Testing should be for total sulfur by the <br />Deco furnace method, pyritic sulfur and sulfate sulfur as cvell <br />as the neutralizing potential. Testing should proceed icr both <br />rinsed and unrinsed samples. <br />Leach ili y_Testing <br />The unrinsed samples should be tested for leachability. <br />Follow the FPA 1312 test procedures for this material. The <br />leachate should be tested for the following parameters: <br />Conductivity, total dissolved solids, major catiot1s and <br />anions, alkalinity, total cyanide, WAD cyanide, arsenic, <br />barium, boron, cadmium, calcium, chromium, copper, iron, <br />lead, magnesium, manganese, mercury, molybdenum, nickel, <br />potassium, selenitun, silver, and zinc. <br />All metals tenting should be for dissolved testing. <br />we will not proceed with humidity cell testing unlexs the <br />results of the ANP/AGP indicate a change from the previous <br />sample results. We will evaluate the ANP/A.GP results when they <br />are received and notify CORE if we want to proceed with the <br />humidify cell testing. <br />When we spoke on the telephone I was not sure of the <br />amount of pore water that we would be able to obtain from each <br />sample. Alana first obtained water and preserved this water <br />with hydroxide for analysis of weak acid dissociable cyanide. <br />If sufficient sample is available for total cyanide, please <br />oomplete this test as well. We need at a minimum thr. WAD <br />values, even if you need to qualify these numbers dtae to <br />inadequate sample to complete your QA/QC program. <br />Alana obtained some additional water and preserved this <br />with nitric acid for metals analysis. The liquid should be <br />tested for arsenic, bariut~, baron, cadmium, calcium, chromium, <br />copper, iron, lead, mercury, magnesium,manganese, molybdenum, <br />nickel, potassium, selenium, silver, sodium, and zinc. All <br />metals should be tested for dissolved metals. we are not sure <br />if there is sufficient sample for metals analysis. oncca you <br />have an opportunity to review the amount of water available for <br />
