Re : Consent Agreement and OrderDocket No. III-86-12-DCScovill Site at Montross, Virginia

Dear Walter:

The purpose of this letter is to transmit soil data which we obtainedsubsequent to our September 19 letter report to you. In accordance with ourrecommendation in that letter, ICF Technology resampled soils in the old pondin order to verify the presence of elevated concentrations of lead that hadbeen reported in an initial sample; viz., TCLP of the 0-6 inch compositesample from the west side of the old pond bottom (collected on August 26) wasreported to have a TCLP concentration of lead of 3,200 ug/1.

On October 5, ICF Technology collected a composite sample from the westside of the old pond using a hand auger. Soils were taken from the same fivegrid units used on August 26 and from locations as close as possible to theoriginal auger holes. The sample was then placed in an ice filled cooler andsubmitted to Versar for TCLP analysis. As shown in the attached laboratorydata report, no lead was detected in the October 5 sample.

This resampling result, in conjunction with the fact that no otherelevated concentrations of lead were detected in the old pond, indicate to .usthat lead is not a problem in the old pond soils. The result confirms oursuspicions that the 3,200 ug/1 concentration was an anomaly, perhaps occurringduring laboratory analysis. As a result, no additional soil removal isproposed for the old pond prior to backfilling.

I am requesting your approval of this decision as soon as possible as weintend to proceed with earthwork at the site sometime in the next week.

Sincerely yours,

Gary N. /DietrichSenior Vice President

This batch of one soil was received on October 7, 1988 fornination of lead. The sample was extracted on October 1Oding to Toxicity Characteristic Leachate Procedure (Federalter, Vol.51 #216,Part 268>. The extract was digested andzed by ICP on October 12. Both digestion and analysiswed methods outlined in SW-846, 3rd. Edition. As requested,was performed on the sample. All blanks were clean and allstandard recoveries were within 1054 control windows.
