EWG's Tap Water Database — 2019 UPDATE

Donate

Cedar Village II

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the North Carolina Department of Environment and Natural Resources, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the U.S. EPA (January 2019 - March 2019), tap water provided by this water utility was in compliance with federal health-based drinking water standards.

GUIDELINES

7 Total Contaminants

  • Legal does not necessarily equal safe. Getting a passing grade from the federal government does not mean the water meets the latest health guidelines.
  • Legal limits for contaminants in tap water have not been updated in almost 20 years.
  • The best way to ensure clean tap water is to keep pollution out of source water in the first place.

Legal ≠ Safe

EWG Health Guidelines fill the gap in outdated government standards.

The federal government’s legal limits are not health-protective. The EPA has not set a new tap water standard in almost 20 years, and some standards are more than 40 years old.

DETAILS
X

The cancer-causing pesticide chlordane was banned in 1988. Chlordane is persistent and accumulates in the body. It is still found in the environment and in the bodies of adults and newborn babies.

Chlordane was found at 12 times above EWG's Health Guideline.

Dichloroacetic acid

more about
this contaminant

Dichloroacetic acid, one of the group of five haloacetic acids regulated by federal standards, is formed when chlorine or other disinfectants are used to treat drinking water. Haloacetic acids and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy. Click here to read more about disinfection byproducts.

Dichloroacetic acid was found at 9.7 times above EWG's Health Guideline.

Health Risks

The EWG Health Guideline of 0.7 ppb for dichloroacetic acid was defined by the Environmental Protection Agency as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.
