TUN 25 '96 11=21AM SMITH ENVIRONMENTAL TECH CORP P.5 <br /> QLD PROCEDITRM <br /> Site Safettt. � <br /> This plan describes the safety requirements for field -work performed at the site. The site <br /> safety plan is applicable to personnel of Smith Environmental Technologies 'Corporation <br /> (Smith Environmental) who perform the field work. A copy of the site safety plan.is available <br /> for reference by appropriate parties during the work. The on-site representative of Smith <br /> Environmental acts as the Site Safety Officer. <br /> Grab b 9kAtAwdRoUr aD Ilinp or IlZssolved Oxygen And Oxldati - Ike ti 1 <br /> •A temporary casing will be set in each boring to allow for the collection of a groundwater <br /> sample- The depth to water in each boring is measured to the nearest 0.01 foot with a Solinst <br /> electric water-level sounder cleaned with a laboratory-grade, non-phosphate detergent and <br /> clean water before use in each boring. A sample of the formation water is them collected from <br /> the surface of the water in each of the borings with a clean disposable bailer. The bailer is <br /> i <br /> lowered slowly and gently into the casing in the boring to prevent mining. The water sample <br /> � is then slowly transferred to laboratory-cleaned glass 100.300 ml sample containers. Enough <br /> water is placed in the jar to allow some overflow of the sample. Immediately, a dissolved <br /> �;xz gen-probe and an oxidation-reduction potential meter are put into the sample container and <br /> the.readings are recorded. <br /> ��ruuun xa�ter SamulingonitoffM Y&J r DI olved Oxygen a xldidgT- detSWM <br /> The static water level in each well is measured to the nearest 0.01 foot with a Solinst electric <br /> water level sounder cleaned with a laboratory-grade, non-phosphate detergent and deionized <br /> water before use in each well. For wells with a history'of contamination, a clean bailer is use <br /> to obtain a sample from the surface of the water in the well for subjective analysis. of <br /> hydrocarbons. The sample is retrieved and visually examined for floating product, sheen, <br /> color, and clarity. <br /> Approximately 3 to 5 well volumes are purged from eacb well with a pre-washed submersible <br /> pump to allow sampling of representative formation water.
