Likely Pipe Material

Housing Age Profile

For residents trying to assess tap water risk in Bonnie, the median build year of 1974 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.

Over half of homes in Bonnie were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Bonnie: Remediation Cost in Perspective

Setting Bonnie remediation figures against its property market, the resulting ratio sits comfortably in the low tier — a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.

Protecting Children from Lead in Bonnie

66%
Homes Built Before 1986
0.0023
mg/L Avg Lead (Limit: 0.015)

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 66% of the Bonnie inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.
