Site Location: Alpena, Michigan
Project Dates: 10/99 – 4/00

Sagasser & Associates, Inc. was subcontracted by a State of Michigan Level of Effort (LOE) firm to complete airborne particulate monitoring at this Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Site. The project involved the preparation and collection of particulate samples, on an on-call basis (quick response), resulting from a cement kiln dust (CKD) pile.

The Site is a former concrete production facility and is adjacent to an active limestone mining and processing facility. Cement kiln dust (CKD), a byproduct of cement production, was staged on an approximate 80-acre waste pile along the shoreline of Lake Huron. The CKD is known to have leached/migrated into Lake Huron. Sagasser & Associates, Inc. completed airborne particulate monitoring utilizing laboratory protocol for the Collection of Airborne Fallout Samples Using Direct Deposition Passive Monitoring to evaluate the potential for CKD to become airborne resulting in off-Site migration/impact.

Sagasser & Associates, Inc. was responsible for preparing sample containers, securing prepared sample containers within a lock box, thoroughly documenting sample handling via custody logs, contacting the project meteorologist upon arrival to the Site to evaluate sample locations based weather and wind direction as determined from on-Site observations and an on-Site meteorological tower, setting samples, and collecting the samples for subsequent direct transportation to a laboratory representative. Sample collection included placing the sample containers at select air monitoring (AM) points located around the perimeter of the CKD pile and allowing airborne particulates to collect on conductive tape located within the sample container.
