Benton County Water Quality Philomath High School senior class project that monitors water quality of swimming holes. Includes photos of the sites and water quality results.We want to make sure that readers know the Benton County Health Department is not endorsing any of the local rivers our lakes as safe to swim in. Benton County Environmental Health regulates public swimming pools. Owners are required to close the pools if there are any safety hazards, if there is not enough residual chlorination or if the water becomes too cloudy.
