Monitoring - Kent
Introduction
GO Contaminated Land Solutions offer comprehensive monitoring services for property and land development projects in Kent. As seasoned professionals in the environmental industry, we understand the critical role that monitoring plays in ensuring the successful and sustainable completion of your projects.
At GO Contaminated Land Solutions, we specialise in monitoring soils, groundwater, and vapours to assess and mitigate potential risks associated with contaminated land. Our expert team of geologists, engineers, and environmental specialists are equipped with the in-depth knowledge to deliver accurate and reliable data.
On many projects remedial works are completed with placing of topsoil to gardens and soft landscaped areas. Of necessity this is happening near project completion and hand-over. By engaging us to undertake monitoring at key points during the remedial works you ensure a smooth process of verification and sign off. It is critical to avoid the potential for any last minute corrections where works have not met the strategy requirements for whatever reason.
With a focus on quality, efficiency, and sustainable practices, we aim to be your go-to partner for all your monitoring needs. Whether you're planning a new construction project or need ongoing monitoring services, GO Contaminated Land Solutions is here to ensure your project's success while protecting the environment and the well-being of the local community.
Monitoring of What?
Monitoring may be required for ground gases, vapours and groundwater levels and contamination. Monitoring of implementation of the remediation strategy may involve recording soils removed from and brought to site and any construction activity that could impact the functioning of the approved remedial works.
Why is this needed?
Monitoring may be required as an element of the Phase 2 investigation where more information may be found. Here we are looking at monitoring as a tool to demonstrate effective implementation of the remediation strategy.
The client, the local authority or the Environment Agency may require independent confirmation that the Remediation Strategy had been implemented correctly.
Without the appropriate records it may not be possible to complete the close out or verification report, which may result in delays and additional costs while further investigation is undertaken.
Groundwater
If there has been or is a risk of contamination of groundwater monitoring may well be required. It is important that groundwater is protected from contamination as this may end up in streams and rivers impacting wildlife or entering aquifers used as sources of drinking water.
Regular monitoring may be required where there is a risk that site activities, groundworks or piling may adversely impact the groundwater to ensure there are no adverse changes to the groundwater.
It may be that an old tank on site has been leaking into the groundwater. During and after removal of the tank groundwater monitoring will help to establish if the sole source of contamination has been removed or if there are others still to be located.
Vapours
Soils and groundwater contaminated by hydrocarbons will emit vapours. Monitoring for vapours will help to establish if the soil remedial works or groundwater treatment is effective.
Monitoring could be by means of standpipes in boreholes or in existing buildings by using VaporpinsTM, you can see installation in our video on vapour monitoring.
Soils
Many remediation projects involve the need to remove some soil and place a layer of clean soil across the soft landscaped areas. Monitoring will include:
- Measuring the depth and extent of any contaminated soil removal. On smaller sites a photographic record may be adequate on larger sites a topographical survey is likely to be required.
- Sampling the soil strata remaining on site and checking compliance with the remediation strategy.
- Checking the destination of materials removed from site and the source of material brought to site.
- Recording volume of contaminated soils and fill removed from site.
- Recording volume of clean soils brought onto site and once placed checking the depth and making a photographic record.
- Taking samples of soils brought to site to confirm compliance with the remediation strategy criteria.
- A photographic record of installation of any barriers or other works required.
In short recording sufficient information to enable a comprehensive Verification Report to be completed to demonstrate that the site is suitable for the proposed use.
