As a hydrogeologist and environmental consultant, I’ve studied the perilous relationship between groundwater and various forms of contamination. This series includes an image of a town dump and of a gasoline station in small New England towns. While the scene above ground may seem familiar, the earth below shows the mark we make on the earth in the name of progress. In researching and documenting these sites, I’ve come to understand how vulnerable groundwater is to different kinds of land use.
