Beryllium
Larchmont Village
NOTE: Larchmont Village purchases water from Westchester Joint Water Works which is required to test for beryllium. Sample information shown below was taken by Westchester Joint Water Works.
Beryllium is a toxic metal that is both naturally occurring and released into the environment from industrial pollution and incineration. Beryllium can damage lungs, bones and the digestive system.

ppb = parts per billion
State and national drinking water standards and health guidelines
EWG Health Guideline 1 ppb
The EWG Health Guideline of 1 ppb for beryllium was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against harm to the stomach and intestines.
EPA Maximum Contaminant
Level (MCL) 4 ppb
The legal limit for beryllium, established in 1992, was based on a toxicity study in laboratory animals published in 1970. This limit does not include any additional consideration of children’s health.
