h� KLEINFELDER <br /> Z' i <br /> i. <br /> t o SiocRing well covers,`will be installed at the surface to protect <br /> the wells and allow traffic movement. The covers will be set <br /> slightly : above grade and a tapered concrete apron will be <br /> constructed around each well cover to prevent surface runoff <br /> from entering the well. <br /> rs <br /> o A stainless steel well identification tag displaying pertinent <br /> well information will be attached to the well head. <br /> el and ling Procedures <br /> Well Dev Samp <br /> Monitor' t <br /> 3.2.1 �1 <br /> The monitoring wells will be developed after installation. Each well will <br /> first be sampled <br /> acrylic bailer to visually inspect the <br /> � with a clear <br /> sample for a product layer or sheen. If no product layer or sheen is <br /> observed on thewater samples, the wells will be developed with a surge <br /> block,/air lift develaPment tool. Surging with the tool along the screened <br /> interval of .the well will be perform to draw the sediment frcnn the <br /> formation into and out of the well, and to set the sand pack. The <br /> sediment laden water . will be air lifted or bailed fran the well. Each <br /> E well will be developed until the discharge water runs relatively clear of <br /> 5 to 10 well volumes are anticipated fines, Approximately £or removal <br /> from each monitoring well. water diarged water wi1Z be placed _in clean, <br /> F pepnent of Tzanspoxtaton approved, 55 gallon hazardous waste drums. <br /> .. - <br /> WatAX from each well will be placed in separate drums, labeled with well <br /> j identification, and dated. After the wells have been developed, the <br /> formation will be allowed to stabilize for approximately one week before <br /> l <br /> sampling. Disposition of the development water will be by EEKID. <br /> The sampling procedure will be initiated by measuring the depth to the <br /> static water level. All well caps will be removed and the piezometric <br /> presence allowed to equilibrate with atmospheric pressure prior to <br /> measuring the depth water. The well will then be purged and sampled with <br /> 29-88-03 13 <br /> } <br /> f <br />
