Regulation of 1,4-Dioxane in Drinking Water

摘要

Ahead of the federal regulatory curve, the California Department of Public Health (CDPH) joins other states in the nation in setting recommended notification levels for emerging chemical contaminants in drinking water sources. According to US EPA, 1,4-dioxane is a possible human carcinogen. Due to the chemical's highly soluble nature and frequent presence in the environment, concern of human exposures from groundwater consumption continues to grow. How dangerous is 1,4-dioxane? What is the risk of cancer in exposed populations and is there a way to control the contaminant in our drinking water supplies?
