Re: Transmittal of chemical results from lead-screen auger borings,Conrail site, Elkhart, Indiana, Work Assignment J01-5L7Y

Dear Mr. Dalga:

Enclosed for your use are tables of chemical results from the lead-screen auger borings performed at the Conrail site during the PhaseII field vork. Also included is a map shoving the approximate loca-tions of these borings. All samples vere analyzed at the E & E fieldlaboratory in accordance with the method described in the QualityAssurance Project Plan prepared for the site.

You will notice that chloroform vas detected in many of the samplesanalyzed. Although this compound vas not Initially part of the pro-ject analytical parameters, it appeared on a number of the chromato-graphs. Our chemist vas able to quantify the chloroform concentra-tions, however these values are reported as estimates due to theless rigorous calibration that vas performed.

If you have any questions concerning this transmittal, please do nothesitate to call.

Sincerely,

Kevin H. Phillips VSite Manager
