If the lot must be split into groups for aeration, <br /> then at least one sample shall be collected from each group and tested for <br /> TPH and BTX. <br /> Data from contaminated soil monitoring shall be organized in a tabular form <br /> and submitted to the Board on a quarterly basis. <br /> STATISTICAL PROCEDURES FOR DETERMINING SIGNIFICANT INCREASES <br /> The significance of increases in indicator parameters and waste constituents <br /> over water quality protection standards shall be established using the <br /> statistical procedure described in the ground water monitoring plan requested in <br /> Order No. Provision C. 13. <br />
