(1.)Samples taken on 12-19-95 were analyzed outside of their holding time. An additional compound, 1,2-Dichloropropane was detected in Montgomery Ward well MW-1 (5.3 ppb)sampled on 12-06-94. An additional compound, 1,2-Dichloropropane was detected in Montgomery Ward well MW-1 (13 ppb)sampled on 02-08-95. An additional compound, 1;2-Dichloropropane was detected in Montgomery Ward wells MW-1 (1.6 ppb)and MW-4(1.3 ppb) sampled on 06-21-95. Methylene chloride was also detected in veils MW-3 (4.8 ppb)and MW-4(2.4 ppb),respectively. Methylene chloride is interpreted to be the result of laboratory contamination. An additional compound, chloroform was detected in Montgomery Ward wells MW-1„(3.7 ppb),MW-5 (3.0 ppb),and MW-6 (1.3 ppb)sampled on 03-11-96. An.additional compound, 1,2-Dichloropropane(1.2 ppb)was detected in Montgomery Ward well MW-1 sampled on 06-19-96. An additional compound, chloroform was detected in Montgomery Ward well MW-1 (2.6 ppb)on 12-05-96. An additional compound, chloroform was detected in Montgomery Ward wells MW-1 (1.6 ppb)and MW-5 (12 ppb)on 12-10-97. An additional compound, 1,2-Dichloropropane was detected in Montgomery Ward wells MW-1 (1.2 ppb)and VEW-5 (3.4 ppb)sampled on 09-16-98. An addrtronal compound, P-Iso ropyltoiuene was detected in Montgomery Ward wells MW-1 (1.5 ppb), VEW-4(8.4 ppb) and VEW-5(6.2 ppb)sampled on 09-16-98. An additional compound, SEC-Butylbenzene was detected in Montgomery Ward wells VEW-4(17.0 ppb)and VEW-5 (11.1 ppb)sampled on 09-16-98. An additional compound, SEC-Butylbenzene was detected in Montgomery Ward well VEW-4(15.0 ppb)sampled on 12-22-98. An additional compound, SEC-Butylbenzene was detected in Montgomery Ward well VEW-4 (2.8 ppb)sampled on 06-18-98. An additional compound, P-Isopropyltoluene was detected in Montgomery Ward well MW-2(1.1 ppb)sampled on 09-16-99. 09/19/00 Well MW-18 also contained tetrachlorotehene at 1..4 pg/L;Well MW-19D also contained sec-butylbenzene(3.1 µg/L)and p-isopropyltoluene(1.1 µg/L); Several wells contianed methylene chloride,a laboratory contaminant. 12/13/00 Well MW-13 (25.0 µg/L)also contianed methylene chloride a laboratory contaminant. Several wells contained chloroforms in low concentrations. The chloroform is believed to be derived from the tap water used to decontaminate the pump and hose system. < =Not detected at or above concentration limit listed. 1232:ANALYTICAL-DATA ENVIRONME.NTAC AUDIT,INC".o
