This data is summary data. Please see Exceedances of Primary Maximum Contaminant Levels (MCLs) by Public Drinking Water Systems (2012-2017) for more detail.
Population data from LA County Department of Finance

Data includes violations of maximum contaminant levels (MCLs) for primary drinking water contaminants in public water systems in LA County from 2012 to 2017, as listed in the Annual Compliance Reports published by the SWRCB. For 2012 and 2013, this was published by the DPH. Data on secondary MCL violations is not available. In some cases, the same violation is listed multiple times on the ACR due to responsive actions being reported via separate listings; the number of violations were identified using the unique violation identification number and compliance period dates to avoid duplicative counting.

Grades, beach location and analysis from Heal the Bay's Beach Report Card was used (2013-2018), which uses a 12-month grading period from April to March. Seasonal patterns of the most recent year’s grades (2017-2018), as well as trends over the last five years were used. As defined in Assembly Bill 411 in California, the summer dry grading period is from April through October. The winter dry weather grading period is from November through March. The year-round wet weather conditions are graded from April through March. Values may not add up to exactly 100% due to rounding.

*** Water Use Grouping
Total MI Demand - Total consumptive demand or water used to meet municipal and industrial demands.
Potable Consumptive Demand (20x2020) - Demand used for calculating per capita water use for complying with SB x7-7 that excludes recycled water use. Recycled water is a part of water-use efficiency.
Total Demand - Total water use that includes municipal and industrial, agricultural, seawater barrier, and groundwater replenishment.
