As you can see from the picture, the testing of air quality in downtown Boulder began this week and will continue thru July. Due to an injury to the Principal of Quality Environmental Services, our project will be led solely by Dr. Shelly Miller. Dr. Miller is a Professor in the Environmental Engineering Program at the University Of Colorado and a published expert in Urban Air Quality. She will be assisted by Graduate Students in Environmental Engineering. We are extremely fortunate to have Dr. Miller leading this work and the final product will have the benefit of her outstanding credentials. We are very grateful for the assistance of Dr. Miller's talented graduate students. We will be contacting all contributors asking that they write replacement checks payable to "University Of Colorado". Your contributions now will be TAX DEDUCTIBLE! We will destroy the old checks that were payable to "Quality Environmental Services" and have not been deposited. Please mail the replacement checks to Preston Padden, 1301 Canyon Blvd #306, Boulder, CO 80302. Thanks very much.
