LANSING BOARD OF WATER & LIGHT (EPA PWSID MI0003760) delivers groundwater to 166,000 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. The utility's 2025 CCR reports moderately hard water.
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
The records describe the system. A certified lab test shows what reaches your glass.
Lithium 19.6 µg/L, above the 10.0 µg/L EPA health reference level
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

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 Lansing, no regulated PFAS were detected in EPA's 2024 testing. LANSING BOARD OF WATER & LIGHT (PWSID MI0003760) has a Purity Score of 100/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
LANSING BOARD OF WATER & LIGHT (PWS ID MI0003760) is the public water system on record for Lansing, Michigan, serving about 166,000 people. Confirm the utility on your water bill before acting on a specific finding.
Groundwater (primary source of record in EPA SDWIS).
None of the 29 PFAS in EPA's UCMR 5 testing (2024-02-05 to 2024-08-08) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
Lead is not in Lansing'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 Lansing holds 32 findings: 1 above a reference, 1 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.
Lansing's water is recorded as 5.7 gpg, moderately hard. Hardness is an aesthetic and plumbing characteristic, not a health-based limit.
