August 17, 2018, HOLL., Michigan – Holland Board of Public Works (HBPW) has released its PFAS testing results for both drinking water and the effluent water discharged from HBPW’s Water Reclamation Facility (WRF).

At the Holland Water Treatment Plant, HBPW tested for PFAS compounds in the water before and after treatment. Both samples came back as non-detect (<2 parts per trillion) for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA).  The Environmental Protection Agency’s (EPA) health advisory level for PFOA and PFOS is 70 parts per trillion (ppt).

The Michigan Department of Environmental Quality (MDEQ) is currently undertaking an effort to test all community water supplies in the state of Michigan. Their efforts to date have included most of the supplies in the counties surrounding Ottawa County, but they have not yet tested Holland or other Ottawa County water supplies. In order to get information to the community sooner, HBPW chose to take a proactive approach and start the testing process early.

“HBPW has been providing water to the Holland area for 125 years,” said Dave Koster, general manager, HBPW. “Taking a proactive approach to testing for PFAS was important to us in an effort to continue to provide open, transparent information to our customers. Customers have the right to clean water and we are proud that we can provide that to our community,” said Koster.

In addition to testing the drinking water, HBPW also tested the treated water from the WRF. The WRF provides treatment of wastewater from the City of Holland and surrounding townships. The test results from the WRF were also very low, with the effluent water sample having a PFOS concentration of 2.61 parts per trillion (ppt) and a PFOA concentration that was non-detect.

Additionally, water from the facility’s biosolids was tested and had a non-detect for PFOS and a concentration of 2.06 ppt for PFOA. These levels are all well below the MDEQ water quality standards for discharges from wastewater treatment facilities and are also well below the 70 ppt drinking water standard.

Moving forward, HBPW plans to continue to self-monitor for PFAS in both drinking water and the effluent water from the WRF. Additionally, HBPW staff will work closely with the MDEQ on their future sampling efforts at the facilities. Should any concerns arise from this future testing, HBPW will immediately share those results with the community.
