Water level drops of a few feet have been attributed to this drought. <br />This may be refl~ec~ed in the recent drop in the level of the pond north of Mr. Andrewe• place <br />and may also paktiially explain the static water level drop in his wells. <br />Findings <br />1. Mr. Andrewe has experienced a water level drop in the last year in two wells located about <br />900 feet eouth~,est of the Bucklen pit. Mr. Andrews believes the water level has dropped <br />about 8 feet. ~qe~current level was measured at about 17 feet bql. The current water level <br />in the dewateringf pit ie about 25 feet bgl. <br />2. A drop of 4 t0 5 feet has occurred during the past year in a pit located about 500 feet <br />north of the Andrews wells. <br />3. There is apparently no mitigation agreement between the Bucklen Equipment Co. and Mr. <br />Andrewe for damage to his we1Le. <br />4. The Andrewe wells are more than 600 feet from the Bucklen Pit which is the distance <br />generally u~edipl Identifying wells which can potentially be impacted. <br />5. The water level measuremeni:s completed during the inspection verified that the alluvial <br />aquifer has not.been depleted in Mr. Andrews' deep well. The fact that the deeper well <br />experiences prod~uc#ion drop meiy be a function of the well itself. At this point, there is <br />not enough info at,ion and Mr. Andrews will need to provide completion data to the Division <br />before the sour~6 of this problem can be determined. Necessary information includes the <br />drillers reportii~and lithologic logs, well completion reports, the depth at which the <br />submersible pump~,is set, and how and when the well was developed. <br />6. There is inauPficient data at this time to determine the cause for the water level drop <br />in Mr. Andrewe' water wells. The cause might be attributed to a regional drought, dewatering <br />activities in theg[avel operation, a combination of the two, or to an unrelated phenomenon. <br />The operator neeileto submit to the Division a plan for verifying if dewatering activities <br />have impacted Mr. Andrews' wells or some documentation demonstrating that the operation has <br />not impacted the wells. This should be received by the Division no later than 7/8/94. <br />Due to the lack ol` site specific monitoring information, the operator should determine if any <br />local monitoringl'Idata exists which might establish a relationship between Mr. Andrew' wells, <br />the dewatering activities and to the effects of the local drought on wells in the vicinity. <br />Information can b@ obtained from the following agencies: The Central Colorado Water <br />Conservancy DietiS.ctt, Northern Colorado Water Conservancy District, Lakewood Branch of the <br />USGS, Water Resou7dcee Division and the Northern Front Range Water Quality Planning <br />Association. The'resulte should be included with the dewatering impact report due on 7/8/94. <br />Z & E Contact Address <br />NAME Richard Bucklen <br />---~•- <br />OPEAATOR Bucklen~E4u ipment Company, Inc. <br />STREET 804 No~th 25th Avenue <br />CITY/STATEJZIP Glteelev, Colorado 80631 <br />cc: Carl Mount,DMG <br />Elmer Andrews <br />Shawn Hoff - OSE <br />~ CE <br />~ BL <br />~ FS <br />^ ~`' <br />~ HMWMD (CH) <br />SE <br />WQCD (CH) <br />~ OTHER <br />
