What's in Knox City's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Knox City Infrastructure Age
With 86% 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
When a city's housing median build year is 1962, as in Knox City, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Knox City 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 Knox City
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Knox City is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Knox City are relatively low compared to home values. The $150–$600 estimated range is a small fraction of median property value. Home values are 71% below the Texas average.
Knox City: 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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 86% pre-rule share in Knox City keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
