Environmental Site Assessment Phases

A detailed investigation to define all known contaminants at a site and their spatial relationships, fully outlining pathways and receptors. This paves the way for remediation and risk assessment.

The process of bringing contaminated site media to acceptable levels based on regulatory standards. It involves outlining remedial options, evaluating them, and selecting the best solution based on criteria like cost, time frame, climate, and implementability.

The planning and design stage of remediation, where various options are identified, evaluated, and the most suitable solution is chosen based on specific criteria.

A detailed plan outlining the steps and strategies for remediation, including the chosen methods, technologies, and timelines.

A series of steps taken to address environmental contamination at a site, starting with preliminary assessment and ending with cleanup and monitoring.

A detailed plan outlining how to clean up a contaminated site.

The first step in assessing a site for environmental contamination.

A more detailed assessment of a site if contamination is suspected in Phase I.

An assessment that is needed to understand the extent of the contamination and impacts on the environment.

The phase where the site is monitored and evaluated for effectiveness of the remedial action.

A process used to determine the potential risks and benefits of different remediation options.

A detailed plan outlining the specific actions needed to remove the contamination.

A type of environmental protection measure that involves placing barriers to prevent soil erosion and sediment runoff.

A type of environmental protection measure that involves building small dams made of rocks to control the flow of water and prevent erosion.

A type of environmental protection measure that involves using hay bales to absorb water and prevent erosion.

A type of environmental protection measure that involves covering exposed soil with tarps or erosion control blankets to prevent erosion and sediment runoff.

A type of environmental protection measure that involves using pumps to remove excess water from construction areas to prevent flooding and soil erosion.

A type of environmental protection measure that involves using large rocks to protect shorelines and prevent erosion.

A type of environmental protection measure that involves using pads made of absorbent materials to soak up spills of oil and other hazardous liquids.

A type of environmental protection measure that involves using floating booms made of absorbent materials to contain and absorb spills of oil and other hazardous liquids on water surfaces.

When evaluating the feasibility of remediation technologies, this step involves estimating the capital and operational costs of different options. It helps determine which option is financially suitable for the client based on their budget and financial projections.

This tier assesses how the public views the proposed technology. For example, incineration, while effective, might face public resistance. This highlights the importance of considering public perception when choosing a remediation method.

This category physically removes the contaminant or contaminated medium from the site. This method doesn't require separation from the host medium. An example is excavation.

This category separates the contaminant from the host medium (soil or water). An example is Soil Vapour Extraction.

A process that physically removes the contaminant or contaminated medium from the site without the need for separation from the host medium. Example: Excavation

A process that removes the contaminant from the host medium (soil or water).Example: Soil Vapour Extraction

A process that breaks down or destroys the contaminant, rendering it harmless. Example: Bioremediation.

A process that limits the spread of the contaminant, preventing further damage. Example: Capping.

A small-scale laboratory experiment to determine the optimum conditions for a treatment method. It helps identify the time needed and provides cost estimates.

A larger-scale test conducted at the site to verify the effectiveness of the treatment method, address limiting factors, and refine design specifications.

The goal of a remediation plan is to achieve cleanup in a timely way, minimize disruption to nearby residents, meet environmental regulations, and be the most cost-effective option.

A method used in the remediation planning process to evaluate and select the most suitable treatment technologies. This includes bench and pilot scale tests.

A process that chemically or biologically breaks down contaminants into less harmful substances. Think of it like neutralizing a threat.

A method that prevents the spread of contaminants by physically blocking their movement. It's like putting a fence around a hazardous area.

A technique that involves using naturally occurring processes to clean up contamination, such as microbes breaking down pollutants. It's like letting nature do its work.

A method that introduces oxygen and nutrients to stimulate the growth of microorganisms that can break down contaminants. It's like feeding the natural cleanup crew.

A type of remediation that involves using air to remove volatile organic compounds (VOCs) from soil. It's like using a vacuum to suck up bad air.

A method that involves injecting air into the soil to promote the growth of microorganisms that can break down contaminants. It's like blowing air into the soil to help cleaners work faster.

A technology that mixes contaminated soil with specific materials to solidify or stabilize contaminants, making them less mobile. It's like turning something harmful into a solid, less harmful form.

A method that involves excavating contaminated soil and treating it in a controlled environment. It's like cleaning up the dirt outside and then treating it separately.

A process that uses heat to vaporize and remove contaminants from soil. Imagine baking the dirt to release the bad stuff.

A method that involves using special barriers to prevent the spread of contaminants. Think of this as putting a wall around a hazardous area to stop it from escaping.
