CW(D) 540-2033 TO: DISTRIBUTION LIST Subject: MR7971 FINAL REPORT (PB BIOREMEDIATION) - ************************************************************************* * * * ALL RECIPIENTS: We would appreciate comments on the path forward on this study. Due to Bob's reassignment some time ago, we probably should not anticipate much more time from Bob, DOUG CREGAR: Please see note for "Page 7." Do you have 8,5"xll" site maps o*n**w**h*ic*h***lo*c*a**ti*o*n*s***co* *u*ld**b*e**m**a*r*k*e*d**fo**r**B*o*b*t*o***in*c*l*u*d*e*?***** ************* * * ** * with reference to the draft copy of the final report which you sent me in October, there have been few commentsl copy Please consider the following points (page numbers refer to your hard if t) : Page Should have a standard introduction with reference to MR7971 Parts X and II. This will add to the explanation of the "driving force" for the study Page 1 part I Approved 10/86 (covers study of Chambers Works NJ samples) Part II Approved 1/88 covers study of Beaumont TX samples) Needs a paragraph explaining why the "unamended" control was not a STERILIZED control (no sterilization method known which might not alter the existing groundwater Pb "profile" and or mimic bioremediation). Page 6. Lower center of page @ "Add 50ul Cresol red Indicator" -- O.lN NaOH solution is added? Page 7. -eAre locations and 32 separate from 3r> anH Si ma rked^sTTg""maps showing sampling 1 o c afT5ns( DC ures 2, 3, 4, 6, 7, and 8 Should we have CREGAR)? Plots would show effects better if they were stacked as DUP040004434 f* INSOLUBLE (final product) over SOLUBLE (intermediate product) over TEL (initial material) Page 10 Middle Paragraph with "PbR" equation -- should PbR be PbR+++? What does the comment "sulfate reducers channel electrons away from methane" mean? Is the intent to indicate that sulfate reducers withdraw electrons from the alkyl (ethyl) group R? Please :all if you have any questions. Richard DUP040004435
