• PART B <br />SPRING AND SEEPS <br />SAMPLING PROCEDURES <br />The sampling procedures for springs and seeps are generally the same as the surface water procedures <br />presented in Part A. The monitoring equipment used and procedures to be followed are the same as <br />Section III of Part A. The specifics of the spring and seep sampling follows. <br />Flow Measurements <br />Flow measurements may be taken by two different methods. A portable parshall flume with a <br />two- inch throat may be used. An instantaneous reading is taken off the staff gauge, converted to <br />Cubic Feet Per Second, then to Gallons Per Minute (GPM). <br />The second method involves use of a gallon bucket and stop watch. The amount of time <br />required for the flow to fill the gallon bucket is measured. The result is a flow measurement in <br />GPM. <br />Flow measurements are taken at a sample point where all the flow can be measured. On occa- <br />sion, this may require diverting the flow into a channel. Therefore the flow measurement could <br />be well downstream of where the discharge from the spring or seep reaches the surface. <br />II. Montoring <br />A. In-situ measurements. Temperature, pH and specific conductance are taken on site in <br />the flowing water section of the discharge. <br />• B. Grab Samples. All springs and seeps with a flow rate of 5 GPM or greater will have a <br />grab sample taken. Parameter List A-3 as outlined by Table 4.8-12a will be analyzed for <br />each sample. Samples are also generally taken for springs and seeps with a flow rate <br />greater than 2 GPM for additonal definition of springs and seeps. <br />Samples are refrigerated until shipment to the lab. During shipment, samples are 'iced' <br />and shipped in coolers. To meet recommended EPA holding times, samples must be <br />received by the lab within 48 hours of the time the samples were taken. <br />Guidelines as outlined by the lab are followed as to the number of bottles to be filled, <br />samples to be preserved, storage, etc. Chain of Custody forms provided by the lab are <br />filled out and lab handling instructions are followed. <br />III. Monitoring Equipment <br />See Appendix t1, XXIV, Part A for discussion of the monitoring equipment to be used. <br />IV. Sample Schedule <br />Springs and seeps will be sampled on asemi-annual basis. Initial sampling will normally occur in <br />May/June with parameter list A-3 evaluated. In September, springs and seeps will again be <br />monitored. However, only flow, pH, specific conductance, TDS, and temperature will be obtained <br />during the fall sampling. The data will be reported to the Division in the Annual Report provided <br />by March 15 of the following year. <br />wm w~ <br />rDM4lTR79NPP~36~ <br />T2-76 <br />~/lY~9~ <br />
