What is a Phase 3 Remediation?
A Phase 3 Remediation is an essential step to ensure that contaminated land can be developed safely, with minimal risk to human health. It provides clear, targeted and evidence-based approaches to breaking the linkage between pollutant sources, pathways and receptors on your site.
A Phase 3 Remediation Strategy is the next step in the contaminated land assessment process, following a Phase 1 Desk Survey and Phase 2 Site Investigation. Once the site investigation has identified the nature and severity of any contaminants, the remediation strategy ensures these are dealt with in a fully compliant and safe manner.
Do I need a Phase 3 Remediation?
If a Phase 2 Site Investigation report has found that there is an unacceptable risk to human health or the environment on your site, then the Local Planning Authority will require you to produce a Phase 3 Remediation Strategy.
This strategy must clearly explain how the contamination at the site will be dealt with to mitigate those risks.
What is involved in a Phase 3 Remediation?
A Phase 3 Remediation will:
- Use the findings from the Phase 1 Desk Study and Phase 2 Site Investigation to determine the options available to remediate the site.
- State how these options will mitigate the risks to human health and the environment from the contaminants identified.
- Meet any regulatory requirements.
- Identify the most suitable and cost effective remediation options for your site.
- Define the roles and responsibilities of all parties involved in the remediation.
What factors affect a Phase 3 Remediation?
It is essential that a Phase 3 Remediation is fully tailored to the specific challenges your site is facing.
The strategies we recommend will be shaped by a range of factors, including:
- The location, extent and severity of the contamination present.
- The specific source-pathway-receptor linkages.
- The nature of the risks posed to human life.
- Any time and cost constraints of your project.
- The intended end-use of the land.
- By carefully considering these and other factors, our expert team of technicians can deliver a Phase 3 Remediation Strategy that provides a clear roadmap for a successful remediation project.
What are the most common remediation strategies?
The remediation strategies recommended for your site will depend on the nature, extent and severity of the contaminants present. Common remediation strategies include:
- Bioremediation. A cost-effective and environmentally friendly method that uses microorganisms to break down hydrocarbons in contaminated soil and groundwater.
- Encapsulation of contaminated soil. A method that involves isolating the contaminated soil using hard-surfacing materials.
- Pump and treat. A groundwater remediation technique that involves removing contaminated groundwater from the soil using pumps and then treating it at the surface.
- Monitored natural attenuation (MNA). A remediation method that uses natural biological, chemical, and physical processes to reduce the concentration of contaminants.
- Dig and dump. Also known as excavation or disposal remediation, this method involves removing contaminated soil from a site and disposing of it in a landfill.
- In-situ remediation. A subsurface remediation technique that helps prevent toxic substances from reaching drinking water wells or surface waters.
FAQs
- How much will a Phase 3 Remediation Strategy cost?
The cost of a Phase 3 Remediation Strategy will depend on the specifics of your project. This includes the size of your site, the nature and extent of any contaminants, and the specific source-pathway-receptor linkages that need to be tackled.
