What's in La Marque's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
La Marque Infrastructure Age
With 57% 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 La Marque - 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 La Marque were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in La Marque
The La Marque equity share sits above the low tier but short of the range where remediation becomes a heavy financial burden - the cost-to-value ratio is moderate, and deliberate planning is the key practical lever for most homeowners.
Remediation costs are moderate relative to home values in La Marque. The estimated $1,500–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 8% below the Texas average.
La Marque: 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.
Practically, the structural drivers in La Marque - 57% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark - make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.

La Marque: NFIP Claim Records and Water-Quality Context
Historical NFIP data for La Marque contains 1,691 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $25,864. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,300</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
