Multi-Pure Products Effective at Reducing Levels of Chromium VI in Water

New report of contaminant�s widespread presence raises public drinking water concern.

Las Vegas, NV, December 21, 2010: Millions of Americans are at potential risk from Chromium VI
contamination in their drinking water. Homeowners can protect themselves from the contaminant with a
Multi-Pure drinking water system. New reports from the Washington Post and the Environmental Working
Group (EWG) indicate the suspected carcinogen is more widespread than previously thought � appearing
in the drinking water of 31 major cities across the US. Chromium six (Cr (VI), hexavalent chromium) is a metal
species that is capable of causing cancers in laboratory animals and is considered by the US Environmental
Protection Agency (EPA) a likely a human carcinogen. Multi-Pure International is the manufacturer of
home drinking water systems which are certified by NSF International to reduce levels of hexavalent
chromium.

Cities found to have the highest concentrations of hexavalent chromium are Riverside, CA, Norman, OK,
and Honolulu, HI. The full list of cities where the contaminant has been detected can be found in the EWG
report at www.EWG.org.

Despite mounting evidence of its toxic effects, the EPA has not set a legal limit for hexavalent chromium in
tap water nationally and does not require water utilities to test for it. According to the Post, the state of
California has taken the first steps in limiting the amount of the contaminant in drinking water by proposing
a �public health goal� for safe levels of 0.06 parts per billion (ppb). Some industry experts indicate this level
may be unrealistically low, citing limitations of the EPA�s analytical methods in detecting such low
concentrations.

Multi-Pure�s models MP750PlusRO and CBTPlusRO are certified by NSF International to reduce levels of
hexavalent chromium by up to 91.3%. Multi-Pure�s Director of Laboratory Services, Andrew Fenwick, PhD,
says the company is working diligently on more solutions, �Multi-Pure will continue to be on the forefront of
this issue, working to develop, quantify, and certify the performance of our products as standards for Cr (VI)
evolve.�
