All borings/Vins-rill be drilled using an 8-inch-diameter <br /> continuous flight hollOW-stem auger: Two wells will have a �" <br /> 4-irrh-diameter PVC.casi s and a third will have a two-inch casing. ^ x Ly <br /> The specific constructiongdetails for each well will be based on e y <br /> results of the drilling and sampling Program. The following well _ ;E <br /> construction standards, in general, will be used: <br /> Soil samples will be obtaijed approximately every 5 feet to the max- <br /> imum depth explored. All samples will be sealed in brass tubes and <br /> the ends covered with aluminum foil and caps taped on aver the <br /> foil. Samples will be placed immediately into an ice chest. The <br /> augers and sampling equipment will be steam cleaned prior to start- ' }' <br /> r-� <br /> ing each boring, the sampling equipment will be washed in a solo- ` <br /> tion of trisodiulm phosphate and-tap water-and rinsed in distilled <br /> water between samples. The soil samples obtained will be accom- <br /> panied <br /> by a chain-of-Custody foam, which will be turned over to a <br /> chemical laboratory for testing. We anticipate that all wells will <br /> be 15 feet deep. The wells will have screened sections with 0.02 <br /> diameter slots from the bottom to approximately two feet above <br /> Engineers 1355 WalowWey Telephone Arizona Colorado Texas N <br /> and Suite 109 415/887-9660 Alaska Hawaii <br /> Geosc,ent,sts Concord,CA 9452pi <br /> California Nevada <br /> = 5�� i1P-t � ` s <br /> &'t' x t• .�. <br /> Y <br />
