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 are as follows. <br />Flow Measurements <br />Flow measurements may be taken by two different methods. A portable Parshall flume <br />manufactured by Baski, with a one- inch throat may be used. An instantaneous reading is taken <br />off the staff gauge, converted to Cubic Feet per Second, then to Gallons per Minute (GPM). <br />The second method involves use of a one gallon or five gallon bucket and stop watch. The <br />amount of time required for the flow to fill the bucket is measured. The result is a flow <br />measurement in 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 be <br />well downstream of where the discharge from the spring or seep reaches the surface. <br />Monitoring <br />A. In -situ measurements. Temperature, pH and specific conductance are taken on site in the <br />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 grab <br />sample taken. Parameter List A -3, as outlined in Table 4.8 -12, will be analyzed for each <br />sample. Samples are also generally taken for springs and seeps with a flow rate greater <br />than 2 GPM for additional 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 24 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 Q, XXXI, Part A for discussion of the monitoring equipment to be used. <br />IV. Sample Schedule <br />Springs and seeps will be sampled on a semi - 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 by <br />March 15 of the following year. <br />GCR 11/12 <br />Permit RevisionsUR- 11MAPP -Q31] <br />
