Detection limits are typically 0.5 ppb, <br /> but range from 0.5 to 500 ppb,historically. Variations in the concentration of VC in well M-06B are due to variations in the detection limit,only. There have <br /> been no reports of VC in well M-06B above detection. See Appendix B for specific values. <br /> Well M-06A <br /> Well ID:M-06A <br /> Aquifer:UpperA/B 100,000 60 <br /> Top Elevation:68.22 <br /> Bottom Elevation:-46.78 <br /> Screen Depth:90-110 <br /> Total Depth: 115 10,000 50 <br /> Diameter:4" <br /> Sampling Schad:SA a y <br /> elevations in feet mean sea level J 1,000 40 a1)i <br /> depths in feet below ground surface (n <br /> 1 c <br /> c A ° ° E <br /> 100 ° pOO ° oO e o ° A. ° o o ° ° °A° °p°°°00 30 > <br /> 0 o A o ° �� O <br /> c A ° ° ° o o°o tva <br /> v10 ° ° 0 0 ° ° 0 0 20 <br /> 0 ° o y <br /> O y <br /> U O O O o LL <br /> O e o 0 0 0 0 00 0 10 <br /> om moo O O w 0 0 0 0 0 0 0 0 00000 <br /> 0 0 <br /> Jan-87 Jan-89 Jan-91 Jan-93 Jan-95 Jan-97 Jan-99 Jan-01 Jan-03 Jan-05 Jan-07 Jan-09 Jan-11 Jan-13 <br /> L TCE o CIS 0 VC --*--Water Elevation <br />
