The North Collier Regional Water Treatment Plant is a membrane softening plant. In membrane softening treatment the water is separated into two streams, a finished water product called a permeate and a waste stream called the concentrate. The waste stream is disposed by a method called deep well injection. The waste or concentrate stream and its effect on the ground water surrounding the injection well is closely monitored by laboratory personnel. Samples are collected from two monitoring wells located near the injection well. The following analysis is performed on the monitoring wells; as well as, the concentrate stream: pH, temperature, Conductivity, Chloride, Sulfate, Total Dissolved Solids, Total Kjeldahl Nitrogen, Sodium, Fluoride, Gross Alpha, Radium 226 &228. The analysis results are reported to the Florida Department of Environmental Protection.
