6.1. Monitoring reports are to be submitted each month to DWQC showing the volume of <br />water treated and the collected analytical data. <br />When water samples are collected, field parameters (location, time, pH, temperature, <br />conductivity, oxygen levels, etc.) will be recorded on a monitoring form. Field filtering <br />and addition of preservatives will be performed in accordance with laboratory <br />instructions. The water samples will be placed into a cooler and packed with ice for <br />shipment to the laboratory. A completed chain-of-custody form will accompany each <br />shipment. <br />Additional sampling will also be needed to properly calibrate the treatment system and <br />trouble shoot if problems develop. More frequent water quality monitoring will probably <br />be needed at startup and during the transition phase from exploration to mining. Samples <br />of untreated water, partially treated water, and treated water may be needed to determine <br />the correct dosing levels and to make adjustments in treatment. Field measurements (e.g., <br />pH, conductivity) and colorimetric analysis for selected constituents (e.g., iron, arsenic) <br />may be helpful in adjusting the treatment system in the field. Once the untreated water <br />reaches asteady-state situation, dosing levels are expected to become more standardized <br />and water quality monitoring for operating purposes may be needed less frequently. <br />The plant operators will be responsible for ensuring that reagent tanks are full and <br />operating properly. The reactor tanks will be inspected and cleaned as needed. The <br />inspections will include recording flow rates, chemicals added, dosing rates, and <br />remaining chemical inventory. The generator, when in use, will be kept fueled and <br />serviced. The treatment trailer will be kept clean and any spillage of chemicals or <br />solution will be cleaned up and containerized immediately. <br />21 <br />
