Please respond to each item as appropriate. <br />General Comments <br />Overall, a great improvement was noted with regard to meeting the required frequency of <br />visits and taking the required sample. Site visits were generally conducted in accordance <br />with the approved plan with very few misses noted. <br />The following discrepancies were noted: <br />~~- 1. In the 1994 AHR, the discussion under the water quality heading for bedrock wells <br />is missing. <br />~~ 2. In the 1995 AHR text, the statement is made "..only one significant spoil spring was <br />observed in 1995...? Is this statement accurate? <br />3. The 1994 report indicates via Figure 7 that well 026-94-M001 had a October TDS of <br />approximately 800 mg/I. The 1995 report via Figure 7 indicates that the October <br />1994 TDS was 500 mg/I for this well. Which is correct and why do the two reports <br />r ' show different results on the Figures for the same date? <br />~~rV 4. The 1994 report indicates via Figure 7 that well 026-94-M002 had a October TDS of <br />approximately 1200 mg/l. The 1995 report via Figure 7 indicates that the October <br />1994 TDS was 750 mg/I for this well. Which is correct and why do the two reports <br />show different results on the Figures for the same date? <br />5. For sites reporting water level, no data sheets were provided (302, 304, 307).
