Housing Age Profile
What does a median build year of 1987 mean for water safety in Clarington? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Clarington were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Clarington: Remediation Cost in Perspective
Is remediation financially manageable for Clarington homeowners? At a moderate equity share, generally yes — with deliberate budgeting ahead of time.

Protecting Children from Lead in Clarington
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.
If 56% of the Clarington inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Climate-Related Water Risk for Clarington
FEMA data shows 100% of Clarington's ZIP codes mapped into designated flood zones, paired with an NFIP record of 28 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Clarington has a moderate flood history with 28 FEMA claims averaging $10,368 per payout. 100% 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>$1,600</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.
