Housing & Infrastructure in Allendale
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
A median build year of 2007 in Allendale 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 Allendale were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Allendale
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.
Even with citywide samples reading clean and just 25% of Allendale homes dating to the pre-rule era, individual-faucet conditions remain a separate question that aggregate utility data cannot resolve for one specific address. That gap is structural, not a function of severity.
