Madison Water Utility announced Friday crews will start pumping water from Well 8 into the distribution system on an as-needed basis.

The well has been in standby mode since mid-June, and its water has been tested regularly for safety and quality, officials said.

Well 8 is a seasonal well that is generally used in the hot, dry summer months to meet increased demand, according to a release. Not only was July dryer than normal, but two other wells in the area are out of service -- one for reconstruction and one for repair.

The well will be used for the next couple of weeks to help provide enough supply and fire protection for homes and businesses on the east side, officials said.

Well 8 was the focus of concern for residents after a chemical called PCE was found in shallow groundwater at nearby Madison Kipp Corporation, but no PCE has ever been found in the water at Well 8, according to the release. It is extremely unlikely that running the well over the summer will draw contamination into the well.

Officials said the contamination is in the upper aquifer, but Well 8 is much deeper and draws water primarily from the lower aquifer below a natural barrier known as the Eau Claire Shale.

MWU officials will increase monitoring and work with the DNR to make sure PCE contamination does not enter city water while Well 8 is in use, according to the release.
