f� <br /> HORIZON ENVIRONMENTAL, INC. <br /> FIELD METHODS AND PROCEDURES <br /> ; .JI <br /> The following section describes field procedures that will be completed by Horizon <br /> = Environmental Inc. (Horizon) personnel in performance of the tasks involved with this project. <br /> 1.0 HEALTH AND SAFETY PLAN <br /> =`1 <br /> Ed Field work performed by Horizon and its subcontractors at the site will be conducted according <br /> to guidelines established in a Site Health and Safety Plan (SHSP). The SHSP is a document <br /> that describes the hazards that may be encountered in the field and specifies protective <br /> 3 equipment, work procedures, and emergency information. A copy of the SHSP will be at the <br /> site and available for reference by appropriate parties during work at the site. <br /> 2.0 GROUNDWATER DEPTH DETERMINATION <br /> Each monitoring well is opened and allowed to equalize to atmospheric pressure prior to <br /> sounding. Depth-to-water is measured to the nearest 0.01-foot using an electronic, hand-held, <br /> water-level indicator. The measuring point is the survey mark on the top of the well casing. <br /> The tip of the probe is examined in order to determine the presence or absence of product <br /> sheen. <br /> 3.0 MONITORING WELL PURGING & SAMPLING <br /> Prior to purging, a clean, transparent bailer is lowered into the well, and a sample of <br /> groundwater is hoisted to the surface. The sample fluid is inspected for the presence of free- <br /> floating product on its surface. Sampling activities conducted subsequent to the initial well <br /> •,', } <br /> development activity will be preceded by purging a minimum of three well-volumes by hand- <br /> J - <br /> •�1 <br />
