Q&A about soil remediation work at Old Town Hall

61 Main Street – Soil Remediation Plan

Q1 – Why is this remediation project being conducted?
A – The City of Ottawa has conducted several environmental investigations at 61 Main Street to characterize soil and groundwater quality at the site. The site assessments identified elevated levels of several polycyclic aromatic hydrocarbons (PAHs) in surface and subsurface fill material at concentrations exceeding the Ontario Ministry of the Environment (MOE) 2011 Table 3 Site Condition Standards for residential/parkland/institutional land use and coarse textured soil. In order to address the PAHs found in the soil at the site, the city’s Environmental Remediation Unit will be undertaking a remedial program that will involve removal of all exposed shallow soil to a depth of 30 cm across the site, and replacement with a non-woven geotextile layer and cap of clean soil/grass or playground sand. This project is being undertaken in conjunction with the addition of a new accessibility ramp at the facility that will be constructed during August and September 2014.

Q2 – What are PAHs?
A – Polycyclic Aromatic Hydrocarbons (PAHs) are a group of more than 100 chemicals that are produced during the incomplete burning of fuels, garbage or other organic substances such as tobacco, plant material or charbroiled meats. PAHs are also contained in asphalt, crude oil, coal,
coal tar pitch, creosote and roofing tar, and are found throughout the environment in the air, water and soil. They can occur in the air, attached to dust particles, or as solids in soil or sediment.
