Rothbury Residential Well Sampling (Rothbury, Oceana County)

• In late-September 2020, EGLE's contractor, Fleis & Vandenbrink, sampled six residential drinking water wells in the vicinity of the Greenlawn Mobile Home Court at homes where EGLE had received permission for sampling. Of the six homes sampled, two exceeded one or more PFAS Part 201 groundwater cleanup criteria for drinking water, meaning, they exceeded either 8 ppt PFOA or 16 ppt PFOS. The District Health Department #10 immediately provided bottled water to these homes and, as of October 2020, was arranging installation of point-of-use filters.
• On October 27, 2020, EGLE's contractor sampled five additional residential drinking water wells in the area.  Of these five homes sampled, two homes exceeded one or more PFAS Part 201 groundwater cleanup criteria for drinking water. The District Health Department #10 immediately provided bottled water to these homes and, as of November 2020, is arranging installation of point-of-use filters.
• On November 12, 2020 EGLE's contractor sampled two additional residential drinking water wells in the sample area. Neither of the two samples had detections of PFAS above Part 201 groundwater cleanup criteria for drinking water.
• On December 9, 2020, EGLE hosted a virtual public information meeting to provide information to the community of the status of this investigation area.
  • Rothbury Residential Well Sampling Informational Meeting.

• In February 2021, EGLE sampled the drinking well water at six residences and four non-residential properties. Of the ten wells sampled, one had a detection of a PFAS compound above Part 201 groundwater cleanup criteria for drinking water.
• In March 2021, EGLE sampled the drinking water wells at seven residences and one non-residential property. Of the eight wells sampled, one had a detection of PFAS compounds above groundwater cleanup criteria for drinking water.
• Based upon the results of the July 2021 sampling, EGLE expanded the sample area in August 2021 to include 10 additional homes, the majority of which were located south of the previous sample boundary.
• In late-August and September 2021, EGLE sampled the drinking water wells at five homes in the sample expansion area. None of the five drinking water wells sampled had detections of PFAS above criteria.

• In the summer of 2023, EGLE drilled deep drinking water wells to provide a new water supply to 12 homes and the Village of Rothbury building, which previously had elevated levels of PFAS in their well water. This provided a clean water supply to all the homes in the sample area known to have had elevated levels of PFAS in their old drinking water wells.
