| Former SunarHauserman Site Redevelopment (Lutherwood Village) | |
| Start Date: | 1/1/1989 |
| End Date: | 1/1/2003 |
| Location: | 1 Sunshine Avenue, Waterloo, Ontario |
| Project Scale: | Completed, Monitored. |
| Media Treated: | Soil, Liquid. |
| Clean up of Site Involved: | Treatment, Removal. |
| Site Condition: |
(28.9 acres) Formerly a large steel-product manufacturing facility in operation for over seventy years, the SunarHauserman factory was an environmental challenge in the heart of Waterloos uptown core. In the early 1990s the site was abandoned after the company went bankrupt, and the property came into the hands of TransAmerica Life, who found that the site had many environmental and planning challenges. The subsurface investigations on this site found elevated concentrations of trichloroethylene (TCE) and other related compounds in the groundwater within a confined aquifer beneath one area of the site. The TCE concentrations found in groundwater samples from the confined aquifer ranged in concentration from about 3,500 ppb to 15,000 ppb. Other related compounds that were present included cis-1,2-dichloroethylene (c-1,2-DCE), which ranged in concentration from about 1,300 ppb to 14,000 ppb, and vinyl chloride (VC), which ranged in concentration from about 300 ppb to 5,400 ppb.The confined drinking water aquifer consists of a layer of primarily sand, which is overlain by an aquitard of silty clay till about 5 to 15 metres thick, which in turn is overlain by a surficial aquifer unit of granular soils about 5 to 10 metres thick. |
| Proposed Site Usage: | Unique Seniors Village with an ideal location adjacent to Westmount Mall, a community commercial facility, and the City of Waterloo Recreation Centre: 5 storey 155 unit seniors complex, 76 retirement bungalow townhomes, 10,000 sq.ft. single storey community space, and Kitchen facilities to service cafeteria. Other proposed usages for this large site include: new frontage onto Waterloo Park (1,600 feet); extension of several roadways to allow access and parking reconfiguration to Westmount Mall; a 5% (1.45 acre) park dedication, expansion of the Citys Recreation Complex lands; 3.1 acres purchased by the City for the future twinning of the area in the Recreation Complex; 2.1 acres was purchased by the City to extend the southern boundary of Waterloo Park and a redundant portion of Sunshine Avenue was closed. |
| Reasons for Success: |
During the process, public and private interests were satisfied such that: a large deserted industrial site was decommissioned and redeveloped in accordance with the Ministry of the Environments Guideline for Clean-up of Contaminated Sites in Ontario and now compliments the Citys vision for the uptown neighborhood; a Purchase/Sale Agreement and Site Remediation Plan were negotiated between the seller, TransAmerica Life, and the developer. These were supported by the MOE and the City, allowing the sale and development to proceed, while the seller retained liability for the costs of completing a long-term groundwater remediation program to the satisfaction of the MOE; seniors in the north end of Waterloo Region now have a residential option providing a continuum of care, choice and a sense of community.Through separate agreements with the developer, the City achieved the following: Father David Bauer Drive was successfully extended to Westmount Road, improving traffic and access patterns to this area of Waterloo; the City secured land required to provide for the future expansion of the Citys recreation complex; and additional land obtained by the City provided a new southern boundary to Waterloo Park with the creation of 1,600 feet of new road frontage. XCG added value during this project in several ways, starting back at the Phase I, but primarily by virtually ""saving the deal"" between Transamerica and the eventual purchaser (Lutherwood) when at one meeting in August 1995, they concluded that they would not be able to characterize the off-site contamination in time to get MOEE ""buy-in"" to a remediation plan. At that meeting, XCG stated that it could be done. |

Technologies Used: |
Site decommissioning included: removal of an underground storage tank (UST) for solvents; removal of 800 tonnes of leachate toxic soil on the east side of the property; and removal of 1,000 tonnes of non-hazardous waste along the previous rail spur line. Additional test wells encountered sporadic low-level findings of TCE. It was determined that the deep aquifer was protected by a clay-till aquatard. A pump-and-treat program (agreed to with the MOE and the Regional Municipality of Waterloo) is completing site cleanup. On the basis of XCGs review, a pump-and-treat system using an AOP unit as the groundwater treatment process was found to be the most cost-effective solution that was acceptable to the regulatory authorities who were involved with the site (mainly because of the proximity of the water supply well). |

Description: Transamerica had acquired this property as a result of a foreclosure, and required decommissioning and demolition prior to being sold and redeveloped. In addition to the subsurface investigations, XCG also completed a designated substances and hazardous materials survey of the building structure on the property, prior to building demolition. Work done included the demolition of the existing 307,000 square feet of industrial building and decommissioning of an industrial property. Environmental cleanup included extensive lead paint, asbestos, PCBs, solvents and fuel tanks, as well as cleaning up buried paint wastes, hydrocarbon impacted soil and solvent impacted groundwater. Rail spur lines connected to the main rail line to the east and transected a portion of the site had to be addressed. |
