The South Lake Union neighborhood is located next to
downtown Seattle and bordered on the north by Lake Union.
This area has a long history of industrial and commercial
activities which caused contamination of the soil and
groundwater. Currently, this area is undergoing extensive
redevelopment as new buildings are constructed for
commercial and residential use. Ecology is working with
property owners to clean up contamination at these sites to
reduce impacts to human health and the environment.
