Site Walkover Surveys

Our engineers have been out of the office completing multiple Site Walkover Surveys in recent weeks.  The surveys are completed as part of our Phase 1 Desk Study services, and form an integral part of our Phase 1 Desk Study reports.  The purpose of the survey is to basically see a site in the flesh, to identify potential sources of contamination that could impact land and the surrounding environment, such as Above Ground Storage Tanks (ASTs), Underground Storage Tanks (USTs), pipelines, chemical storage areas, general site use etc.

Our engineers complete a pro-forma questionnaire for each site and take photographs that help to inform our reports and ultimately the sites Conceptual Model.  As well as contamination sources, other relevant details such as off site use, site access, building layouts, evidence of staining/vegetation die back, hummocky ground that could indicate buried wastes, presence of drainage/oil interceptors, site topography etc is checked and recorded.

It is essential that a site walkover survey is completed to inform a Phase 1 Desk Study report, as for obvious reasons the report is not compliant with UK Best Practice and relevant guidance, such as the EA/Defra document “CLR11 Model Procedures for the Management of Land Contamination“.  You cannot risk assess a site properly without seeing it and reconciling it with features identified during the historical review of Ordnance Survey mapping, also completed as part of the Phase 1 reporting process.  Ultimately, a Phase 1 report not completed properly can lead to significant cost and time delays on projects as they move forward through the risk assessment process.

It is also a part of the job our consultants really enjoy doing, as it gets them out of the office and onto site.

We have completed site visits in recent weeks in rural Northumberland in the villages of Lucker and Amble, North Tyneside, Darlington, Ellesmere Port, Weardale and Blackburn.  Some photos from the visits are posted below.
