Environmental Working Group collected tap water contaminant data from 42 states over a two and one half year period. The overwhelming majority of the data we obtained were from utilities, with a much smaller component from the states as a part of special monitoring initiatives. EWG painstakingly pieced these data together, and created a website where the public can access the information free of charge at www.ewg.org/tapwater/.

The Los Angeles Regional Water Quality Control Board (LARWQCB) protects ground and surface water quality in the Los Angeles Region, including the coastal watersheds of Los Angeles and Ventura Counties, along with very small portions of Kern and Santa Barbara Counties.

California Beach Report Card - Welcome to the only comprehensive analysis of coastline water quality in California. Each week, over 350 beaches are graded A to F based on bacteria analysis. Check back often for the latest grades...know before you go!

The California Urban Water Management Planning Act (California Water Code Division 6, Part 2.6 Sections 10610-10656) requires water suppliers to develop water management plans every five years to identify short-term and long-term water resources management measures to meet growing water demands during normal, dry, and multiple-dry years.

LADWP’s Water Plan includes discussion of the following:

1. •A description of existing and planned sources of water available to the water supplier;
   

2. •Conservation efforts to reduce water demand;
   

3. •Activities to develop alternative sources of water;
   

4. •Assessment of reliability and vulnerability of water supply; and
   

5. •Water shortage contingency analysis.

The Water Replenishment District manages groundwater for nearly four million residents in 43 cities of Southern Los Angeles County.

The 420 square mile service area uses about 250,000 acre-feet of groundwater per year taken from the aquifers of the Central Coast and West Coast Basins. This equates to nearly 40% of the total demand for water.

WRD is involved in groundwater monitoring, safe drinking water programs, combating seawater intrusion and groundwater replenishment operations throughout Southern Los Angeles County.

The California Water Environment Association is a nonprofit public benefit corporation that is committed to protecting our water environment through education and training. We invite you to learn more about CWEA-our purpose, member benefits, and structure-as well as the wastewater industry by exploring our web site and our links to partners dedicated to the common goal of water quality.

Consumers waste billions of dollars a year on bottled water even though as much as 40 percent of it comes from the tap in the first place. Bottled water poses serious threats not only to your pocketbook, but also to your health, your community, and the environment.

When a person opens a spigot to draw a glass of water, he or she may be tapping a source close to home or one hundreds of miles away. This website is intended to help Californians identify their source(s) of drinking water, learn more about how drinking water is treated, and learn how to help prevent pollution of our groundwater and surface water supplies.
