The City of Chico is responding to a claim that the water from a spigot at the alternative homeless campsite on Cohasset and Eaton Roads tested positive for coliform. Reports from the camp say an independent test of the water supply found bacteria, including E. coli and Shigella. City offcials believe the person who tested the sample may have had the seample from the unclean spigot and not the water . Authorities with Cal Water say the water is safe and clean. Public Works staff is working with lab partners to take a sample of the water from the spigot at the site.
