Fluoridation Chemicals May Exceed EPA Arsenic MCL Levels

NSF is a non-for-profit product standards organization. They suggest standards for fluoridation chemicals classified as ANSI/NSF Standard 60, Drinking Water Treatment Chemicals.

In response to a letter of inquiry by the State of Florida, Department of Public Health, inquiring about the amount of heavy metals in fluoridation chemicals, NSF sent a letter, dated April 24, 2000, stating the following

"The results in Table 1 indicate that the most common contaminant in these products [fluoridated water] is Arsenic.. The U.S. EPA recently proposed lowering the maximul MCL (Maximum Contaminent Level) from 50 ppb to 5 ppb. The end results is that future tests of fluoridation chemicals may result in increased product failures [drinking water exceeding maximum Arsenic levels] when the lower Arsenic MCL of 5 ppb is promulgated."

"Other significant contanimants found.. is Lead"
