Total Dissolved Solids (TDS)
Total dissolved solids (TDS) is measured at Lake Skinner and the Skinner Filtration Plant, where water supplies are a mix of State Water Project (SWP) and Colorado River waters and delivered to the Water Authority. TDS is a function of the proportion of water from each source, with the Colorado River generally having higher TDS than the SWP water. The TDS water quality goal of 500 ppm is a drinking water guideline for taste, color, deposits and staining concerns.
