4 Introduction LEW Corporation was contracted by Ridgefield Park School District to test for the presence of lead in drinking water in three schools in the district. Sampling Methodology LEW Corporation followed the July 13, 2016 amendments to NJAC 6A:26. Full details on sampling practices can be found in Districts Sampling Plan. All samples were collected in 250mL wide mouth plastic containers that was prepackaged by the analytical laboratory. The sample containers may contain nitric acid, if expedited analysis is required. If not, nitric acid will be added to each sample upon arrival at the laboratory. At each sample location, the first draw sample was taken after it was determined that the water had been standing in the plumbing system for greater than eight hours but less than forty-eight hours. If second draw samples were collected, they were collecting following a flushing protocol outlined in the District s Sampling Plan.

5 Drinking Water Results On September 19, 2017, LEW Corporation collected the following number of water samples: Lincoln Elementary 1 second draw sample collected + 1 quality control sample collected 0 samples above the 15ppb action level Roosevelt School 1 second draw sample collected + 1 quality control sample collected 0 samples above the 15ppb action level Junior Senior High School 3 second draw samples collected + 1 quality control sample collected 1 first draw sample collected 1 sample above the 15ppb action level The complete list of samples that exceeded the 15ppb limit can be found in Appendix A. The complete list of all sample results can be found in Appendix C. The laboratory results can be found in Appendix E. Certain outlets could not or were not tested due to various reasons. The following table lists those locations and the reason why samples were not collected. School Sample Location Reason for not testing. None Recommendations Those outlets where the first draw sample tested below 15ppb are not considered to be elevated and no mitigation is necessary. For those outlets where the first draw sample exceeds 15ppb the following steps are recommended: 1) Immediately discontinue use of the outlets. 2) Conduct second draw (flush) samples on these outlets to further delineate source of contamination. For those outlets where the first draw sample exceeds 15ppb and the second draw sample does not exceed 15ppb, the outlet is contributing lead to the drinking water and very little lead is being picked up upstream of the outlet in the building plumbing. LEW Corporation recommends immediately stopping use of these outlets. LEW Corporation then recommends replacing the outlet and associated plumbing up to the wall connection.

6 For those outlets where the first draw sample exceeds 15pbb and the second draw sample exceeds 15ppb or more, the outlet and the building plumbing are contributing lead to the drinking water. LEW Corporation recommends immediately stopping use of these outlets. LEW Corporation then recommends replacing the outlet and associated plumbing up to the wall connection, and installing a lead filter at the wall connection. A filter maintenance plan will need to be implemented, in order to ensure that all filters are in proper working order. A complete list of recommendations per outlet can be found in Appendix B. Additional Recommendations 1) Follow-up samples should be collected after any remediation efforts in order to determine the efficacy of the work. 2) Any of the inoperable/non-functioning outlets listed above that are brought back into service should be sample. 3) Comply with all requirements set forth in NJAC 6A:26.
