Respondent violated 40 CFR, section 265.93 (d) (4) , in <br /> that on or about December 6 and 7 , 1988 , Respondent failed to <br /> implement a groundwater quality assessment plan which would <br /> determine the rate and extent of migration and concentration of <br /> hazardous waste or hazardous waste constituents in the <br /> groundwater. Respondent failed to make a sufficient number of <br /> hydraulic conductivity (K) determinations. Respondent has <br /> failed to adequately monitor Pond 1 in the upper water-bearing <br /> zone. Also, Respondent has failed to monitor the interval <br /> between approximately 70 to 180 feet in depth. Additionally, <br /> the lower water-bearing zone (180 to 220 feet) is inadequately <br /> monitored. <br /> 2 . 4 .
