilities at this exposure level.
Edinburg has a significant flood history with 701 FEMA flood insurance claims on record, averaging $12,648 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>$1,925</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.
