Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Clarkston's Housing Stock?
With 49% 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
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Clarkston, the median build year of 1993 indicates that plumbing age is a material factor in local lead risk — with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Clarkston were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Clarkston: Remediation Cost in Perspective
In Clarkston, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Clarkston are relatively low compared to home values. The $400–$1,667 estimated range is a small fraction of median property value. Home values are 106% above the Michigan average.
Protecting Children from Lead in Clarkston
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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet — and where 49% of Clarkston homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.

Climate-Related Water Risk for Clarkston
33% of ZIP codes in Clarkston are mapped into FEMA-designated flood zones, and the NFIP records 7 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Clarkston has a moderate flood history with 7 FEMA claims averaging $954 per payout. 33% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$1,000</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
