Morton Paint Company <br /> April 30, 1987 <br /> the site will be calibrated and conditions for alarm <br /> activation will be tested to assure proper system <br /> operation. <br /> ' SOIL SAMPLING AND MONITORING WELL INSTALLATION <br /> Soil samples will be obtained from the native soil beneath <br /> ' the tank pit at each of the vapor monitoring points. A truck <br /> mounted hollow stem drill rig will be used to collect the soil <br /> ' samples. The soil samples will be analyzed using EPA Method 8240 <br /> with additional parameters for MEK, PMA, and Acetone. <br /> The hollow stem drill rig will also be used to drill and <br /> install four groundwater monitoring wells . The wells will be <br /> drilled to a maximum depth of 60 feet . Soil samples will be <br /> obtained at 5 feet intervals and field inspected using an HNU <br /> photo-ionization detector (PID ) . Two soil samples from each soil <br /> boring will be analyzed based on the above mentioned parameter, <br /> ' all other soil samples will be frozen for analysis , if <br /> requested. The wells will be constructed of . 020 inch slotted, 2 <br /> inch diameter PVC well screen and blank casing, clean, washed #2 <br /> Monterey sand will be used as a sand pack. The wells will be <br /> ' sealed with bentonite and grouted to the surface with cement. <br /> (See Appendix 3 for typical monitoring well construction) . The <br /> newly installed wells will be purged and sampled by removing 4-10 <br /> well casing volumes of water. The water samples will be analyzed <br /> using EPA method 624 with three additional parameters for MEK, <br /> ' PMA and Acetone. A copy of the lab analysis will be supplied to <br /> Morton Paint Company. <br /> ' 5 <br />
