Housing Age Profile
Median construction year in Irwin: 1962, set against the 1986 federal lead limits for new plumbing.
Over half of homes in Irwin were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Irwin

Irwin: Lead Risk & Vulnerable Populations
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.

Irwin: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Irwin contains 63 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $10,016. 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 $300 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 Irwin
- 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 Surface Water Treatment Rule, listed in the water-quality records for Irwin: 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 72% of homes built before 1986, lead solder is a real possibility.
