Samples and analyses are summarized in Table 5-1 a. Appropriate containers and <br /> physical and chemical preservation techniques will be applied during field activities to help verify the <br /> acquisition of representative analytical results. Analytical methods, container and preservation <br /> requirements, and maximum holding times are summarized in Table 5-2. <br /> M <br /> Project No.: 185704833.5.3&5.4 5.2 <br />
