Wastewater Characterization Survey Cavalier Air Station, North Dakota (AFSPC).
1997
Hemenway, Doris A. | Gillen, Jeffery C.
A wastewater characterization survey was conducted at Cavalier Air Station, North Dakota, during the week of 13 to 18 August 1995. The purpose of the survey was to: (1) conduct a baseline characterization of the influent wastewater in the on-site stabilization ponds and (2) to determine source discharge concentrations at specific locations throughout the facility. Special compliance concerns to local environmental officials are the Oil & Grease and Total Petroleum Hydrocarbons (TPH) concentrations entering the waste stabilization ponds and elevated constituents at selected locations throughout the base due to a regulated state effluent permit. A special soil/sediment sample was collected at the outfall of the old washrack.. Recommendations: Under normal conditions, Cavalier Air Station Does not discharge wastewater effluent from the evaporation pond to Willow Creek. In the unlikely event that effluent from the evaporation lagoons are to be diverted or released into Willow Creek tributary system, it is recommended that a grab sample of the effluent be taken without delay. The sample should be analyzed for the NPDES parameters listed in the CAS discharge permit. Based on sampling results the discharge of COD (estimated BOD), oil and grease into the evaporation pond could equal or exceed the maximum daily discharge parameters for CAS NPDES permit. Analysis of the evaporation pond water would simulate the actual concentration being released into Willow Creek.
