into an open pit which was part of the overall construction; Mann sued Harvey for damages; Harvey brought suit against defendants and Harvey's insurer to establish his right to be defended in the suit and to be indemnified for any judgment Mann might recover. After holding that the policy issued to Harvey covered the threatened liability to Mann the court assumed that Mann's injury was a consequence of some breach of duty owed to Mann on the part of Harvey, and said at page 448, "Most significantly of all, the claimed breach of duty on the indemnitee's part was not active, affirmative misconduct, but at most passive negligence--a failure to act in fulfillment of a duty of care which devolved upon the indemnitee as the owner or occupierTopics of water sciences and technology.
In the preceding series of contributions to ESPR typical examples from actual fields of water chemistry were presented on various topics: integrated water quality management, diagnosis of water bodies, therapy of aquatic systems, and fitness for aquatic systems. These contributions clearly showed the need and importance of more intensive research. In the principle committee III 'Basic Research' of the Water Chemical Society, various expert groups work on scientific backgrounds in these fields. Some relevant topics are selected in this outlook, mainly on interactions of solids with water, the role of environmental colloids, the development of modern biochemical methods for diagnosis, the impact of chemical speciation on bioavailability and water technology, and the development of advanced methods in water treatment technology. Innovative approaches to
