for groundwater monitoring although a guidance manual will
         contain the specifics. Massachusetts DEQE approves few new
         landfills. Most work involves landfill expansions and
         closures. The monitoring program is designed to obtain
         information on background monitoring and field conditions.
         The-program includes quarterly monitoring for indicator
         parameters, an extended list of inorganic parameters
         (including metals) and the 31 VOCs in the priority pollutant
         list plus acetone, methylethylketone, methylisobutylketone,
         and xylene. After the initial groundwater analysis, a
         priority pollutant screen is performed on a site specific
         basis. The Massachusetts DEQE then sets subsequent
         monitoring requirements based on the results.

         The Connecticut Department of Environmental Protection has
         implemented VOC monitoring, through permit modifications, at
         about 75% of the 120 municipal solid waste facilities that
         monitor groundwater (J. Dziuba, pers. com. 1987). Quarterly
         monitoring of VOCs is usually required at all groundwater
         monitoring points.

         The Ohio Environmental Protection Agency, Division of Solid
         and Hazardous Waste Management reported that some landfills
         are monitored for VOCs through hazardous waste regulations
         and state enforcement actions (T. Krichbaum, pers. com.
         1987). The Illinois Environmental Protection Agency reported
         that some landfills are required to monitor VOCs (H. Chappel,
         pers. com. 1987). The Colorado Department of Health, Waste
         Management Division reported that many selected landfills are
         monitored quarterly for VOCs (K. Mesch, pers. com. 1987).
         The California Waste Management Board reported that selected
         landfills are monitored for VOCs (K. Amundson, pers. com.
         1987). The Washington Department of Ecology monitors VOCs
         primarily under the Superfund program (3. Knudson, P. Kmet,
         pers. com. 1987). The Michigan Department of Natural
         Resources, Groundwater Quality Division has monitored VOCs at
         some older unlined landfills and permeable soil landfills
         (T. Work, pers. com. 1987). The Oklahoma State Department of
         Health, Waste Management Service has conducted 20 scans for
         organics since 1985 (C. Varga, pers. com. 1987). About 35 to
         40% of their landfills have groundwater monitoring.

2. The need to require VOC monitoring on a regular basis for all
    municipal landfills in Wisconsin

    a. What are current solid waste groundwater monitoring
        requirements in Wisconsin?

        VOC Monitoring. At the present time, the proposed Wisconsin
        solid waste rules (NR 508) require background sampling of
