Abstract : Personnel for Armstrong Laboratory Water Quality Branch conducted a wastewater characterization survey for 23 SOPS, New Boston Air Station, New Hampshire at the request of 21st AMDS, Peterson Air Force Base, Colorado from 19-26 June 1995. The scope of the survey was to sample wastewater throughout the base to determine if significant pollutant concentrations exist in the wastewater discharge, and at key source facilities. In addition, we addressed the sanitary system wholistically and determined possible sources or processes which were currently impacting the effluent and thus failing the Whole Effluent Toxicity (WET) portion of the NPDES permit. This Wastewater Treatment Facility (WWm has a very low flow and does not discharge to a navigable waterway, and therefore does not allow for dilution for the WET portion of the bioassay as of June 1995. During the survey, we determine that there was insufficient mixing in the chlorination chamber, no dissolved oxygen in the effluent, and need for metered chemical addition for alkalinity control. A pilot continuous aeration mixer was installed during the survey and resolved the chlorine mixing and dissolved oxygen issues. This modification and the continuous vigilance of the operators of the plant to balance the alkalinity have resulted in finally passing the WET portion of the bioassay.
