Dear Dr. Wogman:
I have reviewed your monthly report for the Edgemont Cleanup Action Program (B_2217) for flarch,1982, and have the following comments:
1)
You are authorized to complete the screening surveys at those residences which recently requested such surveys. Also, you should continue to complete all full-engineering assessments as soon as possible.
2)
Your evaluation of the mini _ engineering assessment protocol with respect to the lack of correlation between the maximum radium.226 content of soil detected to the grab Working Level measurements was acceptable.
I agree with your conclusion that based on the existing Edgemont data, one cannot predict the radon progeny exposure level in a structure given the radium content of soil surrounding it.
This does not mean'that the mini-EA is not capable " locating deposits of residual radioactivity at a property; L
'ther, that a more extensive research program would have to be con.c bed to assure a statistically valid interpretation of the soil and borehole sanpling results.
Such a research program is beyond the scope of this contract. Therefore, you are directed to discontinue the
$ @a:
mini-EA program and to finalize your evaluation as contained in your March, 1982 letter report.

3)
Your RPISU summary report as detailed in my February 2,1982 letter to you should be completed and reported no later than your May,1982
+
monthly letter report.

^
40/GGE/82/04/22/0 gg 3 g g authorized in item 1) above, you are directed to complete the remaining radiological surveys at all properties for which permission has been granted. You are also hereby directed to personally contact each homeowner for those few cases where the owner refused the survey and signed the legal release form, or accepted the survey but failed to return the legal release form, or for the "not delivered" category, in order to urge such homeowners to grant permission to have the free radiological surveys completed.
5)
Your summary tables for the grab Working Level Surveys and the Lot Surveys were acceptable.
You may finalize your Table IV.
Mini-Engineering Assessments as directed 17 item 2) above.
6)
I have received the draft copy of eleven ARIX, Inc.
architect-engineer survey blueprints but have not to date received the ARIX specification letters. Please forward all such draft and final ARIX blueprints and specification letters for my review and comment. As we have previously discussed and agreed to, there is no need to prepare detailed blueprints for those few properties which have minimal residual radioactivity present (e.g., tailings used in sandbox or as bedding material in flower box) and for which a descriptive specification letter can be prepared to adequately describe the necessary remedial action required to remove such radioactivity.
7)
Your Financial Statement was acceptable.
8)
As we agreed to, in order to provide a more comprehensive 1981 annual report for this contract (B-2217), your first draft should be provided to me no later than April 30, 1982.
All other aspects of your March,1982 report were acceptable. The actions taken in this letter are considered to be within the scope of the current contract (B-2217). No changes to costs or delivery of contract DIST:
