Total Metals (unfiltered) <br /> b. Dissolved Metals (filtered) <br /> c. Cyanide <br /> d. TSS <br /> e. Nitrate/ Nitrites <br /> 18. To collect filtered samples; <br /> a. Attach 45 micron filter to peristaltic pump tubing. <br /> b. Allow sample to saturate and to flow through filter (approximately 200 <br /> mL). <br /> c. Discharge and discard approximately 100 mL of H2O from filter <br /> d. Collect filtered sample in appropriate sample bottle(s). <br /> 19. Place samples in cooler on ice. <br /> 20. Turn off pump at pump controller box, remove power cord from pump. <br /> 21 . Pull pump and tubing from well, reeling pump cord back onto pump reel. <br /> 22. Decontaminate equipment (submersible pump, peristaltic pump) <br /> • 23. Clean up sampling site and move to next location. <br /> Monitoring Well Sampling, Dedicated Electric Pumps <br /> The compliance well at the External Storage Pond (ESPMW) has a 240 volt dedicated <br /> pump. Grounding on all electrical driven pumps must be certified by CC&V's electrical <br /> department once per year. It is of utmost importance that the sampler inspects all <br /> electrical leads and connection prior to use. The Honda generator has adequate <br /> power to run this pump. After the generator has warmed up, plug the twist lock <br /> power lead into the generators 30 amp receptacle, and switch the voltage control to <br /> 240 volts. There is a short time delay before water is pumped up, and out the <br /> discharge hose. If the well is purged dry the flow controller will shut the pump off <br /> automatically. <br /> There are two wells in Grassy Valley,four Wells in Maize Gulch, and four wells in lower <br /> Arequa Gulch that are also dedicated electric pumps that require a generator, and <br /> either the BCD, or converter controller. Be familiar with the safety features with the <br /> generator, and have the electrical department approve all grounding requirements <br /> prior to use. <br /> • 1. Upon arrival at well location perform field level risk assessment to determine <br /> location is safe to perform surface water sampling.
