Return to compliance on DBPs
Lake Alpine Water System has returned to compliance and samples are below the Maximum Contaminant Level (MCL) for the disinfection byproducts (DBP) of Haloacetic Acids (HAA) and Trihalomethanes (TTHM). This is a customer notice with GOOD news!
The two granular activated carbon (GAC) filters are working well at reducing organics, the precursors for disinfection byproducts. As a result, we are back in compliance with low levels of HAA and TTHM. The decreasing trend is great news for your water quality, and we are preparing for our GAC filter renovations scheduled for September 2023.
