Concord, NH – The New Hampshire Department of Health and Human Services (DHHS) today announced a program to assess potential exposure to perfluorochemicals (PFCs) among Merrimack Village District Water Works (MVD) customers. DHHS, at the request of Merrimack town administrators and in coordination with the Governor’s office, is conducting a limited community exposure assessment by testing blood (serum) of 200 randomly selected MVD customers.

The MVD Community Exposure Assessment will assess approximate levels of human PFOA and PFOS exposure in the community which may be associated with drinking water consumption. The MVD public water system is supplied by multiple individual wells which are combined prior to delivery of residential drinking water. There is known PFC contamination in some groundwater wells that feed the MVD system and in neighboring private wells. At this time, MVD water supply wells are monitored for PFCs and concentrations are below the Environmental Protection Agency Health Advisory Level of 70 parts per trillion (ppt).

“The Department understands the concerns expressed by the community, and we have developed this PFC sampling program to help assess MVD customers’ exposure to PFCs,” said Dr. Benjamin Chan, New Hampshire State Epidemiologist. “The blood testing will provide more information to the Department and residents in the community about potential levels of exposure to PFCs among MVD customers.”

Randomly selected households will be mailed a letter beginning the week of October 3rd to offer them the chance to participate by filling out a questionnaire and then having their blood drawn for testing. There is no charge to the residents for this program. Once 200 people have registered, they will be sent a requisition form and instructions on how to get their blood drawn. All participants will receive a copy of their individual results in the mail. A summary of the community’s results will be shared with participants and with the public. The results can be compared with other tested populations, including the general U.S. population, other communities tested in New Hampshire, and other communities of concern around the country.
