<br /> <br />the sampling system and will be discarded prior to actually obtaining a filtered sample. <br />Equipment decontamination with deionized water will be performed between each sample <br />location. <br />Field measurements will include pH, dissolved oxygen, temperature, and specific conductance. <br />Specific conductance, temperature, and dissolved oxygen will be measured in situ using <br />portable specific conductance and dissolved oxygen meters. Field pH will be measured from <br />the composited water sample using a portable pH meter. If there is reason to suspect that <br />water in the stream cross section is not thoroughly mixed, specific conductance measurements <br />will be taken within 10 feet of both the right and left banks, and the results recorded to <br />document such conditions. <br />2.5 SAMPLE ANALYTICAL TESTING PROCEDURES <br />Water quality samples collected under this plan will be tested for a core list of chemical <br />parameters to provide a consistent basis for comparison of data between monitoring locations. <br />More detailed analysis of the pond water quality samples will be conducted on a quarterly <br />basis. Phis will provide additional chemical characterization of water in the pond on a <br />seasonal basis in the event discharge of water is necessary in the future.
