Abstract

In a region of the world where water resources are scarce and extensively utilised, there is a significant risk of exceeding the assimilative capacity of natural water courses. It is thus understood that the standards for pollution control barriers may vary between countries across the planet. South Africa has adopted norms and standards for waste containment which employ composite liners within contaminant containment barrier systems similar to the more than 100 regulatory standards worldwide.


While technical literature gives valuable guidance on service life prediction and performance, including under elevated temperature conditions, it is necessary to consider the extent of relevance to local conditions. The nature of rainfall events and ambient temperature conditions can be expected to lead to higher liner temperatures than in the colder regions of the world, and consideration of the thermal conductivity influences within barrier systems may require one or more of a range of mitigation measures to be incorporated in the design and operation for effective pollution control and water resource protection.
