Two more wells providing drinking water in Nampa have tested positive for E. coli bacteria, which can cause intestinal illnesses.
Southwest District Health tells the Idaho Press-Tribune six previous wells found to be contaminated with E. coli are still testing positive.
Testing of the private wells is voluntary, and the health district isn't releasing the exact locations. Officials say there have been no reports of illnesses connected to the contamination.
The health district first found the contamination in the south end of Nampa in August and says it hopes to have a better idea of the possible source in about a month.
