Dear Mrs. Funk: Enclosed are the results of sampling and analyses of groundwater from Monitoring Well Nos. 1, 2, 3, and 4 at McKenney's Air Conditioning. As can be seen, analYses of the groundwater samples show gasoline contaminants in three of the monitoring wells. Table 1 shows the static water levels measured in the five monitoring wells since October 1990. Four monitoring wells were sampled on June 14, 2002. Approximately six gallons of water were purged from two of the monitoring wells prior to sampling. Monitoring Well Nos. 3 and 4 were not purged due.to the low water levels in the wells. Monitoring Well No. 5 was not sampled since it was dry. The water was tested, with a Haydac water testing meter until pH, temperature, and conductivity stabilized. The purge logs are included in Attachment A. The groundwater samples were collected using polyethylene disposable bailers. The water samples were placed in VOC vials furnished by BC Laboratories. The vials were then placed on blue ice and delivered to BC Laboratories for analyses. The samples were analyzed for total petrOleum hydrocarbons as gasoline and BTX&E constituents using Modified 'EPA Method 8015 and EPA Method 5030/8020, respectively. TheY also were analyzed for methyl-t-butylether (MTBE). The analytical results are included in Attachment B. Tables 2A through 2E show the results for this sampling event and all past events. As can be seen, the BTX&E constituents in th'e groundwater sample from Monitoring Well No. 1 have decreased since September 2001.

The constituents in the groundwater sample from Monitoring Well No. 3 have generally stayed the same since September 2001. The total petroleum hydrocarbon concentrations for the September 2001 and June 2002 sampling events was 12,000 txg/l' and 11,000 ~g/1, respectively. The benzene concentration increased from 2.2 /~g/l to 4.6 /xg/1. The contaminant concentrations in the groundwater sample from Monitoring Well No. 4 decreased since September 2001. The total petroleum hydrocarbon concentration decreased from 23,000 ~g/1 to 240/~g/1 and the benzene concentration decreased from 20 ~g/1 to 2.4 ~g/1. It should be noted that the groundwater level has fallen an average of about 6.5 feet in the area of Monitoring Well Nos. 1, 2, and 3 since September 2001.
