Details: SUMMARY: Inspected chlorination treatment equipment DETAILS: The disinfection treatment equipment includes an LMI solution feed pump rated at a maximum of 0.42 GPH, and it was set at 10% speed and 30% stroke. A chlorine residual of 0.5 mg/l was measured at the treated water sample tap. A routine coliform sample taken at the kitchen was TC negative, and a raw water sample directly from the well was TC positive. The school plans to have the well bore inspected with a camera, and will contact Mike Holladay, engineer to review well construction and treatment options.
