"Cleaning up the past
: By the end of June, 31 tons of contaminated soil will have been removed from the Como Student Community Cooperative. The story of the contamination traces back to an era when the link between environment and health was unknown"
By Mike Mullen, The Minnesota Daily (5/4/10)
excerpt -- "On Sept. 18, 2008, the phone rang in Janet Dalgleish's basement office at Boynton Health Service. Dalgleish, the University of Minnesota environmental affairs coordinator, was told that construction workers at the Como Student Community Cooperative had been waterproofing one of the buildings when they found ash, stained soil and debris. They immediately stopped working.
In the days and months that followed, lab tests revealed that the soil around three CSCC apartments, which are University-owned and tailored to married graduate students, was contaminated with alarming levels of cadmium, lead and carcinogens. As Dalgleish saw it, the University could either dig up and replace millions of pounds of soil or close three apartment buildings. “It wasn’t acceptable to do nothing,” Dalgleish said. “That was not one of the choices.” . . ."
- Waterproofing -- Last fall waterproofing of buildings 5, 6, 10 and 11 was completed. During waterproofing of Building 11, soil contamination was found. The soil involved in waterproofing was remediated, and further testing planned for the spring. This spring it was determined that there was widespread contamination at the north east section of the property. Remediation and waterproofing of buildings 12 and 13 is being planned.
- Soil Contamination -- Soil contamination with various industrial contaminants was found around buildings 11, 12 and 13. The University obtained a grant from Hennepin County to help with remediation of the soil, and will bid out the remediation project after receiving those funds. The cost of this project is affecting the timing of other major projects, such as the renovation of parking lot D and possibly coreway renovation. In addition, soil contamination could preclude the digging necessary to install pavers in parking lot D.
From the General Manager’s Annual Report to Stockholders June 2, 2009 section (page 17), submitted by Jerry Erickson
- ". . . Our unforseen water proofing project begun a few years ago was nearing completion on the final three buildings when contaminated soil was discovered. Removal of the soil around buildings 11, 12 & 13 will now have to be done at a depth of from three to six feet. Since Hennepin County will be providing some clean-up funds, it looks like some of the soil remediation will be done late this summer and the remainder next summer, 2010. This will have to be coordinated with the remaining water proofing of buildings 12 & 13. "
Project Name: Como Student Community Housing - rebuild parking lot D
Project #: 01-151-11-1419
Estimated Construction Budget: $425,000
Anticipated Award Date: 7-13-11
Vendor Identified Risks . . .
6) If the University’s contaminated soil excavation contractor fails to correct the required areas to meet the schedule. This would appose a risk of completing the project on time.
8) Encounter greater volume of contaminated soils.
17) The Como Student Housing site is known to contain contaminated soils and possibly poses a risk to workers and residents if disturbed not contained.
21) Because of the soil remediation work taking place, electrical feeds and conduit that would typically be re-used are going to have to be new.
