Your specialist Contaminated Land Consultant is part of a dedicated team of Chartered professionals who have been successfully gaining regulatory approval for clients all over the UK, ensuring that their sites are safe and compliant places to live and work.
Our Phase 2 Site Investigations are expertly prepared by experienced consultants who are committed to providing you with technically robust reports that are tailored to meet your plans for the site.
Our Consultants can review your site and guide you through the complex process of undertaking a Phase 2 Site Investigation, so you can get your site approved and built.
They are ready to get started.
Answer a few questions, so together we can come up with a plan that fits your timescales and budget.
We work through the complex process of organising the site works and carrying out the Phase 2 Site Investigation.
Site Investigation report written with a regulator in mind to gain approval, so you can take action to ensure a safe and compliant site.
A Phase 2 Site Investigation is the second stage of a phased Contaminated Land Assessment and involves intrusive excavation of the ground.
It is often required by local planning authorities to discharge planning conditions, remove objections and support planning applications.
A Phase 2 Site Investigation is only undertaken once a Phase 1 Desk Study has been completed and the preliminary risk assessment has clearly identified sources of contamination that warrant further investigation.
A Phase 2 Site Investigation typically involves the recovery of soil and groundwater samples from a site to analyse if contamination is present. The preliminary risk assessment is then reassessed based on any contamination that could be present.
A Phase 2 Site Investigation is the second stage of a phased contaminated land assessment that is often required to discharge planning conditions or remove objections, once planning permission has been granted. A Phase 2 is usually required following approval of a Phase 1 Desk Study, where potential sources of contamination have been identified, and the risks from which require further understanding.
In addition to supporting the planning process, a Phase 2 Site Investigation can also be used to:
The purpose of a Phase 2 Site Investigation is to physically inspect the condition of the soil, groundwater and surface water that may have been impacted by the sources of contamination identified in the Phase 1 Desk Study. The Phase 2 Site Investigation is site specific with the method(s) of investigation chosen being dependent on a number of factors, such as access, operational constraints, geology, potential contaminant sources and the receptors to be targeted (e.g. shallow soils, groundwater).
The most common methods of investigation employed during a Phase 2 Site Investigation may include:
Lustre Consulting prides themselves in designing cost effective and compliant investigations that effectively target contamination which could be in the subsurface and present a pollution risk. In most cases, it is also possible to combine the Phase 2 Site Investigation with a Geotechnical Investigation should further information be required on the engineering capacity of the ground to aid foundation design.
To meet your requirements and ensure you remain compliant, all our Phase 2 Site Investigations are carried out in accordance with current guidance such as the recommended approach set out in the Environment Agency’s Model Procedures for the Land Contamination Risk Management (LCRM) and the British Standard Code of Practice Investigation of Potentially Contaminated Sites (BS 10175: 2011).
All investigations are carried out by qualified and competent consultants who are experienced in the recovery of samples, in situ testing, soil logging and environmental monitoring to the British Standard Code of Practice for Site Investigation (BS 5939:1999). The findings are detailed in transparent and informative reports with clear and helpful conclusions and recommendations (if necessary) to carry out any required remediation.
Our Phase 2 Site Investigation reports regularly receive positive feedback from clients and regulators alike, and have been instrumental in successfully gaining planning permission and discharging conditions for a number of new development sites.
If your planning permission has conditions related to land contamination, a Phase 2 Site Investigation may be required as part of the planning process. It is a critical step in assessing any contamination risks identified during the Phase 1 Desk Study. It provides a more detailed, intrusive assessment of the site, including soil and groundwater sampling. The results help ensure that the site is safe for its intended use and complies with regulatory requirements. Without a Phase 2 investigation, there could be significant unknown risks that may result in costly delays or non-compliance issues during development.
If your Phase 1 Desk Study indicates the need for further assessment, a Phase 2 Site Investigation will be recommended. We always advise submitting the completed Phase 1 report to the local planning authority for their review before beginning the Phase 2 investigation. This step helps define the scope of testing required, ensuring that only necessary investigations are conducted.
Once the Phase 2 Site Investigation is completed, the results will be analysed to assess the levels of contamination on-site. If contaminants are present, a detailed risk assessment will be conducted to determine the impact on human health, water, and the environment. Depending on the findings, remediation work may be recommended, or further testing might be needed to address specific concerns.
Our contaminated land consultants can tailor the Phase 2 Site Investigation to account for restricted space or access issues. We have worked on a variety of challenging sites and can recommend suitable equipment or methods to overcome access limitations while still meeting the investigation’s objectives.
If your development will involve the disposal of soils, Waste Acceptance Criteria (WAC) testing may be required to classify the waste and determine its suitability for disposal in a landfill. WAC tests are now a standard requirement for most landfill sites. We can conduct WAC testing as part of the Phase 2 Site Investigation to ensure compliance and proper waste management.
Before commencing any site investigation, we ensure that all underground services are identified to avoid health and safety risks. If up-to-date plans aren’t available, we recommend requesting them from utility companies. In cases where timescales are tight, we can conduct a service clearance survey, which can be combined with a topographical survey if needed, ensuring no damage to underground utilities.
The timeline for a Phase 2 Site Investigation varies depending on the scale and complexity of the site. We typically require 1 to 2 weeks from the time of formal instruction to mobilise onsite. Following the site work, laboratory testing of soil and water samples usually takes an additional 1 to 2 weeks. Larger or more complex sites may require a longer investigation period.
Skipping a Phase 2 Site Investigation can lead to significant risks, including the discovery of unexpected contamination during construction, which may delay your project and increase costs. Without this assessment, local authorities may not grant approval for your development, or you may encounter compliance issues later on.
If you’re unsure whether a Phase 2 Site Investigation is required for your site, feel free to give us a call. We will discuss your project requirements, review your Phase 1 Desk Study, and advise you on whether a Phase 2 investigation is necessary. Alternatively, please send an email to info@lustreconsulting.com and provide us with the site location and description of the proposed development.
