When volatile <br /> or semivolatile organic compounds are included for analysis,HETI sampling crew members will <br /> adhere to the following precautions in the field: <br /> 1. A new pair of clean,disposable,latex(or comparable material)gloves are to be worn for <br /> each well to be sampled. <br /> 2. When possible,samples will first be collected.from wells known or suspected to contain the <br /> fewest contaminants,followed by wells in increasing order of degree of contamination. <br /> 3. All sample bottles and equipment are to be kept away from fuels and solvents. When <br /> possible,gasoline(used in generators and water pumps)is to be shipped to the project site in <br /> separate compartments of the same vehicle or in a separate vehicle as that in which <br /> sample bottles are shipped. <br /> I <br />} <br /> 7 <br />
