NSF/ANSI 53 lead-certified pitcher, under-sink or RO. MEDFORD WATER DEPT. (MWRA)'s latest Lead and Copper Rule result was 8.3 ppb at the 90th percentile (2026–2026), under the 15 ppb action level but well above zero, and there is no safe level of lead.
Based on EPA records for MEDFORD WATER DEPT. (MWRA), yes: nsf/ansi 53 lead-certified pitcher, under-sink or ro is the first fix (see the evidence table above).
An NSF/ANSI 53 lead-certified filter: a pitcher for renters, an under-sink unit for owners, or RO if you also want PFAS and dissolved-solids coverage.
MEDFORD WATER DEPT. (MWRA)'s latest Lead and Copper Rule 90th-percentile result was 8.35 ppb (2026-01-01 to 2026-06-30), below the 15 ppb action level. Lead enters from service lines and home plumbing, so test at the tap if your home is older.
No. None of the 116 UCMR5 PFAS results for MEDFORD WATER DEPT. (MWRA) (2025-01-13 to 2025-10-06) were at or above the reporting limit.
Look for: NSF/ANSI 53 lead reduction (or NSF/ANSI 58 RO)
MEDFORD WATER DEPT. (MWRA)'s latest Lead and Copper Rule result was 8.3 ppb at the 90th percentile (2026–2026), under the 15 ppb action level but well above zero, and there is no safe level of lead. The utility's Q2 2026 service-line inventory also lists 5,128 lead service lines and 4,657 lines of unknown material. Lead comes from pipes, not the source water, so a point-of-use filter certified for lead is the right tool; RO is the most thorough.
| Evidence | Result | EPA limit | Period | Source |

| Lead (90th percentile of tap samples) | 8.35 ppb (lead 90th percentile) | 15 ppb | 2026-01-01 → 2026-06-30 | EPA SDWIS/ECHO 2026Q2 |
