Sludge runoff at the Lowry Landfill, about 1978. The fan is where a liquid waste ran out across the ground and dried in place; the sunflowers came afterwards.

Shows: The path a liquid waste took over the surface, still legible after it dried.

What this does not let you conclude: Whether it reached groundwater, and what it was. Neither is in the frame nor in the caption the Survey wrote for it. The library's own "circa 1978". Its companion frame at this site is dated 1978 flat.
