<br />For streams deep enough for reasonable depth integration (i.e., >0.5 ft deep), samples will be <br />collected using the depth integrated-equal width increment method at a minimum of 4 points <br />across the channel. For streams which are wadable, samples will be collected using a 1 gallon <br />(analytical quality) plastic bottle. The bottle will be hand-held and used the same as for USGS <br />depth integrating sampling equipment (i.e., these will be depth integrated, equal width <br />increment samples). Samples will be collected during the high-flow (non-wadable) periods by <br />composited two grab subsampies collected from the right and left banks. The general <br />sampling and measurement methods for each station is listed in Table 2, Data Collection <br />Methods. <br />Table 2 <br />Data Collection Methods <br /> <br /> <br />::Station Identification:;:.;.:: <br /> <br />;. .:.:.::Collection Method ..:..:.: ,... <br />,. . <br />: ..:.:: MeasureemenY. :::::::::. <br />P-1 Grab Weir Water Level <br />POND-1 Lined Pond Grab Pond Staff Water Level <br />UN-1 RC-1 and RC-2 DI-EWI• Direct Current Meter <br />"Depth integrated equal width increment if wadable. <br />Sufficient sample volume will be collected one time for the entire analysis. Water will not be <br />collected over any period greater than approximately 5 minutes for any given sample. Water <br />samples will be collected using appropriately-sized collection containers made of material inert <br />to the chemical analyzes. One-gallon plastic collection containers may be used for the <br />collection of samples tested for metals or inorganics. Glass or teflon collection containers may <br />be required for samples tested for organic compounds. Discharge measurement methodology <br />are detailed in Appendix B, Streamflow Measurements. <br />2.4.4 Sample Processing <br />Both filtered and unfiltered samples will be processed from the composited sample. The <br />wmposite container will be thoroughly agitate the composite container while pouring <br />unfiltered water into the sample bottles for inorganic and metal analysis. Samples will be <br />filtered at the time of collection through a 0.45 micron membrane filter using a peristaltic <br />pump and in-line filter. The initial 100 to 2110 milliliters (ml) of filtrate will be used to rinse <br />15 <br />
