pesticides (EPA methods 8150, 8140, 8080 and 632) . <br /> 47. Page 3-105, Section 3.3.3.5.4.1 <br /> State the chemical components of neutralized battery acid <br /> solutions and photographic laboratory wastes. <br /> State the type of expired and used pharmaceuticals are <br /> thought to be disposed of at this SWMU. <br /> 48 . Page 3-106, Section 3.3.4. 1.1 <br /> State whether the storm drainage lagoons have ever <br /> overflowed. In the 1991 Draft RI/FS Report, soil boring <br /> SB103 just to the north of SWMU No. 4 had elevated metals. <br /> State whether the local drainage system is used for <br /> agricultural and/or recreational activities. <br /> 49 . Page 3-112, Section 3.3.5.5.3. 1 <br /> Explain how the number of additional soil borings (12) was <br /> derived. <br /> 50 . Page 3-114, Section 3.3. 6.2 .1 <br /> State if there are any cracks in the asphalt paved area at <br /> SWMU No. 11. <br /> 51. Page 3-121, Section 3 .3.7.5.4 <br /> State the hazardous components of asphaltic materials and <br /> sheetrock. <br /> If the possibility exists that any burning occurred here, <br /> then dioxins (EPA Method 8280) should also be analytes. <br /> 52 . Page 131, Section 3.3. 10.5.4. 1 <br /> State which metals are present in the road oils as <br /> impurities. <br /> 53 . Page 3-153, Section 3.4. 0 <br /> List all the contaminants, not just PCE and TCE, found in <br /> groundwater along with their maximum concentrations. <br /> 54 . Page 3-158 (Rev. 1) , Section 3. 4.4.2. 1 <br /> The soil samples should be analyzed for the presence of <br /> other contaminants of concern (including SVOCs, metals, and <br /> pesticides) , rather than only halogenated volatile organics <br /> as stated. <br /> 55. Page 3-158, Section 3. 4.4.2 .2 <br /> Pump (aquifer stress) tests should be conducted as well as <br /> variable-head tests ("slug tests") . Pump tests give a <br /> better approximation as to the response of the overall <br /> aquifer, and not just near the borehole. <br /> I-16 <br />
