Frederick Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
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.

How Remediation Costs Compare in Frederick
Because property values in Frederick comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Frederick are relatively low compared to home values. The $1,750–$3,900 estimated range is a small fraction of median property value. Home values are 1% below the Colorado average.
Frederick: 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.
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
Within the NFIP's national dataset, Frederick falls in moderate-exposure territory — 12 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
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
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. Filters rated for Total Trihalomethanes (TTHM) can reduce the most common contaminant found in Frederick's water.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
