Mr. Richard Mills - 3 - March 27, 1986 <br />3) A table compiling specific information on monitoring sites (site <br />location description, monitoring objectives, completion data or permit <br />references to completion data on wells) would facilitate interpretation <br />of the data. <br />4) A tabulation of all monitoring data collected. We are interested <br />in observing trends over time and in comparing current data with <br />baseline. It would be helpful if the specific water quality data could <br />be compiled with previous data as the field parameters were presented <br />in the 1985 AHR. Additionally we would be interested in some massaging <br />of the data, as presented in the Empire AHR: annual compilations of the <br />average, standard deviation and range for each parameter at each site. <br />Cumulative averages of multiple years' data is inappropriate, however, <br />as the Division is interested in trends. <br />5) The calculation and reporting of mass balance on each sample which <br />has major cations and anions analyzed would improve our evaluation of <br />your quality control, as mentioned earlier. <br />6) Please utilize the "Remarks" column on the field parameters <br />tabulations to comment on pertinent weather and hydrologic conditions <br />so we can distinguish between storm events and ambient high flow <br />conditions. <br />7) Graphical analyses of the data will expedite the interpretation of <br />the hydrology. We would like to see: <br />a) flydrographs of streamflow and ground water well depth data; <br />b) Cumulative graphs (baseline to present) of total iron, TDS and <br />TSS at all surface water sites as well as cumulative graphing of <br />all parameters which are at levels 75 percent of receiving stream <br />standards or applicable irrigation standards; and, <br />e) Piezometric-style mapping is of salt plume concentrations in <br />aquifers. <br />We hope that the recommendations presented herein will improve the quality of <br />CYCC's monitoring program and future AHR's. If you have any questions, do not <br />hesitate to call. <br />Sincerely, <br />Catherine W. Begej <br />Reclamation Specialist <br />CWB/pjh <br />cc: Dan Mathews <br />8682E <br />
