Housing & Infrastructure in Tigrett
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Although a small portion of Tigrett's homes predate 1986, the median build year of 2005 indicates the majority of the city's residential plumbing was installed after lead solder was banned — which tends to reduce the plumbing-related component of lead exposure at the household level.
Most homes in Tigrett were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Tigrett Homeowners
In Tigrett, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Tigrett are relatively low compared to home values. The $300–$800 estimated range is a small fraction of median property value. Home values are 17% below the Tennessee average.
Lead Exposure Risk for Children in Tigrett
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.
Older homes from the pre-rule era make up 16% of Tigrett's inventory, a contained slice. Citywide aggregate readings stay below 0.015 mg/L under EPA Lead and Copper Rule monitoring, suggesting systemic lead is not a dominant local concern. What the aggregate cannot do is reflect conditions inside any single building, where interior plumbing age, water chemistry, and stagnation patterns interact differently than they do across thousands of service connections combined into one figure.

What You Can Do in Tigrett
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
