Abstract Of the approximately 4000 waste disposal sites in Ontario, more than 230 are located within 5 km of the shoreline of the lower Great Lakes. Sixty sites are within 1 km of the shore. Unlike the more resistant bedrock shores of the Upper Great Lakes, the shoreline between Midland (Georgian Bay) and Kingston (Lake Ontario) is composed primarily of unlithified glacial deposits, and thus is prone to significant erosion. This report presents an examination of the potential for contamination of nearshore lake waters either directly through shoreline recession at the waste site, or indirectly through the transport to the lake of leachates from the nearby sites via groundwater discharges. Recession-related hazards were identified at three sites (two on Lake Ontario and one on Lake Erie). Groundwater contamination hazards were harder to identify due to insufficient subsurface and hydrogeological information. However, 31 sites, less than 0.2 km from the shore, were identified as potentially hazardous; 19 of these were located in the northern Lake Ontario shore zone.

Lateral Variations

We present an approach to the use of electomagnetic geophysical methods for delineating groundwater contamination, and test the concepts at three waste disposal sites. The approach includes a technique for modelling a site's response to a variety of instruments, and a device-independent method of contouring the data. The modelling attempts to account for the noise inherent in the measurement process, particularly the effects of lateral variations in stratigraphy. These concepts are evaluated by comparing the geophysical response to groundwater conductivities measured in sampling wells. We conclude that geophysics offers a cost-effective supplement to drilling, and that it is best used in a reconnaissance mode to map the general distribution of contamination prior to a detailed sampling program. The correlation between the observed and predicted geophysical response as a function of groundwater conductivity is as good as can be expected given the uncertainties in the process. The methodology proposed is simple to use and practical. Key words: groundwater, contamination, geophysics, electromagnetic, mapping, modelling.

A description of how three communities in Ibadan, Nigeria, tackled the problem of waste disposal and drainage improvement. A community diagnosis used numerous research methodologies, including survey, participant and non-participant observation, group discussions, and home visits to establish a baseline and design a community intervention and evaluation. The three community approaches are compared, the differences analyzed, and the strengths of one intervention emphasized.
