Onondaga Lake

"Nine sites line the shore of Onondaga Lake, around which the present-day city of , has grown. Thanks to more than a century of industrial development, the lake known as one of North America's most sacred sites is now known as one of the most polluted lakes in the United States. Drawn by abundant resources and the coming of the , the captains of industry brought their innovations to Onondaga territory. Early journals record that smokestacks made the air "a choking miasma." The manufacturers were happy to have Onondaga Lake so close at hand, to use as a dumping ground. Millions of tons of were slurried onto the lake bottom. The growing city followed suit, adding sewage to the suffering of the waters. It is as if the newcomers to Onondaga Lake had declared war, not on each other, but with the land."

"From across the water, the western shore stands out in sharp relief. Bright white bluffs gleam in the summer sun like the White Cliffs of Dover. But when you approach by water, you’ll see that the cliffs are not rock at all, but sheer walls of Solvay waste. While your boat bobs on the waves, you can see erosion gullies in the wall, the weather conspiring to mix the waste into the lake: summer sun dries out the pasty surface until it blows, and subzero winter temperatures fracture it off in plates that fall to the water. A beach beckons around the point but there are no swimmers, no docks. This bright white expanse is a flat plain of waste that slumped into the water when a retaining wall collapsed many years ago. A white pavement of settled waste extends far out from shore, barely under water. The smooth shelf is punctuated by cobble-sized rocks, ghostly beneath the water, unlike any rock you know. These are s, accretions of , that pepper the lake bottom. Oncolites—tumorous rocks."

"The waste beds continue to leach tons of salt into the lake every year. Before the Allied Chemical Company, successor to Solvay Process, ceased operation, the salinity of Onondaga Lake was ten times the salinity of the headwaters of Nine Mile Creek. The salt, the oncolites, and the waste impede the growth of rooted aquatic plants. Lakes rely on their submerged plants to generate oxygen by photosynthesis. Without plants, the depths of Onondaga Lake are oxygen-poor, and without swaying beds of vegetation, fish, frogs, insects, herons—the whole food chain—are left without habitat. While rooted water plants have a hard time, floating algae flourish in Onondaga Lake. For decades high quantities of nitrogen and phosphorous from municipal sewage fertilized the lake and fueled their growth. Algae blooms cover the surface of the water, then die and sink to the bottom. Their decay depletes what little oxygen is in the water and the lake begins to smell of the dead fish that wash up on shore on hot summer days."

"The fish that survive, you may not eat. Fishing was banned in 1970 due to high concentrations of mercury. It is estimated that one hundred and sixty-five thousand pounds of mercury were discharged into Onondaga Lake between 1946 and 1970. Allied Chemical used the mercury cell process to produce industrial chlorine from the native salt brines. The mercury waste, which we know to be extremely toxic, was handled freely on its way to disposal in the lake. Local people recall that a kid could make good pocket money on "reclaimed" mercury. One old-timer told me that you could go out to the waste beds with a kitchen spoon and pick up the small glistening spheres of mercury that lay on the ground. A kid could fill an old canning jar with mercury and sell it back to the company for the price of a movie ticket. Inputs of mercury were sharply curtailed in the 1970s, but the mercury remains trapped in the sediments where, when methylated, it can circulate through the aquatic food chain. It is estimated that seven million cubic yards of lake sediments are today contaminated with mercury."

"Swimming was banned in 1940. Beautiful Onondaga Lake. People spoke of it with pride. Now they barely speak of it at all, as if it were a family member whose demise was so shameful that the name never comes up."
