The next decisive tests <br />to indicate poor quality mine drainages were the determination <br />of the concentrations of SOy' and Zn2+. Schuster and White <br />(28) in their study of diffuse vs. conduit aquifers found <br />that temperature, total hardness, pH and flow varied signifi- <br />cantly in the conduit aquifers. Of these parameters, total <br />hardness varied the most, sometimes the change being as large <br />as a factor of two. In a paper on implementing the EPA <br />effluent guidelines, Robins (33) suggests that total suspended <br />solids will be the most difficult to control. Drastic changes <br />in precipitation and runoff can rapidly change the load of <br />suspended_solids,_which makes the design of control equipment <br />difficult. From the above observations the following list <br />of tests can be dictated: <br />A. Basic Meteorological Tests <br />1. Air Temperature <br />2. Precipitation Amount <br />B. Basic Water Tests <br />1. Flow rate <br />2. pH <br />3. Conductivity and water temperature <br />C. Basic Effluent Tests <br />1. Total Suspended Solids <br />In the beginning of the analytical program, samples will <br />have to be sent to outside labs for total. characterization. <br />This will be dictated by the water release permit.
