Title: Pliocene Lignite Bed
Description: Seam or bed of Pliocene lignite from a mine in the Balkan endemic nephropathy (BEN) area of Romania. Rainwater falling onto the surface penetrates into the ground, becoming ground water, and leaches toxic organic substances from this coal. The ground water continues to BEN villages in the valleys below carrying toxic organic substances, feeding shallow wells and springs used by villagers as a primary drinking water supply.
