The <br />alluvial terraces have been modified by consduction of Colorado State Highway 133. The alluvial <br />terrace east of Sanborn Creek contains the infiltration field for the water supply for the mine and the <br />Town of Somerset. As a domestic water supply, the water is sampled monthly. The samples are sent <br />to the Colorado Department of Public Health and Environment for analysis. The samples must meet <br />drinking water quality standards. <br />Furthermore, any significant negative impact to the alluvium of the North Fork of the Gunnison River <br />would also be detected in the monitoring of NF-2, downstream of the azea that could be impacted by <br />any seepage from the Somerset Mine. Even if another monitoring well was installed in the alluvium of <br />the North Fork of the Gunnison River, the information gathered would not change the condition of the <br />abandoned workings in the Somerset Mme that have erristed for over 75 years. <br />22 <br /> <br />
