SOP No. 5.0 Monitoring Well Install <br />STANDARD OPERATING PROCEDURE No. 5.0 <br />MONITORING WELL INSTALLATION <br />1.0 PURPOSE AND SCOPE <br />The purpose of this document is to define the Standard Operating Procedure (SOP) for installing <br />groundwater monitoring wells in unconsolidated geologic materials and bedrock at the <br />Powertech, Inc. (hereafter referred to as Powertech) Mine Site and in surrounding areas. This <br />SOP describes designs, procedures, and materials used to construct monitoring wells that will <br />produce accurate groundwater level measurements and representative groundwater samples. Well <br />construction and abandonment reports will be submitted to the Colorado State Engineer. The <br />step-by-step procedures described herein are intended to be sufficiently detailed to allow field <br />personnel to properly install monitoring wells. <br />2.0 RESPONSIBILITIES AND QUALIFICATIONS <br />The Project manager has the overall responsibility for implementing this SOP. He/she will be <br />responsible for assigning appropriate environmental staff to implement this SOP and for ensuring <br />that the procedures are followed accurately by all personnel. <br />All personnel performing these procedures are required to have the appropriate health and safety <br />training. In addition, all personnel are required to have a complete understanding of the <br />procedures described within this SOP and receive specific training regarding these procedures, if <br />necessary. <br />All project staff are responsible for reporting deviations from this SOP to the Project Manager. <br />3.0 RELATED STANDARD OPERATING PROCEDURES <br />The procedure for monitoring well installation set forth in this SOP is intended for use with the <br />following SOPS: <br />SOP 3.0 Borehole Logging <br />SOP 6.0 Water Elevation Measurements <br />SOP 10.0 Decontamination of Sampling Equipment <br />SOP 11.0 Sample Management <br />SOP 15.0 Well Development <br />SOP 22.0 Groundwater Sampling <br />SOP 35.0 Surveying (Land and GPS) <br />7/28/08 Page 1 of 10 R Squared Inc.
