Ms. Jamie Gaboriau <br />Apri117, 2002 <br />Page 3 aj3 <br /> <br />approximately 1500 feet from the northern property boundary of the pit. All of these welts have <br />been completed in the alluvium and ate considered "shallow" wells. <br />Since June of 2001, Aggregate has been collecting monthly water levels at. three monitor wells .. <br />adjacent to the site. In review of this information, the data indicates a gradual decline in water . <br />levels, with a maximum total decline of 11.5. feet at Weli #1 from original conditions in 2001 <br />through April 5, 2002. Specifics regarding monitor well. construction and installation with <br />regard to pumping from the site are notknown at.this time: <br />OTHER OBSERVATIONS . ~ ' <br />A general site review +,vas conducted on April lo; 2001. Prior to this site review, .general <br />information regarding land ownership in the azea was determined based on Weld County. <br />Assessor's Map #1471 for Sections 29, 30, 31, and 32, all Township 1 North; Range 66 West: In <br />Section 30,'two pazcels owned by Mr. Braneucci were identified in the N %z of the NE'/<,.and in <br />the NE Y< of the SE '/< of the section. Several wells were observed just west of WCR 27, none of <br />these wells were observed to be pumping. However; a well located just north of WCR 4'and <br />west of WCR 27 was observed to be pumping. The ownership of the parcel on which the well is. ,. <br />located was not identified.. Water from the well was being discharged into an open earthem ditch <br />that ran along the northern boundary of two other separate pazce]s identified as.Elms and. Case. <br />Flow or other related measurements were not taken at the well. <br />A ditch lateral was noted carrying water along WCR 27 delivering water to the north. Orie of. . <br />Mr. Brancucci's wells is located just west of £nis ditch neaz the intersection of WCR 6 and 27. . <br />Additionally, two other ditches were observed east of WCR 27 one of which is believed to be the <br />main Fulton Ditch. Both of these ditches were canrying water at the time. <br />The ski lake located immediately east of HWY 85 and east of the pit was also observed. Water, `. <br />was observed in the lake; however; the level appeared to be somewhat less than the' high water <br />mark on the banks. No measurements were taken at the ski lake. Also, several area ponds were <br />observed east of WCR 27 along WCR 4. The water level in all of these ponds appeared Lo be <br />less than the high water mark. <br />SL7r[~IARY <br />An in-depth ground water analysis has not been completed for this area to determine the <br />potentia3 affects of dewatering at the Platte Valley Pit. However, based on the available <br />information, a preliminary assessment has been determined as follows: <br />• `Data available from the three Aggregate monitor wells indicates that the ground water <br />table has declined by as much as 11.5 feet. Since these wells are located immediately <br />adjacent to the pit, it is anticipated that. this draw down is probably a direct result of the <br />dewaiering operations. <br />• The draw down in the water table may extend out from the pit. However, the draw <br />down at a location approximately 0.25 miles from the pit is anticipated to be <br />considerably less -than the 11.5 draw down noted at the pit based on information <br />
