The USAF Occupational and Environmental Health Laboratory conducted an on site wastewater treatment plant evaluation survey at Otis Air National Guard Base from 16-21 Mar 84. The survey was requested because the base is negotiating a National Pollutant Discharge Elimination System (NPDES) permit with the State of Massachusetts, Division of Water Pollution Control. Data was needed to show the current operating efficiency of the plant. Specific concerns of the base were disinfection of the effluent and plant removal of nutrients such as nitrogen and phosphorus. Results of the survey indicate that the plant is able to meet current effluent limitation except for total coliform bacteria. However, future limitation which will include forms of nitrogen may not be met during the winter months when low temperatures adversely affects oxidation of nitrogen. Recommendations were made to: (1) provide a contact chlorination tank for adequate disinfection; and (2) consider methods to increase the organic content of wastewater reaching the trickling filter.

A Problem Confirmation Study was performed at seven sites on Otis Air National Guard Base: the Current and Former Training Areas, the Base Landfill, the Nondestructive Inspection Laboratory, the Fuel Test Dump Site, the Railyard Fuel Pumping Station, and the Petrol Fuel Storage Area. The field investigation was conducted in two stages, in November 1983 through January 1984, and in October through December 1984. Resampling was performed at selected locations in April and July 1985. A total of 11 monitor wells were installed and sampled and test pit investigations were conducted at six sites. In addition, the contents of a sump tank, and two header pipes for fuel transmission lines were sampled. Analytes included TOC, TOX, cyanide, phenols, Safe Drinking Water metals, pesticides and herbicides, and in the second round, priority pollutant volatile organic compounds and a GC 'fingerprint' scan for fuel products. On the basis of the field work findings, it is concluded that, to date, water quality impacts on groundwater from past activities have been minimal.

The purpose of this task is to determine if environmental contamination has resulted from waste disposal practices at Otis ANGB MA; to provide estimates of the magnitude and extent of contamination, should contamination be found; to identify potential environmental consequences of migrating pollutants; to identify any additional investigations and their attendant costs necessary to identify the magnitude, extent and direction of movement of discovered contaminants. Partial contents: Well and test pit logs; Site safety plan; Laboratory analytical methods and quality assurance; Federal and state drinking water and human health standards applicable in Massachusetts.
