Medications making their way into drinking water a concern for scientists.

STANDISH, Maine (NEWS CENTER) -- With roughly a trillion gallons of water, it is hard to believe that one pill, or even an entire bottle of them, could have an impact on the water quality of Sebago Lake, but think again.

"We are concerned about all contaminants that could possibly enter Sebago Lake, and subsequently the water supply," explained Michael Koza, the lab manager at the Portland Water District.

Koza says Sebago Lake, the drinking water source for nearly 200,000 people, is clean and pristine, but that doesn't mean they haven't detected minuscule amounts of medications and other contaminants.

The Portland Water District is now treating its water with a hi-tech UV light system.

STANDISH, Maine (NEWS CENTER) -- The Portland Water District recently completed installation of a hi-tech safeguard against potential contaminates in its water.

"Each of these reactors is configured up to 52 million gallons of water a day," stated Joel Anderson, chief operator of the Sebago Lake Water Treatment Facility, as he showed of the district's two new UV reactors.

These massive tubes are designed to keep microorganisms out of the district's drinking water.

"How UV works is that it actually penetrates the cell of an organism and disrupts the organism's DNA so that it can no longer replicate," explained Anderson.

The process keeps any microorganisms like cryptosporidium or giardia that pass through from being able to multiply and make people sick.
