WARD, C&P CHAMBERS WORKS FROM: BOB FALLON, HASKELL RE: RESULTS FROM FIRST LEAD ANALYSIS CC: D. CREGAR, E. LESER JOHN DOMENICO SENT RESULTS FROM OUR FIRST ATTEMPT AT LEAD ANALYSIS AT HASKELL. TWENTY ML WELL WATER SAMPLES IN TRIPLICATE WERE CARRIED THROUGH THE FRACTIONATION SCHEME PREVIOUSLY OUTLINED. IN ADDITION, THREE TOTAL LEAD SAMPLES FROM THE SAME BATCH OF WATER WERE ANALYSED. THIS WATER WAS FROM WELL #31, THE SAMPLE WITH THE HIGHER CONCENTRATION OF THE TWO WE COLLECTED. THIS WELL WAS REPORTED TO HAVE TOTAL LEAD CONCENTRATIONS OF 2.2 PPM WITH 0.5 PPM ORGANIC LEAD IN THE DATA ERNIE FORWARDED TO ME (WELL 0W-TEL-3D). RESULTS ARE AS FOLLOWS: SAMPLE TOTAL #1 TOTAL #2 TOTAL #3 LEAD CONC. x VOL. OR WEIGHT 0.391 MG/ L 0.023 L 0.415 0.020 L 0.422 " 0.022 L = LEAD IN FRACTION 9 UG 8.3 UG 9.3 UG MEAN = 8.9 UG OR IN A 20 ML SAMPLE 0.443 PPM TOTAL LEAD FRACTIONATED TEL INS0L(PH9) S0L(PH9) B TEL INSOL(PH9) S0L(PH9) 0.217 MG/L 0.013 MG/100G 0.084 MG/L 0.228 MG/L 0.006 MG/100G 0.142 MG/L 0.035 L 14.1 GM 0.019 L 0.035 L 13.1 GM 0.019 L TOTAL = 11.0 UG 7.6 UG 1.8 UG 1.6 UG TOTAL = 11.5 UG 8 UG 0.8 UG 2.7 UG DUP040004400 TEL INS0L(PH9) S0L(PH9) 0.160 MG/L 0.044 MG/100G 0.152 MG/L 0.035 L 11.1 GM 0.019 L 5.6 UG 4.8 UG 2.9 UG TOTAL 13.3 UG MEAN FOR TOTAL LEAD IN FRACTIONATED SAMPLE = 11.9 UG OR 0.597 PPM IN 20 ML SAMPLE DISTILLED WATER GLASSWARE RINSE 0.084 MG/L IN A 70 ML SAMPLE. IP ALL WAS DISSOLVED IN 20 ML THIS WOULD EQUAL A CONCENTRATION OF 0.294 PPM. CONSIDERING THAT THIS IS THE FIRST TIME WE HAVE WORKED WITH LEAD ANALYSIS AT HASKELL AND THAT WE MADE ONLY MODERATE GLASS WARE CLEAN UP EFFORTS, I AM VERY ENCOURAGED BY THE RESULTS. SINCE WE WILL BE LOOKING FOR MOVEMENT OF LEAD FROM THE ORGANIC FRACTIONS (TEL + SOL LEAD) TO THE INORGANIC FRACTION (INSOL. LEAD), WE WILL BE MEASURING LOSS FROM THE POOL THAT ALWAYS MAKES UP 60% OR MORE OF THE TOTAL LEAD AND WE SHOULD HAVE REASONABLY GOOD SENSITIVITY TO CHANGES. THEREFORE, I DON'T SEE LEAD ANALYSIS AS A SIGNIFICANT PROBLEM IN THE TEL PROJECT, EVEN THOUGH WE WILL BE WORKING WITH LEAD LEVELS 10-100X LOWER THAN ORIGINALLY DISCUSSED. PLEASE LET ME KNOW IF ALL PARTIES AT CHAMBERS WORKS AGREE WITH THIS EVALUATION. DUP040004401
