We've updated our water quality report of Fullerton, California to include the most up-to-date information. Our team aggregated data from the City of Fullerton Water System Management, the U.S. Environmental Protection Agency (EPA), as well our own internal data. We cross reference these data with toxicity studies in scientific and medical literature, and look at upcoming regulatory changes. The water filters that we sell to our customers in Fullerton are optimized with this research in mind.

Source Of Fullerton Drinking Water

Fullerton source water is a mix of both surface and groundwater. Surface water is imported by the Metropolitan Water District of Southern California (MWD), which is a blend of the State Water Project and the Colorado River Aqueduct. The groundwater that Fullerton uses comes from a reservoir under the Prado Dam. 

Lead In Fullerton Drinking Water

Lead enters tap water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. A 90th percentile was not detected in Fullerton drinking water, but older homes built before 1986 still contain lead pipes and plumbing. The EPACDC and The American Academy of Pediatrics all acknowledge that there is no safe level of lead for children.

Chromium 6 In Fullerton Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, Fullerton tap water quality averaged 340 parts per trillion. For the sake of perspective, these levels are nearly 17 times higher than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Fullerton Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. Although these chemicals are not currently regulated very well, the EPA has admitted that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.
