This is a laboratory analytical results file containing comprehensive environmental testing data for four composite soil samples collected from Newark Bay, New Jersey, analyzed by Battelle Corporation. The file documents results for project number 180-199521 from samples labeled Composite A through D (sample IDs #20251109-#20251112), with testing performed between December 11, 2025 and January 3, 2026.

The analytical work encompasses extensive contamination screening across multiple EPA methods and New Jersey Department of Environmental Protection (NJDEP) protocols, including volatile organic compounds (8260D), semi-volatile organic compounds (8270E), organochlorine pesticides (8081B), PCBs (8082A), herbicides (8321B), metals via ICP-MS (EPA 6020B), hexavalent chromium (7196A), mercury (7471B), cyanide (9014), and petroleum hydrocarbons (NJDEP EPH). Results indicate the presence of contaminants of concern including chromium (ranging 52-70 mg/Kg), manganese (650-950 mg/Kg), lead (70-93 mg/Kg), copper (59-87 mg/Kg), PAHs such as benzo[a]pyrene (150-360 ug/Kg), and PCB congeners PCB-1248 and PCB-1260 at quantifiable levels across multiple samples. Most volatile and many semi-volatile organic compounds were reported as non-detect (indicated by "U" qualifier). The data quality indicators show acceptable surrogate recoveries and method detection limits appropriate for environmental assessment purposes, supporting evaluation of dredged material characterization for the Newark Bay Federal Navigation Channel maintenance dredging project.
