NJ0809001 Results of PFOA and PFOS Analysis /V Dear On February 9, 2007, representatives of the New Jersey Department of Environmental Protection, Bureau of Safe Drinking Water (NJDEP- BSDW) collected samples at your facility. The samples were collected as part of a study to determine the general occurrence of Perfluorooctanoic Acid (PFOA) in wells and surface waters, which are a source of drinking water, throughout the Slate. Raw water samples were collected at WL001004 (Well #2B Ranney wellfield), WL001005 (Well #3A Ranney wellfield) and WL002009 (Well #2 - Layton weJlfield). STL Laboratories in Denver Colorado analyzed the sample for PFOA and PFOS (Perfluorooctanoic Sulfonate). This laboratory is certified for the conduct of these measurements by NJDEP. The results o f the analysis from vour facilitv showed the following: * *> C? WL001004 Well #2B Compound Concentration (ppb*i PFOA 0.066 PFOS 0.0026 J WL001005. Well #3A Compound Concentration (nob*!

Well #2 Compound Concentration fppb*l PFOA 0.083 PFOS 0.0029 J *- In terms of concentration ppb refers to parts per billion J- Estimated value The results o f a trip blank conducted along with these samples was non detectable for both parameters. On February 13, 2007 NJDEP released the results of a study that evaluated the occurrence of PFOA in drinking-water systems throughout the state. The study showed very low levels in wells throughout New Jersey, consistent with levels found in your system and other areas of the country. DEP also has also developed a preliminary drinking water guidance value for PFOA of 0.04 ppb. The new guidance level is the first phase of an ongoing process that could establish a drinking-water standard for this contaminant. As the science regarding PFOA is developing rapidly, NJDEP will continue to conduct sampling and evaluate data from all sources as it becomes available. NJDEP is not recommending a change in consumption patterns based on the new information. Both the report and the guidance value document are available on the NJDEP's website at http://www.ni.gov/dep/watersupplv/pfoa.htoi. The data collected from your facility will be used to determine the extent of future monitoring and regulation of these substances in drinking water. Additional information on PFOA can be found on USEPA's website at http://www.epa.gov/opptintr/pfoa/index.htm. If you have any questions on this matter, please contact Betty Jane Boros-Russo of my staff at (609) 292-5550. When contacting the Department please reference the PWSID No. NJ0809001 and Letter No. WLT070001. * Sincerely Water Supply Operations cc: Betty Jane Boros-Russo, BSDW Karen Fell, BSDW Felicia Fieo, BSDW Southern Bureau of Water Compliance and Enforcement N JrM S\sd_blank_ktier DEP2-SDWB-000497
