This SOP describes designs, procedures, and materials used to <br />construct monitoring wells that will produce accurate groundwater level measurements and <br />representative groundwater samples. Well construction and abandonment reports will be <br />submitted to the Colorado State Engineer. The step -by -step procedures described herein are <br />intended to be sufficiently detailed to allow field personnel to properly install monitoring wells. <br />2.0 RESPONSIBILITIES AND QUALIFICATIONS <br />The Project manager has the overall responsibility for implementing this SOP. HIe /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.
