This paper provides a means of appraising the potential effects of highways on surface water, groundwater resources, aquatic organisms and aquatic ecosystems, giving examples of procedures to identify and assess potential impacts and minimise damage. To assess the effect of a new highway, each of the impact categories should be initially examined on a broad regional scale to identify likely interaction. The information can be presented in a matrix relating characteristics of the proposed development (and alternative) to the characteristics of the site. Potential environmental impacts identified in the matrix can then be assessed using a "screening test" to isolate those aspects upon which there may be an important impact. Subsequent assessment may then be focused on those aspects to decide if alternative plans should be re-studied in detail to minimise potential adverse impacts. The detailed studies should then be undertaken by experts to produce a baseline summary table. The potential impact of the project activity on each environmental element should also be assessed. The most effective method of minimising impacts is to avoid areass critical to normal functioning of aquatic ecosystems. However, as this is not always possible, the author suggests planning measures for a variety of problems. (TRRL) (TRRL)
