Wastewater Discharge Sampling and Reporting

Food Manufacturing Facility
Northeast, Massachusetts

Watermark provided wastewater discharge sampling, reporting and permitting services for the facility’s discharge permit compliance program. The project required close coordination with the City’s Publicly Owned Treatment Works (POTW).  Sampling was comprised of both grab and composite samples, utilizing an ISCO Auto Sampler and conducted on a monthly basis in accordance with the requirements set forth in the Industrial User Wastewater Discharge Permit.  Watermark reviewed analytical results and compared them to acceptable discharge concentrations.

wastewaterMonthly reports were prepared on the results of the wastewater sampling and the daily total flow records through both outfalls, as required by the permit. Watermark performed an annual flow meter calibration on the ISCO 4210 Ultrasonic Flow Meters used at 2 locations (Confined Space Entry required) and inspected all installed monitoring equipment for proper operation and functionality.
