Likely Pipe Material

With 69% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.

Source: U.S. Census Bureau American Community Survey (ACS).

Housing Age Profile

Plumbing risk in older housing is tied to the period before 1986, when lead pipes and lead solder were still permitted in new plumbing. Loyal's median build year is 1977, and properties from before that year might still contain lead-bearing joints or pipes. Much of that risk sits inside individual properties, which city-level water quality averages don't capture.

Over half of homes in Loyal were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Loyal

Homes Built Before 1986
0.0116
mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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.

Several steps can clarify lead exposure for a Loyal household. The area figure, an average of ZIP-level 90th-percentile results, is 0.010 mg/L or higher, and the pre-1986 share of local homes is about 69%. The water utility's lead service line inventory shows how a home's service line is classified, a certified laboratory test measures lead at the tap, and a filter certified to NSF/ANSI 53 for lead reduction is an option where results show lead.
