1 September, 0 Mr. John Susino Bergen County Special Services School District 0 Farview Avenue, Room 00 Paramus, New Jersey 0 RE: Water Sampling at Filter-Installed Point at the Bleshman Building, Bergen County Special Services School District CHA Project No Dear Mr. Susino: In accordance with the Scope of Services outlined in our EWA #-revised, CHA conducted sampling and analysis for lead for one drinking water sample at one Special Services District building. The results of this sampling are presented below. Scope In an effort to evaluate the efficiency of the installation of filters at drinking fountains, kitchen sinks, and/or nurse s office sinks, the Special Services District initially installed one filter on a nurse s office sink that was previously identified to exhibit first draw and flush sample lead levels elevated above the lead action level of ppb. The location at which the filter was installed is at the Paramus Campus in the Bleshman Building, in the nurse s office sink on the left side of room upon entering. The previous first draw sample results were ppb and flush results were. ppb. The filter unit that was installed was reported by the District to be a M Aqua-Pure model MFF. Field Activities On September, 0, CHA collected first draw and flush samples from the identified end-use point. The samples were submitted to TestAmerica, Inc. located in Buffalo, New York on September nd following proper chain-of-custody procedures. The samples were submitted for the analysis of lead via EPA Method 00. under a two-day deliverable schedule. The first draw sample was logged for analysis and the flush sample was placed on hold pending the first draw results. Findings and Conclusions The laboratory results for the first draw sample reported a lead level of. ppb and therefore the flush sample was not analyzed. This concentration represents a significant decrease from the

2 Mr. John Susino September, 0 Bergen County Special Services School District Page concentration of ppb detected during the earlier sampling event prior to the installation of the filter system. Based on this result, the filter system installed at this end-use point is effective in reducing the lead level in the water drawn from this point to below the lead action level of ppb. Should you have any questions, please do not hesitate to contact me at () -. Sincerely, Seth H. Fowler, CHMM Associate Vice President
