CRAWFORD COUNTY, Mich., (WPBN/WGTU) -- Some of the results for the Grayling Army Airfield water investigation have been released by the Department of Environmental Quality (DEQ), which is in charge of the water testing at this time.

High chemical levels were detected around Camp Grayling and on Lake Margarethe last year.

Water testing is still underway at both locations to determine the severity of the contamination areas.

According to the health department district representing these areas, the results are still coming in, but in batches.

The District Health Department #10 says the following results do not include the investigation around Lake Margarethe in Grayling, which has just begun.

• How many residents tested so far - 588. This number is a combination of the initial testing coordinated through the National Guard Base in Grayling and the Department of Environmental Quality (DEQ) coordination of all residential well testing for the Grayling PFAS water investigation.

• Total Exceedances - 14 - the number of residents that exceed the EPA's lifetime health advisory of 70 parts per trillion (PPT) for PFOA and/or PFOS. PFOA and PFOS are the only two compounds in the PFAS family of chemicals that have a guidance on them. Residents were immediately contacted and provided with bottled drinking water and an NSF-certified filtration system to remove PFAS from the drinking water at no charge to them.

• Total Detection of PFOA/PFOS - 184 - the number of detections of PFOA and/or PFOS detected in wells but below the 70 PPT lifetime health advisory. Residents received an NSF-certified filtration system to remove PFAS from the drinking water at no charge to them.

• Total Detection all other PFAS - 146 - the number of detections of all other PFAS (excluding PFOA/PFOS) detected in residential wells. These other PFAS compounds do not have a health guidance on them from the EPA, but the Michigan Department of Health and Human Services recommends that ANY detection of PFAS in drinking water be filtered with an NSF-certified filtration system provided at no cost to residents until more is known about the source and a permanent solution for remediation is determined.

• Total Non-Detection of PFAS - 244 - the number of residential samples that detected NO PFAS of any kind in the drinking water.

Affected households are getting filtration systems installed in their homes for free.

There is no word yet on additional meetings for water updates for these Crawford County areas.

Nearly half of the places where elevated levels of PFAs were detected across the state are near military installations, such as Camp Grayling and the Combat Readiness Training Center.

The contamination issues in Crawford County and other areas across the state prompted Governor Snyder to approve $23 million in emergency spending last month.
