Dear Mr. Havel:

Thank you for speaking with me concerning the possibility of installinga groundwater monitoring well nest on your property. The well nestwould consist of two monitoring wells and would be installed as part ofthe monitoring program for the Ace Services site remedial efforts.

Black & Veatch Special Projects Corp. (BVSPC) is currently working as acontractor for Region VII of the U. S. Environmental Protection Agency(EPA). BVSPC is designing a remediation program for the chromium-contaminated groundwater plume associated with the Ace Services sitelocated 345 Convesse Avenue in Colby, Kansas.

Property records from the Thomas County appraisers office identify youas the owner of the property in which we would like to install agroundwater monitoring well nest. Two preferred proposed locations forthe well nest are illustrated on the enclosed aerial photos. The wellnest will consist of two monitoring wells located within 15 feet of eachother. Each well will be constructed to allow monitoring of a discretezone at approximately 220 feet and 175 feet depth. The monitoring wellswill help establish the size and concentration of the plume.

We will install the wells using rotary wash drilling techniques. Soilcuttings will be temporarily stored near the well head for approximately
