Surface Water Sample Location Plan
April 18, 2019 – Click the following link to find an updated summary of the surface water testing results reflecting the most recently performed round of sampling (sample date 4/15/19).
All of the 4/15/19 test sample results are below the NJ Drinking Water standard of 5 PPB. Since 10/16/18, our office has secured a total of 78 test sample results. All but 2 of the test sample results were below the NJ Drinking Water Standard. The USEPA (federal) standard for arsenic is 10 PPB. All 78 of the sample test results were below that standard. All test results were submitted to the NJ DEP.
The NJDEP has advised the most appropriate standard for comparison for surface water is the chronic standard of 150 PPB. The highest test result was secured during a rain event on 12/21/18. That result was 9.25 PPB or 6.2% of the surface water standard noted by NJDEP.
