Tables 1 and 2 below identify the depth to water measurements collected for <br />each of the site monitoring wells, piezometers and lysimeters as required by the terms <br />and conditions of the TR-32 QA/QC plan. <br />The tailing impoundment collection pond underdrain flow was pumped intermittently <br />during the month to minimize the collection pond level. The leak detection system was <br />measured on March 29`h. The Mazch tailings pond underdrain flow average was 51.32 <br />gpm and a total of 520 gallons of water was excavated from the leak detection system <br />yielding a monthly average of 17.33 gpad. <br />P.O.
