Housing & Infrastructure in Maryville
With 47% 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
Roughly balanced between older and newer construction, Maryville shows a median build year of 1983 - a mid-range figure that places meaningful amounts of the residential inventory on both sides of the 1986 federal plumbing-solder ban.
Most homes in Maryville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Maryville Homeowners
In Maryville, property wealth outpaces what documented remediation typically demands - the equity burden lands well within the low tier.
Remediation costs in Maryville are relatively low compared to home values. The $1,550–$3,450 estimated range is a small fraction of median property value. Home values are 20% above the Tennessee average.
Lead Exposure Risk for Children in Maryville
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 47% of Maryville stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.

Historical NFIP Claim Context in Maryville
Historical NFIP data for Maryville contains 24 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $16,859. Among ZIP codes with claim records, 67% 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>$2,400</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.
