Key Contaminants Detected in New Market
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is New Market's Housing Stock?
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
Housing age is a rough starting point, not an answer. New Market has a median build year of 1993, but any single home may be older or newer than that figure, may have had plumbing replaced, or may still have original fixtures. Lead can also come from a service line or older brass fittings, so a water test or a check of the utility's service line inventory says more about one address than the citywide build year does.
Most homes in New Market were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

New Market: Remediation Cost in Perspective
Low tier for New Market: remediation estimated at up to 1% of what homes are worth.
Estimated remediation costs in New Market can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 19% above the Maryland average.
Protecting Children from Lead in New Market
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Several limits apply to the lead numbers for New Market. The figure shown is an average of 90th-percentile results from ZIP codes in the city, and it is below 0.010 mg/L; the federal action level of 0.015 mg/L applies to each water system's own 90th percentile, not to an average like this one, and being below it does not make water free of lead. About 21% of local homes were built before 1986. A test at the home's own tap shows its level, and a filter certified to NSF/ANSI 53 for lead reduction is an option if a test finds lead.

Historical Flood-Claim Evidence for New Market
Historical NFIP data for New Market contains 4 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $1,736. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The $500 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.

What You Can Do in New Market
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Toxaphene, listed in the water-quality records for New Market: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
