All peaks shall be reported. 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. The ground water surface elevation ( in feet and hundredths, M.S.L. ) in all wells shall be measured on a quarterly basis and used to determine the velocity and direction(s ) of ground water flow. This information shall be displayed on a water table contour map and/or ground water flow net for the site.
