LET’S MAKE SENSE OF YOUR WATER!

Los Angeles-City (LADWP) Water Quality Report

DID YOU KNOW water quality reports, also known as “Consumer Confidence Reports (CCRs),” are annual documents that all public water systems are required to provide to you via mail and online. These reports are supposed to provide important information about the quality of the drinking water delivered over the previous year.

They can be difficult to read or understand. They are often many pages long and contain complex tables and charts. Culligan Water wants to change this and help you MAKE SENSE OF YOUR WATER.

This easy-to-read report will provide you with the following:

  • Violations: Any federal, state, or local violations your water system has committed recently.
  • Items of interest: Common water issues discussed within your community.
  • Potential concerns: Unregulated contaminants that could be a health concern to you or your family.
  • Water hardness: The current level of hard water in your area.

The Water Quality Report Legend:

  • Health Concern Contaminants that have known health effects that the EPA regulates to protect public health.
  • Aesthetic Issue Not necessarily a health risk but can affect your water’s appearance, taste, or odor.
  • Unregulated Possible health risk but NO standards set by the EPA. Emerging chemicals and compounds the EPA is gathering data on.

Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water.
Action Level (AL): The concentration of a contaminant that triggers additional action.
Public Health Goal (PHG): The level of a contaminant in drinking water that doesn’t pose a significant risk to health. PHG’s are NOT regulatory standards, and may not be attainable due to current remediation technologies.
