WORWEST <br /> COR PORAT ION <br /> A pressure transducer was installed at each monitoring location to capture continuous <br /> stream depth and will be programed to collect data every 15 minutes. Instantaneous flow <br /> will be measured during each of the monthly site visits. A rating curve will be developed <br /> using the continuous stream depth and instantaneous flow measurements. The rating <br /> curve will be used to estimate flow for each of the continuous stream depth <br /> measurements resulting in a flow hydrograph illustrating flow over time. <br /> Handheld water quality meters will be used to collect the field parameters of pH, <br /> temperature, conductivity, dissolved oxygen (DO), and turbidity of the water at the <br /> compliance monitoring sites. Field parameters and water quality samples will be <br /> collected during each of the monthly site visits. Documentation during each site visit will <br /> include the following, recorded in both the field book and on the sample sheets: <br /> • Date and time of arrival at location <br /> • Sampler initials <br /> • Weather conditions <br /> • GPS coordinates (NAD83) and elevation <br /> • Photo number and direction <br /> • Daily instrument calibration information <br /> • Sample collection time <br /> • Sample bottle suite collected <br /> • Field parameters (pH, temperature, conductivity, DO, turbidity) <br /> • Description of sample (color, sediment, etc.) <br /> • Flow measurement information <br /> Other pertinent information will be recorded as needed to assist with characterizing the <br /> sampling event. <br /> 2.3.1 Surface Water Sample Collection <br /> Water quality samples of Little Turkey Creek will be collected monthly. Prior to arrival <br /> at the first sample location each day, the handheld water quality meters will be calibrated <br /> (USGS, 2015). All necessary equipment and supplies will be gathered and taken to the <br /> monitoring location. The handheld field parameter meters will be placed into the stream <br /> and allowed to stabilization prior to recording the readings. The sample bottle set will be <br /> labeled with the sample ID, date, and time of collection, and sampler initials. The surface <br /> water sampling analyte list is summarized in Table 2.1. All sample bottles will be filled, <br /> using one of the non-preserved bottles to fill the bottles containing preservative.
