Key Contaminants Detected in Johnson City
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Johnson City's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Some cities skew heavily toward one construction era; Johnson City does not. The median build year of 1995 reflects a housing stock where older and newer homes share the market in meaningful proportions. That mixed profile means the city carries moderate aggregate plumbing-era risk - with older homes, particularly those built before 1986, representing the portion of the stock where lead-soldered joints may still be present.
Most homes in Johnson City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Johnson City: Remediation Cost in Perspective
Low proportionality - that's the Johnson City picture when remediation costs are placed against typical home equity.
Remediation costs in Johnson City are relatively low compared to home values. The $1,800–$4,000 estimated range is a small fraction of median property value. Home values are 101% above the Texas average.
Protecting Children from Lead in Johnson City
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 38% of the Johnson City inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.

Historical Flood-Claim Evidence for Johnson City
Historical NFIP data for Johnson City contains 4 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $112,749. 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>$2,500</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.
