For months, the regional system has been battling algae in the lake that has caused unpleasant taste and odor in the drinking water. Water system officials have maintained that the water remains safe to drink and that the Upstate algae they are dealing with is not one of the toxic varieties that officials have encountered in other parts of the country.
In late June, Upstate water system officials added powdered carbon to their treatment processes to combat the earthy smell and taste from the algae. Just hours later, in an unrelated development, the 45-year-old pipe that drew water out of
"While the treated water has at all times met the standards for safe consumption, maintaining aesthetic quality has been an ongoing challenge," said a statement issued Tuesday on behalf of the water system.
The regional water system serves multiple cities and towns, including
"After analyzing the existing measures that are in place and conducting initial field investigations, it was determined a well-planned and precise application of algaecides is the best near-term option," water system officials said in Tuesday's prepared statement.
Water system officials say the goal of the pilot treatment is to determine how well, and how economically, they can reduce the presence of odor-causing compounds in the lake. The compounds, commonly called geosmin and MIB, are produced by algae and cause unpleasant taste and odor. Water system officials want to reduce those compounds in the lake so that they are at more treatable levels once the source water is processed at the regional plant.
The pilot treatment will focus only on the source water surrounding the regional water system's intake and will not be a treatment of all of
The treatment will be done under the guidance of

The materials used in the treatment have been shown to cause no measurable harm to fisheries, water system officials said.
