DNR discloses sites of tainted wells

Following a Sunshine request by the News-Leader, the Missouri Department of Natural Resources on Friday released the locations of TCE-contaminated wells near Rogersville.

The well with the highest contamination detected so far is located southwest of Rogersville near Farm Road 186.

That well had 323 parts per billion of the chemical degreaser trichloroethylene when it was tested, far higher than the 5 parts per billion the EPA allows for drinking water.

It's also far higher than the 11 other positive TCE well tests, which ranged from 0.63 ppb to 6.22 ppb.

DNR initially declined to reveal the locations of the contaminated wells, out of concern that might deter people from participating in the department's TCE well survey.

At the Rogersville, Missouri TCE contamination site, the location of impacted private wells is being kept private, to anonymize the exact locations of impacted homes. Though to my knowledge there is no vapor intrusion investigation underway in Rogersville, this approach is routinely followed at vapor intrusion investigations across the country, as well. In an editorial today, the Springfield newspaper questioned that practice.

What do you think?



DNR should give locations of wells with TCE

Concerns over property values shouldn't trump the Sunshine Law.

Think of it like a series of burglaries. Or sinkholes. Or lead migrating from an abandoned mine.

If you lived nearby, you'd want to know as much detail as possible about all those problems, wouldn't you?

The state Department of Natural Resources doesn't see it that way.

The agency is refusing to release addresses of several wells near Rogersville -- even though they show the presence of a commonly used degreaser known to cause cancer in certain animals.
