Consistent with the terms of <br /> the FFA (the Agreement) EPA is providing comments within 30 days <br /> of receipt of the deliverable. <br /> EPA's primary concerns are (1) the potential for cross- <br /> contamination between aquifers both before and during well <br /> abandonment, (2) uncertainty regarding purge methods, and (3) the <br /> need for sampling to be conducted in a manner consistent with EPA <br /> and state procedures since further sampling at these wells will <br /> not be possible once abandonment is complete. <br /> Please call me at (415) 744-2392 if you have further <br /> questions. <br /> Sincerely, <br /> " <br /> V Y U W.Gtf.� "C/G�✓t' <br /> Michael Work <br /> Project Manager (H-7-3) <br /> Federal Enforcement Section I <br /> Superfund Enforcement Branch <br /> Attachment <br /> cc: (see distribution list) <br /> Printed on Reroeled Paper <br />
