VI. RECOMMENDATIONS
Based on the conclusions from this study and the Friedman (1988)
study, we recommend that the BSHWM require solid waste facilities
to do the following.
   A. Establish background VOC levels at all groundwater
      monitoring wells.
   B. Monitor leachate for VOCs annually.
   C. Monitor collection lysimeter samples for VOCs annually.
   D. Monitor selected groundwater points at the following
      frequencies:
           1.  every five years for landfills with
               containment and leachate collection
           2. for landfills without containment and
               1 eachate collection:
                 -annually at landfills with capacities
                 greater than 500,000 cubic yards
                 -biannually at landfills with capacities
                 less than 500,000 cubic yards
           3.  for all landfills, regardless of design,
               waste type, or approval date, where
               inorganic parameters are elevated or where
               VOCs have been detected in groundwater--at
               an increased frequency based on degree
               and extent of contamination.
   E. Monitor for VOCs at an increased frequency (monthly or
      quarterly) at any landfill for a limited time period to
      define contamination or to confirm questionable VOC data.
   F. Continue sampling for inorganic indicator parameters.
   G. When evaluating possible groundwater contamination at a
      landfill, consider increases in chloride above background
      rather than only those values above the secondary drinking-
      water standard or other set standards.
   H. Add the first 6 compounds listed in Table 2B to WDNR's list
      of compounds required for laboratory VOC quantification.
