Environmental Assessment

The foundation of any environmental or contaminated land project is the data base that is generated for a site. Relevant data for a contaminated site isn’t just about some sampling and test results of soil, vapour and water, it is about relevance, accuracy, precision and reliability. Projects can linger in confusion, doubt and rework if data needs are not well defined early on in a project. Depending on the project, data may be required of the site geology, hydrogeology, spatial and temporal variations, contaminant properties (density, viscosity, solubility, volatility to name a few) and phase distributions (liquid phase, solid phase or gaseous phase). Peraco staff bring decades of expertise in the understanding of the importance and relevance of different environmental information and how such information can be reliably obtained. Peraco works with clients to develop and define suitable assessment work scopes which can be implemented by others or Peraco can self-perform the investigations, depending on client specific needs. Typical investigation strategies include combinations of the following: 

 

Once the base data for a site is gathered and verified the assessment of impact and risk of the contamination can be evaluated. Peraco provides a wide range of services depending on site specific needs but may include:
