Sipe w/ WQROS-WaRO. Junior Edwards, the ORC for the facility was also present and provided valuable assistance. The inspection included a review of reporting, monitoring, and O & M records for the facility and a walk through of all the components of the treatment and disposal systems. Reporting and record keeping were found to be complete and accurate. The treatment system appears to be operating adequately. The southern infiltration basin was observed to be almost totally covered by what appeared to be floating algae and the northern infiltration basin continues to have subsurface aquatic vegetation. However, the basins appear to continue to be operating adequately. The facility was found to be in compliance with Permit No. WQ0034880.

The GW monitorina results continue to sometime include elevated concentrations of Ammonia TOC, TDS and Chloride; however, these constituents have been detected at the site at similar concentrations since before the treatment and disposal system began operation. It is suspected that these elevated concentrations may be related to past deposition of dredge spoils at the site. The corresponding effluent concentrations being applied to the infiltration basins are consistently below the GW standards. WaRO - WQROS staff will continue to monitor trends in GW concentrations in the future End Use -Infiltration Yes No NA NE Page 5 of 6 Permit: WO0034880 Owner - Facility: State of North Carolina C/O East Carolina University Inspection Date: 05/16/2019 Inspection Type : Compliance Evaluation Reason for Visit: Routine # Is the application High Rate or Low Rate?
