When the snows melted in the lofty White Mountains in New Hampshire, hundreds of swollen streams flooded the Pawtomack River. Within a two-day period, its level rose several feet and its lazy seaward course became a torrent. Passing the town of Shaftesbury, the clear water raged against the old granite quays of the deserted mill building, spraying mist and miniature rainbows into the crystal air.
As the weather grew warmer green shoots thrust up through the ground along the river, growing in areas previously too toxic for them to survive. Even in the shadow of Recycle, Ltd., tadpoles appeared for the first time in years to chase the skittish water spiders, and rainbow trout migrated south through the formerly poisoned waters.
As the nights became shorter and hot summer approached, a single drop of benzene appeared at the juncture of an off-load pipe in one of the new chemical holding tanks. No one supervising the installations had fully understood the insidious propensities of benzene, and from the moment the first molecules had flowed into the new system, they began dissolving the rubber gaskets used to seal the line.
It had taken about two months for the toxic fluid to eat through the rubber and drip onto the granite blocks beneath the chemical storage tanks, but after the first, the drops came in an increasing tempo. The poisonous molecules followed the path of least resistance, working their way down into the mortarless masonry, then seeping laterally until they entered the river. The only evidence of their presence was a slightly aromatic, almost sweet smell.
The first to die were the frogs, then the fish. When the river fell, as the summer sun grew stronger, the concentration of the poison soared.
