Groundwater sources are monitored for contamination from historical industrial activities and require treatment before distribution.
LADWP uses conventional filtration with coagulation, sedimentation, and sand filtration to remove particles and turbidity from source water.

Dallas's water meets EPA standards for safety. The Los Angeles Department of Water and Power (LADWP) treats and tests water regularly. However, some residents may prefer additional filtration for taste or extra protection, especially in older buildings with lead plumbing.
Dallas receives water from the LA Aqueduct (Eastern Sierra Nevada), State Water Project (Northern California), and Colorado River Aqueduct, plus local groundwater sources from the San Fernando Valley basin.
The primary contaminants detected are disinfection byproducts (TTHMs and HAA5) from the chlorination process. Lead may be present in homes with old plumbing. All levels are within EPA safety standards.
While not required, a water filter can improve taste and provide extra protection. If you live in an older building, consider a filter certified to remove lead. For general use, a carbon filter removes chlorine taste and many organic compounds.
