HOLLIS, NH -- The Natural Stone Council (NSC) recently announced their unequivocal support for granite as a safe, natural material for use indoors based on prior research and, most recently, both an independent study funded by NSC member, the Marble Institute of America (MIA), and newly issued U.S. Environmental Protection Agency (EPA) statements reaffirming that granite poses no health risk.

On Friday, July 25, 2008, the EPA released new statements asserting that no credible evidence exists to suggest that granite countertops pose any safety threat. Citing its own assessment of various studies the agency statement said, in part, the "EPA has no reliable data to conclude that types of granite used in countertops are significantly increasing indoor radon levels."

The statements can be found at the EPA Web site, http://iaq.custhelp.com/cgi-bin/iaq.cfg/php/enduser/std_alp.php. The EPA's statement reflects the findings of a recent study by geochemistry researchers who tested the most popular granites used for kitchen countertops in the U.S. and found that none of the stones posed any health risk.

"Based on the testing results and EPA standards, we can conclude that the most popular granites used as countertop surfaces pose no health threat to homeowners," said L.L. Chyi, a Ph.D. and professor of Geology and Civil Engineering at the University of Akron in Ohio.

The 13 granites that were tested are among the most popular countertop surfaces in the U.S. -- New Venetian Gold, Ubatuba, Santa Cecilia, Tropic Brown, Absolute Black, Tan Brown, Giallo Ornamental, Crema Bordeaux, Baltic Brown, Giallo Veneziano, Dakota Mahogany, China Black and Yellow Star.

"Rumors about the safety of granite have been circulated for years," said John Mattke, Co-Chair of the NSC and Chairman of the NSC's Sustainability Committee. "However, the facts remain the same. There is no credible scientific evidence suggesting that granite countertops pose a significant radon risk."

The NSC does not refute that some types of granite do emit radon gas, but studies have shown that the majority of stones tested generate either unmeasurable or insignificant emissions that are well below the levels requiring EPA-recommended remediation. Moreover, the EPA has repeatedly stated that it has never found any evidence that granite countertops contribute significant amounts of radon to a home. Its statements on Friday apparently came in response to a media-fueled panic resulting from questionable reports suggesting that granite posed a health risk, reports the NSC.

"The rumors and misinformation that persist focus only on igneous stones, like granite, and do not involve stones such as marble, travertine, slate, limestone, soapstone and others," said Mattke. "There is significant evidence to suggest these baseless allegations about granite stem from efforts by some manufacturers of competing countertop materials to increase their own market share by undermining consumer confidence in the safety, beauty and durability of granite."
