PFAS Tests for Kalamazoo Municipal Drinking Water Show Results Within Safe Drinking Water Guidelines

Recent PFAS testing of water pumping stations serving the Kalamazoo municipal drinking water system have found results well within the safe drinking water guidelines of 70 parts per trillion (ppt) set by the Environmental Protection Agency.

Fifteen water pumping stations in the City of Kalamazoo Public Water Supply System were sampled on June 15, 2018. None of the tests revealed levels of PFOA/PFOS above the 70 ppt health advisory level. Of the 15 samples, 12 results were “non-detections,” and 3 stations had detectable levels below 70 ppt.

1 part per trillion is equal to roughly one drop of impurity per 16 million gallons of water, or per 24 Olympic-sized swimming pools.

All “baseload stations,” those which typically operate daily to provide water to customers, revealed no detection of PFOA/PFOS. The three stations at which low levels were detected are considered “peaking stations”.

The three “peaking stations” where low levels were detected will only be activated in case of emergency for fire response, system flushing, or in times of peak demand if other water stations cannot meet the demand.

Kalamazoo municipal drinking water continues to be safe for human consumption, for pets, gardens, cooking, washing and all other regular uses.

These tests were conducted as part of a state-wide study of PFOA/PFOS levels in public water supplies by the Michigan PFAS Action Response Team (MPART). While these results do not indicate a public health concern, the City of Kalamazoo will follow directions from the State of Michigan regarding future monitoring of these chemicals. A second round of testing will occur within a month and wells will be tested quarterly.

About the U.S. Environmental Protection Agency Lifetime Health Advisory Level

The U.S. Environmental Protection Agency has established a lifetime health advisory level for PFAS in drinking water. The level represents an amount of average daily exposure below which no harm is expected from these chemicals over the course of a person’s lifetime. This level is considered protective of everyone, including pregnant women, young children, and the elderly, and includes a 300% margin of safety.
