Vacuum on the [ailing lysimeters was verified on June 28`", no water was present for sampling
and subsequent analysis.
Depths to water were collected for the tailing impoundment main embankment piezometers and
the West Pit monitoring wells on June 27's. June tailing impoundment piezometer measurements
identified these installations were either dry or contained less than 12 inches of water as
illustrated in Table 2. Tables 1 and 2 below identify the depth to water measurements collected
for each of the site monitoring wells, piezometers and lysimeters as required by the terms and
conditions of the TR-32 QA/QC plan.
The tailing impoundment collection pond underdrain flow was pumped intermittently during the
month to minimize the collection pond level. The Teak detection system was measured on June
28`s. The June tailings pond underdrain flow average was 44.15 gpm and a total of 850 gallons of
water was excavated from the leak detection system yielding a monthly average of 31.48 gpad.
During June the West Pit water treatment plant operated efficiently discharging a total of
8,212,400 gallons (25.20 acre-feet) of water to Rito Seco Creek and a total of 1,072,900 gallons
