Please respond to each <br />item as appropriate. Provide lab result sheets where sampling data <br />is required. Due to the amount of data missing, the Division did <br />not conduct a detailed water quality review. This will be done at <br />a later time. <br />General Comments <br />The following discrepancies were noted: <br />1. Figure 36 is labeled conductivity but site 8 and site 14 <br />values as representing total recoverable? <br />2. Figure 37 graphs manganese but the y axis is labelled <br />umhos/cm. . <br />3. Figure 38 umhos/cv? <br />4. Figure 42 y-axis is labeled incorrectly. <br />5. Figure 48 title is incorrect. <br />6. Figure 53 label on y-axis and title conflict. <br />7. Figure 20 displays wells 001-SP-1, 2, and 3. Where are these <br />wells in the monitoring plan? <br />8. Why are 1991 values not represented on Figure 34? <br />9. Tables 2 and 3 were not included in the report. <br />
