Likely Pipe Material

With 67% 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

For residents trying to assess tap water risk in Denison, the median build year of 1975 is the starting context. It signals that a majority of homes were constructed before 1986 - the year federal rules prohibited lead solder in new plumbing - and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.

Pre-1970 (27%) 1970–1986 (40%) Post-1986 (33%)

Over half of homes in Denison were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Denison: Remediation Cost in Perspective

When estimated remediation is placed alongside median property values in Denison, the resulting ratio is low - a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.

Median Home Value
$188,600
Est. Remediation
$1,500
Remediation as % of home value 0.8%

Remediation costs in Denison are relatively low compared to home values. The $1,000–$2,150 estimated range is a small fraction of median property value. Home values are 17% below the Texas average.

Protecting Children from Lead in Denison

67%
Homes Built Before 1986
0.0028
mg/L Avg Lead (Limit: 0.015)

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.

If 67% of the Denison inventory comes from before the federal ban on lead-bearing solder - and if utility samples sit at or near 0.015 mg/L - the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Denison contains 51 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $58,000.

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>$1,500</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.
