The Water Quality Laboratory

Casitas goes beyond what is required by State and Federal Regulations. We monitor the lake, watershed, treatment plant and distribution system above and beyond compliance standards in order to bring you a consistently safe and dependable water supply. Casitas began the monitoring program for microbiological samples in the 1960s and currently analyzes more than 300 extra bacteria samples each year. The supplemental sampling program provides additional assurance that customers in all parts of the distribution system are receiving high quality water. Casitas also tests for Giardia and Cryptosporidum, two microscopic protozoan parasites that can cause problems. The Marion Walker Pressure Filtration system is designed to filter out these parasites.

Casitas also tests regularly for algae, odor, color, pH, temperature, turbidity (suspended material), conductivity, dissolved oxygen and chlorine residual. Additional testing is done after line repairs or replacement and after maintenance on the Marion R. Walker Pressure Filtration Plant. These supplemental sampling programs provide additional assurance that customers in all parts of the distribution system are receiving high quality water.
