Screening: quick check, not lab-grade
Silver Lake Research
Lead, bacteria, nitrate, copper, iron, chlorine, hardness and pH
What it can't tell you: Each test gives a yes/no or a rough range, not a lab number, and it cannot detect PFAS or arsenic.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Roswell, no regulated PFAS were detected in EPA's 2024 testing. ROSWELL MUNICIPAL WATER SYSTEM (PWSID NM3520203) has a Purity Score of 74/100 (confidence: high), assessed at the water-system level and computed only from contaminants that were measured.

Groundwater (primary source of record in EPA SDWIS).
None of the 29 PFAS in EPA's UCMR 5 testing (2023-07-24 to 2024-01-09) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
Lead is not in Roswell's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
PurityMap's current record for Roswell holds 33 findings: 1 above a reference, 2 detected within the reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
