' SUBURBAN SAND AND GRAVEL <br />ROAD RUNNERS REST 11 <br />' CASE #'s 13-BaCP d 20-92-C(A) <br />' imate since the State Engineers records are vague on the exact <br />location of some wells. The numbers in the left column of the <br />' table correspond with the numbers beside each well on the map. <br />Review of the State Engineers records indicate there is 1 <br />well within 200 feet of this site. we own 6 wells on the site <br />that will be affected by this dewatering and three of them will <br />' be removed as mining progresses. From the water Table Contours <br />map contained in this submittal we find that the ground water <br />' flow in this area is from the southeast as it approaches the <br />river and then runs parallel to the river. <br />Review of available documents from other permit applications <br />' suggest a possibility that as the lake is pumped down, the draw <br />down could extend to 900 feet from the lake area. If this is the <br />' case, our dewatering could affect 13 wells around or on the <br />facility. Four of the wells are deep domestic well varying in <br />' depth form 450 feet to 570 feet deep. These wells will not be <br />impacted by surface aquifer dewatering. The remaining 9 wells <br />' are all surface wells and average 39.4 feet deep. Three of these <br />are domestic wells that will most likely be replaced as part of <br />the Rocky Mountain Arsenals mitigation plan. The rest are non <br />' exempt irrigation wells. <br />The wells that could possibly be impacted are those along <br />' the eastern side of the property. While these are up gradient <br />from the excavation area they fall in the drawdown area around <br />' the mine. Since they are up gradient the impacts of mining will <br />be less because the ground water has to flow thru them to get to <br />' the excavated area. One factor that will lessen our impact is <br />the fact that there is a free body lake immediately east of <br />Brighton Road. With the lake being in close proximity to the <br />' wells the ground water table will tend to keep the ground satu- <br />rated to a higher level that if it did not exist. Well # 1 is <br />' the closest to the dewatered area. This well has had numerous <br />problems in the past that have been related to its age. The <br />' owner has attempted to have Albert Frei and Sons, inc. and <br />' 6 <br />
