Phase II Investigation Of Former Waste Treatment Plant

Caltha LLP Project Summary

Project: Phase II Investigation For Former WWTP Site 
Client: Prospective Buyer  
Location(s): Minneapolis / Saint Paul, Minnesota Metropolitan Area

Key Elements: Phase 2 Site investigation, GPRS, Ground Penetrating Radar, Wastewater treatment facility

Overview: Caltha LLP conducted a Phase 2 Environmental Site Assessment for this property located in suburban Minneapolis / St Paul which was the historical location of a wastewater treatment plant (WWTP) and wastewater sludge management facilities. The property had been the site of a WWTP dating from 1965 through the 1980s. The WWTP and associated sludge handling facilities had been abandoned and demolished approximately 40 years ago. However, it was determined that some wastes and underground structures associated with the wastewater facility may have be disposed of or abandoned on-site.

 The focus of the Phase II Investigation was to determine if wastes and abandoned structures remained on the property which could represent Recognized Environmental Conditions and potentially impact the future use of the property. The investigation includes a Ground Penetrating Radar Survey within the area of the former WWTP identified in historical aerial photographs and a Trenching Investigation in areas of the former sludge drying basins.
