What's in Columbiaville's Water?

Columbiaville Infrastructure Age
With 73% 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.

Housing Age Profile
The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing — from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Columbiaville, where the median build year is 1975, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.
Over half of homes in Columbiaville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Columbiaville
Low proportionality — that's the Columbiaville picture when remediation costs are placed against typical home equity.
Remediation costs in Columbiaville are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 2% above the Michigan average.
Columbiaville: 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.
Wherever 73% of local housing was built before solder rules changed — as is the case in Columbiaville — a faucet-level sample closes the gap that aggregate utility data cannot.
