Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile

Newer construction dominates Frederick's residential inventory, as reflected in a median build year of 2005. The practical implication is that lead-soldered copper plumbing joints — a pre-1986 standard now federally prohibited — are an exception rather than the rule in this city, though they remain present in the older fraction of the housing stock.

Most homes in Frederick were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Frederick: Lead Risk & Vulnerable Populations

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.

In Frederick, the older-stock footprint runs at 19% — a contained slice — and aggregate utility readings land safely under the EPA action mark. That keeps lead off the local priority list, with a one-faucet draw remaining the only direct read on a specific address.

Frederick: Flood History & Water Damage Risk

Est. Claims/Year

Frederick has a moderate flood history with 12 FEMA claims averaging $4,527 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>$2,700</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.

What You Can Do in Frederick
