  1. Phase 1 ESA Report Red River Co-op Ltd Service Station 1084 Ellice Ave, Winnipeg, MB MB Contaminated Sites File 20709

  2. Written and Presented By: Students of Soils 4500, Ltd. (SOS) to members of the community at the University of Manitoba • Stacie Westervelt • Daniel Seburn • Tyler White • Chris Hope • Sachelle Johnston

  3. Purpose and Use • Phase I ESA report on Red River Coop and Gas Bar at 1084 Ellice Avenue in Winnipeg • On behalf of Mr. Francis Svomuya in consideration of plans to purchase and redevelop site as a restaurant. • In accordance with Contaminated Sites Remediation and Consequential Amendments Act of Manitoba

  4. Land Use

  5. Land Use

  6. Historical Land Use Undeveloped until 1908 1908-1961: Used as a coal yard

  7. Historical Land Use 1961: Co-op Credit Union & Store 910 Wall Street 1966: Safeway 1972: Domo 1994: address change to 1084 Ellice

  8. Historical Land Use Before reconstruction After reconstruction

  9. Potential Contaminants Gas Station: • Lead • Petroleum hydrocarbons Coal Yard: Mercury Polycyclic aromatic hydrocarbons

  10. Contaminants • CoalYard • Polycyclic Aromatic Hydrocarbons (PAH) • Mercury • GasStation • Petroleum Hydrocarbons (Benzene) • Lead

  11. Contaminants Benzene • Most likely contaminant due to fuel leakage • Remains sorbed to soil (especially with high organic matter content) • Carcinogen Lead • Gasoline lead regulations enforced in 1990- almost 20 years after our site began selling gasoline • Cumulative poison in humans • Developmental problems, seizures, can be fatal

  12. Contaminants PAHs • Occur as mixtures- difficult to characterize • Can be persistent • Many are known carcinogens Mercury • Leaching during rainfall • Adsorption to soil most likely fate • neurotoxin

  13. Site Characteristics - Ellice Co-Op in relation to major rivers of Winnipeg

  14. Soil Types and Hydrology • As per Soil Map Reconnaissance Survey of Winnipeg Area, general soil at our site consists of fine textured shallow lacustrine deposits on till • Main Winnipeg aquifer is retained in the upper fifty feetof the thick underlying limestone layer • aquifers permeability is very low in the central area of the city compared to most other areas within Winnipeg • With respect to potential contaminant migration to surrounding sites and down to the aquifer, the hydraulic conductivity of the clay soil around our site is relatively low • Aquifer not used as drinking water source in Winnipeg

  15. Drainage • Site located within the combined land drainage and sanitary system of Winnipeg • With respect to contaminant flow, would mean that surface spills, underground tank leaks, and disposal of chemicals through on site drains would all result in contaminants reaching the sewage system

  16. Zoning - Site in relation to surrounding residential and industrial/commercial zones

  17. Zoning Information - The Red River Co-Op at 1084 Ellice has a valid petroleum storage permit (file number 25306) expiring 31/12/2015 as per Manitoba Conservations registered tanks program.

  18. Site Plan

  19. Conceptual SPR Model

  20. Sources – Coal Yard • As a former coal yard, it is likely that any depositions, precipitation, weathering, and erosion would have left contaminants such as Mercury and polycyclic aromatic hydrocarbons (PAH’s). These compounds were introduced decades ago, but tend to persist for a long time within the soil.

  21. Sources – The pump & tank Spills Over-filling and faulty gas/diesel pumps, as well as leaks in holding tanks directly introduce petroleum contaminants such as hydrocarbons, lead, methanol, ethylene glycol, benzene, toluene, xylene, methyl tert-butyl ether, and napthalene.

  22. Day to Day operations • Daily operations have a wide array of potential contaminants including phosphates, waste, idling engines, engine coolants, washer fluids, and possible propane leaks.

  23. Pathways - Air • A major pathway for contaminants is through the combustion of gasoline and diesel engines are responsible for directly inputting CO2 emissions, propane, penzene, toluene, xylene, methyl tert-butyl ether, and naphthalene. One common means of air transport is from wind. Also, direct transfer of combustion particulates from exhaust, as well as erosion of surface soil. Weather conditions can also play a role, as transportation through evapo-transpiration resulting from heat, or solar radiation allows for movement of particulates.

  24. Pathways - Soil • The pathways amongst soil contamination are largely due to erosion, sedimentation, and groundwater flow. Erosions from sun, wind, or other environmental factors allows for movement of previously undisturbed contaminants. Groundwater also transfer sediments underground, re-depositing the contaminants in various location. This is largely dependent and topography, terrain, and precipitation. Lastly, construction processes such as excavation expose deep soil, allowing for easier transfers.

  25. Pathways - Water • The main pathway for water is through various forms of precipitation. This involves the process of evapotranspiration, which upon condensation, returns to the ground and water through varying forms of precipitation. Also, runoff and groundwater flow are responsible for moving much of the larger particulates across areas over time. Once in the water system, contaminants are readily dispersed.

  26. Receptors • There are many scales when looking at receptors. From micro-organisms, aquatic species, vertebrates and invertebrates, all can be affected by fuel station contaminants. Direct contamination of soils allows for micro bacterial organisms within the soil to be exposed to highly toxic levels of exposure. Also, air pollution poses varying levels of toxicity to all living organisms it comes in contact with.

  27. Receptors – humans • Oral ingestion of contaminated site includes consumption of fish within waterways, as well any consumption of primary producers within contaminated soils. • Inhalation of contaminated vapors and particulates in the air • Dermal exposure • Daily intake of fluid • Intake of animals depending on contaminated areas

  28. Receptors • Receptors will vary based on proximity, frequency, and duration of exposure from contaminants. Toxicity as well as bio-concentration and bio-accumulation are important to identify when determining risk levels.

  29. Site Visit - Fuel Pumping Stations along northern side of property, shot facing south west

  30. Site Visit

  31. Site Visit - Automatic Car Wash exit and location of Major Sewage Drain (just off photo)

  32. Site Visit -Boulevard grasses and shrubs only vegetation on site -No visual indication of stained soil, almost entire property covered in concrete - Soil on north-west corner of property – Boulevard along eastern edge of property (along Wall), shot facing south

  33. Site Visit – East side of Convenience Store, Vacuum Station, and Large Propane Tank

  34. Limitations!

  35. Limitations • No help from staff or management on site • Manager unable to provide any useful information • Unable to obtain permission to view some areas • Frequent address changes and no good available records • 1084 Ellice did not exist until 1994 • Several address changes through site history with no good available records

  36. Conclusions • Based on results of Phase I ESA, there are no immediate and obvious areas of concern. • However, the limitations presented mean that contamination can not be ruled out. • Therefore client is advised to conduct further investigation in the form of a Phase II ESA.
