RE: Radiation Potential at the Blue Pit in Garfield County, Colorado
I have been a professional engineer.in Colorado for 29 years and have had extensive experience
working with soils, radiation testing and uranium deposits in Colorado. The soils at the Blue pit
will have no issues with radiation for the following reasons:
1- The gravels located at the. Blue Pit are terrace gravels from hundreds of thousands of years of
erosion in the Roaring Fork River basin: There are no known uranium mines in this watershed,
to our knowledge.
2- Most uranium depsoits in Colorado form as carnotite in sedimentary rocks along ancient
stream channels in reducing environments. These are the sedimentary rocks of the Morrison
formation which were mined in other areas of the State. None of these sedimentary tacks exist
• in the terrace gravels of the Roaring Fork .River located at this site. Sedimentary rocks break
down and erode far more easily over thousands of years arid are generally not present in river
gravels. The deposit of gravel at the Blue Pit is clean and does not contain any uranium bearing
minerals to any extent of concern. The existing buildings have been in place for many years and
none have any problems with soil foundation issues.
Sincerely,
Greg Lewicki, P.E. Greg Lewicki and Associates
