Key Contaminants Detected in Shrewsbury
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Shrewsbury's Housing Stock?
With 48% 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 trying to understand water quality at the household level, the year a home was built often matters more than any city-wide water report. That's because the 1986 federal ban on lead solder in plumbing, and the earlier phase-out of lead pipes before 1970, created sharp discontinuities in residential plumbing risk by construction era. Shrewsbury's median build year of 1982 puts the city in the transition zone: a substantial share of the housing stock postdates the solder ban, but a comparable fraction predates it — with the oldest homes carrying both the solder risk and the pipe risk simultaneously. Whether any individual household sits on the safer or riskier side of these thresholds is the key question, and it's one the city-wide median alone can't answer.
Most homes in Shrewsbury were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Shrewsbury: Remediation Cost in Perspective
The equity-to-remediation ratio in Shrewsbury is moderate — worth planning for but within reach for most property owners.
Remediation costs are moderate relative to home values in Shrewsbury. The estimated $2,400–$4,800 range is manageable for most homeowners but still worth budgeting for. Home values are 37% above the Pennsylvania average.
Protecting Children from Lead in Shrewsbury
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 48% of Shrewsbury 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 Shrewsbury
100% of ZIP codes in Shrewsbury are mapped into FEMA-designated flood zones, and the NFIP records 1 claim reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Shrewsbury has a moderate flood history with 1 FEMA claims. 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>$3,600</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.
