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
Reading the housing data for Johnson City, with a median build year of 1987, reveals a community where neither old nor new construction dominates. That balanced profile means lead-solder-era plumbing is present throughout a meaningful portion of the residential inventory - with risk concentrated in properties built before 1986 and most acute in those that predate 1970.
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
Across the Johnson City housing market, the estimated remediation share lands in a middle tier - not a minor footnote, but not a prohibitive burden either; the cost-to-value ratio reflects a moderate equity commitment, one that sits above routine maintenance territory and warrants a dedicated line in the household budget.
Remediation costs are moderate relative to home values in Johnson City. The estimated $1,733–$3,567 range is manageable for most homeowners but still worth budgeting for. Home values are 4% above the Tennessee 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.
Wherever 39% of local housing was built before solder rules changed - as is the case in Johnson City - a faucet-level sample closes the gap that aggregate utility data cannot.

Historical Flood-Claim Evidence for Johnson City
Historical NFIP data for Johnson City contains 115 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $41,323. Among ZIP codes with claim records, 50% 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>$2,533</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.
