Housing Age Profile
Plumbing materials follow installation dates, not medians. Weslaco records a median build year of 1986, and a meaningful share of its homes date from before the 1986 federal lead restrictions.
Most homes in Weslaco were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Weslaco
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Weslaco
Historical NFIP data for Weslaco contains 1,011 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $48,681. 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 $2,110 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.

What You Can Do in Weslaco
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Lead and Copper Rule, listed in the water-quality records for Weslaco: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. With 35% of homes built before 1986, lead solder is a real possibility.
