The majority of the bugs have been worked <br />out of the system, but there are still a few that need to be taken <br />care of during the coming months. One that I'm sure you will <br />observe is that the summary tables for the water year data does not. <br />have "Water Year" in the title of the table.

Due to the intensive monitoring program <br />for this area it was decided it would be best to have the data end <br />text presented in its own appendix. Until the .monitoring program <br />is reduced I imagine it will be best to continue handling this part <br />of the report in this manner. Please let me know if you-have any <br />thoughts on this. <br />As you are reviewing the data you will note that selected stations <br />have more than the required sample episodes. :This is pertinent for <br />stations 39, 84, 109 and 115. This sample count numbers reflect <br />the additional sampling that was conducted at the stations, for <br />example when the Division sampled 301 TCC obtained a split sample. <br />This is reflected in the larger sample; number. This is just <br />brought to your attention so that you cari ;better understand the <br />difference between sample numbers. <br />The report indicates that the Trout Creek sandstone replacement <br />well will be completed in June, 1994. "' This. well has been an <br />ongoing concern due to the difficultly encountered .in providing a <br />good seal on top of the sandstone. The first seal ,that was placed <br />installed did not set up quickly .enough and water piped up through <br />
