How Old Is Onaga's Housing Stock?
With 71% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Onaga's housing stock is predominantly older, with a median build year of 1969 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here - a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.
Over half of homes in Onaga were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Onaga: Remediation Cost in Perspective
When remediation costs are measured against Onaga home values, the resulting ratio is in the low tier - addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.
Remediation costs in Onaga are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 20% above the Kansas average.
Protecting Children from Lead in Onaga
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 71% of the Onaga inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.
