Phase 1,2,3 and 4 Contaminated Land Reports
Phase 1 - This Phase 1 report is designed to give an overview of
the risks of contamination to end users and the immediate environment.
The report includes a walkover survey and a detailed look at the site
history and current use/setting. This report should be submitted to
the relevant Council authority for assessment prior to any further
investigations/analysis taking place on the property. Following this
submission, further reports/investigations may be required in order
to safely develop the property concerned.
Phase 2 - Further reporting on a site with potential problems should
be in the form of a Phase 2 Site Investigation Report. Should this
demonstrate that the site is not contaminated then no further works
will be required. If the Phase 2 report demonstrates that the site
is contaminated, further reporting and additional testing may be required
by the local authority and possibly the Environment Agency, before
the site development can progress.
Phase 3 - On completion of all the Phase 2 on-site testing works and in conjunction with confirmation of the final site layout, a Phase 3 Remediation Strategy Report should be completed to demonstrate how the site can be safely developed in respect of the end users. This will detail the methods to deal with each risk in respect of the property development.
Phase 4 - Following acceptance of the Phase 3 report by the appropriate
authority, a Phase 4 Verification Report will then be required as
the final report. This will be issued upon completion of the development
works in order to prove that the Phase 3 recommendations have been
carried out satisfactorily.
Waste Acceptance Criteria (WAC)
- Is your waste hazardous?
- Not sure of the correct course of action?
- If you are confused about 'WAC' testing, ASI can help you!
Disposing of Hazardous Waste
There are different routes for disposing of your hazardous waste:
Recycling - Treatment
- Transfer
- Soil Treatment
- Landfill
- Incineration
However, as the waste producer you are required to explore all options for the correct disposal route for your specific waste.
At ASI we can help guide you through the process, please call us for friendly, professional advice.
ASI UK offers comprehensive analysis and reporting for soil and water.
This can be as part of a Phase 2 report or as specific testing from
a single sample up to multiple samples for large, complex sites. Detailed
reports are produced with site maps, interpretation and recommendations.
Much of Cornwall suffers from a history of poor soils, principally due to its industrial heritage. This has resulted in many complications and heavy costs with regards new planning regulations. As such we are working with planning industry experts in developing a range of techniques, which will satisfy planning requirements and help to keep cost down.
Where a property is deemed at low risk from mining subsidence, it
is often appropriate to have a Structural Survey rather than a drilling
investigation. Structural surveys can cost as little as 15% of the
cost of drilling a property.
ASI UK can arrange for detailed structural surveys and arrange for any additional works that may be required to assess the property.
If you instruct a Structural Survey yourself, it is worth ensuring that the person you choose has the appropriate Chartered qualifications for assessing the structure of a building. ASI UK only uses Chartered Buildings Professionals for this type of work.
New development plots are often investigated for old mine workings
by excavating a series of trenches across the site, under the supervision
of a Mining Geologist.
Testing for further ground information such as soak-a-way testing, CBR (ground bearing capacity, etc. can also be arranged).
Where an existing property is deemed to be at risk from subsidence
due to old mine workings, the usual and most efficient method of assessment
is by rotary percussive drilling. A series of inclined holes are drilled
beneath the property to check for voids or backfilled mine workings.
If any mine workings are found, the next stage would be to assess the risk with an appropriate Chartered Buildings Professional (e.g. a Chartered Structural/Civil Engineer). Occasionally additional drilling may be required.
Drilling investigations are sometimes used for open plots, where trenching is not practical, possibly due to access restrictions.
Local authorities will sometimes require that a client carries out
an inspection of the foundation trenches prior to building works commencing.
This involves and examination of the completed excavations by a Mining Geologist to ensure that the trenches have not been excavated across old mine workings. A concise factual report is then produced for submission to the appropriate facility.
Mine Search Reports
ASI UK can arrange Desktop Mining Reports for properties throughout
the South West. Sometimes these are referred to as Metalliferous reports
or Mine Search reports.
Mining reports are considered mandatory for mortgage and insurance purposes for property conveyancing in old mining districts. These districts often cover larger areas than you might expect, with mining having occurred in Cornwall, Devon and Somerset.
If a property is shown to be at risk from subsidence or contamination due to historical mining activity, ASI UK has the resources and experience necessary to deal with any such problems.
