Whether your home in Kootenai was built before or after 1986 matters more than the citywide median of 2007, because the 1986 federal lead restrictions cover plumbing installed after that point.
Most homes in Kootenai were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Kootenai
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Pre-1986 construction accounts for about 25% of Kootenai homes; older plumbing in any of them can still add lead at the tap.

What You Can Do in Kootenai
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Surface Water Treatment Rule, listed in the water-quality records for Kootenai: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
