Grassy Butte Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Housing age matters for water quality because lead solder was widely used in plumbing until the 1986 federal ban. Grassy Butte's median build year of 1991 suggests a majority of homes were constructed under the newer standard - a meaningful factor when assessing household-level lead risk from tap water.
Most homes in Grassy Butte were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Grassy Butte
The household financial picture for Grassy Butte homeowners is proportionally favorable - addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.

Grassy Butte: Lead Risk & Vulnerable Populations
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.
13% of housing in Grassy Butte predates the federal action against lead solder - a contained share - and aggregate readings stay beneath the regulatory benchmark. Lead therefore sits in a quiet position on the local water-quality picture, with single-home draws as the standard tool for confirming any one address.
