thousands of sites throughout the region have not been properly investigated re
environmental standards, and until the 1980s environmental law was lacking--and
it was common to discharge waste directly to the environment in the direct
vicinity of industrial facilities. In
short, legacy issues both exist and are often covered up--which means the

Although obligatory testing is not always the norm, the discovery of contaminants will oblige costly cleanup operations or worse.
Site audits are typically approached in the following fashion:
- Phase one--a review of existing knowledge and information through a local investigation and interviews with informed people to discover the site history (processes, technologies, location of facilities, chemicals used, pollutants migration pathways and impact mechanisms). Phase one will identify potential hazards and decide on further action.
- Phase two--this is analytical confirmation of pollution levels, which is conducted through screening methods which are covering a wide range of parameters. Testing covers approximately 500 compounds in soil and water, but testing needs to be tailored for you site or you are potentially wasting time and money
- Phase three--this is the delineation of the spatial extent of pollution and identification of remediation technologies. This may also involve supervision and monitoring of remediation work. This phase typically requires extensive drilling and sampling to recognize spatial distribution of pollutants. It also involves knowledge of risk assessment and modeling of pollutant transfer in soil and water, as well as the impact on health and the ecosystem.
