What Should You Know About Preliminary Site Investigation NSW?

If an individual is in the process of acquiring new land in NSW or developing a piece of land, there must be a need to know the past and present condition of that piece of land as it may be contaminated in the past or in the present. It can be said that conducting comprehensive site investigations may offer this perspective.

Site investigations come in two main forms: Preliminary Site Investigation NSW can be defined as site investigations that are carried out at an early stage of a project while detailed site investigations are those that are conducted after preliminary site investigations have been conducted. The initial investigation of a site or an initial site assessment or an PSI NSW is the first step in assessing a property for contamination.

It entails surveying through documents such as historical documents, aerial images, reports and other relevant documents to establish the previous uses of the land that would have led to pollution including, for instance, old stations, factories, storage facilities etc. A site visit is also made to observe any physical signs of pollution.

A Detailed Site Investigation NSW comprehensively assesses the concentrations of the contaminants in soil, water and vapors over a particular area by conducting numerous samples and analyzing them in the laboratory. It assists in establishing the nature and degree of contamination which is present to make necessary clean up if they are contaminated. DSIs entail a lot of work that can only be done by environmental consultants with adequate time to develop the strategies to be implemented.

In NSW the laws governing site contamination and remediation are provided under the Contaminated Land Management Act 1997. It is strongly recommended that all PSIs and DSIs are conducted by consultants accredited under the Environment Institute of Australia and New Zealand Certified Environmental Practitioner (Site Contamination) program to help ensure quality.
