How Old Is Banks's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
A median build year of 1995 in Banks points to a housing stock where post-1986 construction is the norm. That matters because lead solder in plumbing — banned federally in 1986 — is a primary pathway by which older homes can elevate tap water lead above what enters the distribution system.
Most homes in Banks were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Banks
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.
Pre-rule stock in Banks accounts for 5% of the inventory — a modest fraction — and citywide samples land safely beneath the federal action mark.

What You Can Do in Banks
- 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.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
