The report contains tables, figures and appendices presenting the results of <br />the hydrologic monitoring for 1995. It also contains a discussion of the results. Also <br />the data listing was included with the 1994 AHR response package submitted under <br />separate cover. No significant unpredicted impacts have been observed to date. <br />During the early to mid 1980's a few water quality measurements were recorded which <br />were significantly higher than normal. Most of these were total metal values measured <br />in wells. One was a suspended solids value measured in a well. These values <br />produce inappropriate means and standard deviations making comparisons difficult. <br />Because most of the data used today is dissolved and total recover<;•ble and the very <br />high likelihood that these values were not representative, they have been removed <br />from the database. Table A lists all these values. <br />If you have any questions, please contact me. <br />Sincerely, <br />~~~ <br />Richard A. Mills <br />
