Arsenic

ID city wants to blend water to reduce arsenic

TWIN FALLS, ID — This city’s drinking water has tested positive for arsenic, with levels as high as 18.1 parts per billion (ppb) in some samples, above the US Environmental Protection Agency’s allowable level of 10 ppb, a June 6 Times-News story said.


A water quality report revealed the amounts last week, although the samples were taken in 2006.


The city said it is working with the state Department of Environmental Quality (DEQ) to reduce the amount of arsenic. The DEQ has given the city until January of 2011 to bring arsenic levels down to 10 ppb. The city wants to blend arsenic-containing water with water from Blue Lakes Springs.

Scientists are concerned with endocrine disruptors, chemical compounds that mimic hormones when they enter the body, the article said.
