All peaks will be reported. Metals shall be analyzed and reported as totals (except for chromium). The Discharger shall determine at each sampling whether there is a statistically significant increase over water quality protection standards for each parameter and constituent analyzed. Ground Water Quality Protection Standards: New monitoring wells were installed at the Forward waste management facility during the summer of 1987. Once four quarters of sampling data have been obtained for the background wells MW -6, MW -8 and MW -12 background values for the ground water indicator parameters will be calculated. Upon acceptance and/or revision by the Board, these background values will be used as Water Quality Protection Standards. If subsequent sampling of "background" monitoring wells indicates significant water quality changes due to either seasonal fluctuations or other reasons unrelated to waste management activities at the site, the Discharger may request modification of these water quality protection standards.
