Bell Water Hardness & Quality Report (2026)

Bell, California, in Los Angeles County — a small southeast Los Angeles County city in the Gateway Cities corridor (Bell gained national notoriety in 2010 for the Bell municipal corruption scandal — city officials were found to have paid themselves extremely high salaries and engaged in significant financial misconduct, leading to multiple criminal convictions and major municipal reforms; the case became a landmark in municipal governance accountability), a diverse and densely populated southeast Los Angeles County community with a predominantly Latino-American and Mexican-American population (Bell is one of the most densely populated cities in the US with one of the highest Latino-American percentages in California), and part of the southeast Los Angeles County industrial and working-class suburban corridor — draws its municipal water supply from the Central Basin Municipal Water District via the City of Bell Water Division. Water hardness in Bell measures 171 mg/L — classified as hard.

Bell's hard supply reflects the southeast Los Angeles County Central Basin groundwater and MWD import blend characteristics. The Central Basin at Bell–southeast LA County draws from: the Quaternary Los Angeles Basin alluvial aquifer (calcareous-moderate, partially recharged from MWD import spreading); and the MWD Colorado River import (the Colorado River at approximately 280–320 mg/L, blended with softer SWP supply). The Central Basin blend and City of Bell distribution produce the hard 171 mg/L.

At 171 mg/L, Bell residents encounter regular hard water scale. Monthly descaling with citric acid solution is recommended. City of Bell Water Division consistently delivers water meeting all California State Water Board and EPA Safe Drinking Water Act requirements.
