Housing & Infrastructure in Cascade
With 82% 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
When a city's housing median build year is 1900, as in Cascade, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Cascade were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Cascade Homeowners
Across the Cascade housing market, the estimated remediation share sits at an elevated level — the cost-to-value ratio here is high enough that addressing documented water and safety issues becomes a material equity decision rather than routine maintenance, and most homeowners benefit from treating it as a structured financial planning exercise.
At 2.4% of home value, remediation costs in Cascade represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $3,430–$7,960. Home values here are 46% below the Maryland average.
Lead Exposure Risk for Children in Cascade
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.
Where 82% of housing predates the federal ban on lead-bearing solder and citywide utility samples sit beyond the regulatory benchmark — as both conditions hold for Cascade — the practical question for families with kids is what arrives at the specific faucet they actually use, not what the citywide average reads. An in-home kit produces that household-specific answer, with certified filter hardware via retailer networks addressing confirmed exposure where it appears.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.

What You Can Do in Cascade
- Test your water at home. City-level data shows averages — your tap may differ. Lead testing is especially recommended given the area's lead levels.
- Install a certified water filter. Filters rated for Stage 2 DBP Rule can reduce the most common contaminant found in Cascade's water.
- Check your home's plumbing. With 82% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
