Since 2012 access to safe, clean, and affordable drinking water has been recognized as a human right in the state of california. Federal regulations require community water systems to have regular testing for contaminants that are known to cause cancer, birth defects, or other reproductive harm.
(CDPH) is responsible for administering the Safe Drinking Water Act (SDWA). below)
- The sdwa requires public water utilities to test their water for lead
- Arsenic
- Cadmium
- Boron
- Copper
- Lead-based paint
- Mercury
- Manganese
- Nickel
- Selenium
polychlorinated biphenyls (PCBs)
In addition, the California Public Utilities Commission (CPUC) administers the State Water Resources Control Board’s (SWRCB’s) water quality standards. CPUC’s standards are based on the U.S. Environmental Protection Agency’s Lead and Copper Rule (LCR), which was adopted in 1978.
LCR, public utilities must reduce lead and copper levels in their service lines to 15 parts per billion (ppb) or less by 2015. For more information, please visit www.swrcb.ca.gov/lead-and-copper.

Where does LA tap water come from?
The water in the City of Los Angeles comes from the local area, treated State Water Project water, and imported water from the City of San Diego. The city’s water supply is regulated by California’s Department of Water Resources (DWR) and the California Public Utilities Commission (CPUC).
DWR regulates the amount of water the city can draw from its aquifer. CPUC regulates how much water can be pumped out of the San Joaquin River Basin, which includes the cities of Sacramento, Stockton, Fresno, Bakersfield, Merced, Modesto, San Bernardino, Tulare and Imperial counties.
Is LA water hard or soft?
California water is very hard. The state’s most populous city and the second most populous city in the US, Los Angeles, has a water hardness average of 127 PPM, while San Francisco has a hard water level of 100PPA. California is the only state that does not have a standard for the hardness of its water.
Instead, the state uses a “hardness standard” that is based on the amount of dissolved solids in water, which is measured in parts per million (ppm). The hardness standard is set by the California Department of Water Resources (DWR) and is used to determine how much water a person can drink or bathe in. It is also used as the basis for water quality standards for drinking water in California.
Where is the best tap water in the US?
In the world, missouri has some of the best drinking water. In the last eight years, the city of Independence has been named among the top five best-tasting tap waters in the world seven times. The state of Mississippi is home to the largest concentration of freshwater lakes and rivers in North America. River, which flows through the state, is the second-largest river in America, after the Colorado River.
Is there chlorine in Los Angeles tap water?
Disinfectants like chlorine are added to the tap water. EWG guidelines suggest 0.1ppb or less; LA’s levels are 10.5ppb; the legal limit is 60 ppb. According to the U.S. Centers for Disease Control and Prevention, the national average is 17.2 parts per million.
“We’re not ing that the water is safe to drink, but we’re ing it’s not harmful to your health,” said Dr. Michael Hansen, a professor of environmental health sciences at the University of California, San Francisco, who was not involved in the study.
How long before LA runs out of water?
Nasa predicts that california only has enough water to last one year. Times released an op-ed piece by Jay Famiglietti, a water scientist at NASA. “California’s drought is the worst it’s been in more than half a century,” he wrote. “The state’s reservoirs are at historic lows, and the snowpack in the Sierra Nevada is at its lowest level since record-keeping began in 1895.
The state is in danger of running out of water before the end of the year, if it doesn’t do something about it soon.” California is currently in its fourth year of a historic drought, which is expected to continue for at least another two years.
According to the National Oceanic and Atmospheric Administration’s (NOAA) National Drought Mitigation Center (NDMC), the state has experienced its driest four-year period on record, with the average annual precipitation falling by an average of 1.5 inches (4 centimeters) since the beginning of 2013. This year has already been the wettest year in California’s recorded history, the NDMC reports.
