Draft Notes from Charles G. Patterson, Ph.D., Feb. 2007: <br />Water currently flows from the Chandler airshaft, which anecdotally is connected hydraulically <br />with the underground workings and with the backfilled Wolf Park shaft adjacent to the mill. <br />(Figure Ig, Hearne and Litke map compared to Banta and Chaffin). Water that issues from the <br />Chandler airshaft should be sampled by the CDPHE or by an independent contractor as soon as <br />possible. It may represent deep waters underneath the site and may give evidence of a deep path <br />of contamination (Figure 3c and 3d, graphs of U in Chandler airshaft vs Wolf Park). In <br />addition, the spring by Hwy 115 and Rockvale Road (See figure of geography and surface <br />features) should be sampled as it may represent the Chandler airshaft waters as well, and <br />visually appears to be contaminated as it is precipitating large amounts of iron oxide. <br />Compare the boundaries of the coal mines as shown in Chafm and Banta with those of Hearne <br />and Litke (Figure Ig). Hearne and Litke show the Chandler connected to the Wolf Park, Chaffin <br />and Banta show them unconnected. Anecdotal reports from residents state that miners could <br />walk from the Wolf Park to the Chandler, and possibly from the Wolf Park to the Rockvale #3. <br />There is still some cause, in my opinion, to continue to suspect the "Deep Path" through the Wolf <br />Park mine to locations near well #006 in Lincoln Park. Although disputed by the USGS, water <br />levels in the Rockvale, the Wolf Park, and the Chandler agree with local ground water gradients, <br />implying some connection. Early maps show the Chandler and the Wolf Park connected, and the <br />Chandler air shaft, when last sampled, had the same levels of U as did the Wolf Park. <br />
