Control site issues

Finally, As interacts with macrobiota either directly or via the food chain. As well as the issue of toxicity, there is the potential problem of As accumulation in animal flesh. Freshwater snails in the Waikato River, for example, were found to have 20 times the As content of snails in a control site (Golding et al., 1997). However, there has been little evidence that animals further up the food chain, such as trout, accumulate As from the Waikato River (Robinson et al., 1995).

Security issues involving access controls are typically line management responsibilities. However, it is not unheard of to have the SSHO in charge of site access or other security-related matters.

The nature of a project may warrant assigning a member of the site security staff to the project team. Key duties of the security officer may include the following ... 

Disposal of industrial effluents to controlled landfill sites is generally confined to slurries and sludge. The quantity and composition of the wastes acceptable for disposal is controlled by licenses issued by the waste disposal authority.

A number of contaminated sites have been used for illustration, though the extent to which bioremediation has received practical application is variable. For a number of reasons, emphasis is placed on basic microbiological issues that have emerged from controlled laboratory experiments ...
