Health department says water is OK
Woodbury Minnesota 8420 City Centre Drive 55125

Last Thursday, the Minnesota Department of Health announced it has established a health based value for perfluorobutanoic acid (PFBA), a 3M-manufactured chemical found last year in Woodbury drinking water and in drinking water of several neighboring east metro communities.

The MDH has established the health based value (HBV) of PFBA at seven parts per billion, which, according to health department officials, means the levels measured in Woodbury and its neighboring communities are well below the maximum level allowed before it poses an immediate or long-term health risk.

The announcement of the official HBV comes almost a year after the MDH officials posed a drinking water guideline for PFBA contaminated water at one part per billion.

The amount of PFBA detected in Woodbury municipal wells in 2007 ranged from .07 to .55 parts per billion, with the average amount being .25 parts per billion.

A health based value is the calculated concentration of a groundwater contaminant, or a mixture of contaminants, that poses little or no risk to health, even if consumed daily over a lifetime, a Department of Health report stated.

The measured levels of PFBA in Woodbury water is well below the announced HBV for the chemical.

Department of Health officials met with Woodbury officials to inform the city of the results Thursday morning. Mayor Bill Hargis said the news was reassuring, but not an end to the issue.

"(The announced HBV) is good news, because it means it's at safe levels according to the health department," Hargis said. "But we'd just as soon have the contaminants taken out."

Hargis said the city will continue to urge the Minnesota Pollution Control Agency to monitor the clean up of the former 3M dumpsite located in southeast Woodbury.

An HBV is one consideration used by state groundwater and environmental protection programs to make decisions and recommendations about groundwater contamination.

The established HBV for PFBA indicates the health risk is significantly lower than the preliminary drinking water

Upon the news of the established HBV for PFBA, the health department officials have set up public meetings in the affected communities to be held in March.
