  1. Onondaga Lake Recovery By Cory Gionet

  2. History HISTORY

  3. NATURAL BEAUTY Location of many homes and beach resorts. Great lake for fishing.

  4. POLLUTION ERA • As Syracuse became more industrialized in the late 19th century, factories continuously dumped sewage and waste into the lake.

  5. POLLUTANTS

  6. EFFECTS

  7. THE RESULT

  8. RESTORATION

  9. 1970s • Clean Water Act in 1972 • required that all of New York state's fresh waters should be suitable • for swimming and the propagation of fish and other aquatic life • The county and the state banned the use of phosphorus in laundry detergents • A lawsuit was filed against Allied Chemical Corporation to stop • mercury dumping • An upgrade occurred at the Syracuse solid waste treatment plant (METRO) • to improve sewage treatment • Allied Chemical Corporation's chlorinated benzene and Willis Avenue • chlor-alkali plants were closed • Studies were conducted on the impacts of industrial wastes, combined • sewer overflows and treated sewage

  10. 1980s • Use of best management practices for sewer interception which reduced combined sewer overflow events by 90% • Filing of a complaint against the Onondaga County Department of Drainage and Sanitation by the New York State Department of Environmental Conservation, the New York State Attorney General and the Atlantic States Legal Foundation alleging violation of state discharge permit • Filing of a complaint by the New York State Department of Environmental Conservation and the New York State Attorney General against Allied-Signal Inc. alleging pollution violation and resource damage • Industrial pre-treatment program instituted by the County • Closure of Allied Corporation's soda ash facility • Catch and release fishing reinstatement • Closure of LCP-Hanlin's Bridge Street chlor-alkali plant.

  11. 1990s • Creation of a "Plan for Action" for the Lake written by the newly established Onondaga Lake Management Conference, a group consisting of representatives from local, state and federal governments • Signing of the Amended Consent Judgment by Onondaga County, which requires the County to upgrade existing sewage treatment system and construct facilities and transport system to comply with permit discharge limits and water quality standards • Modifications to pump station at Liverpool and Ley Creek to eliminate raw sewage overflows • Commencement of aquatic habitat restoration projects in Onondaga Lake • Completion of mudboil remediation projects to reduce flow of sedimentation to Onondaga Creek

  12. PROGRESS • Several improvements made to Metropolitan Syracuse Wastewater Treatment Plant • Insulation of the roofs of digesters #1 and #3 • Replacement of three waste-gas burners • Ventilation improvements in the digester control house • Installation of new instrumentation • Replacement of a sluice gate • Installation of new piping and overflow weirs in the diversion structure.

  13. CONT’D • Along with the updates made in the 1970s on the waste water plant, Biological Aerated Filters were installed into plant in 2004 and have accounted for a massive decrease in ammonia in the lake. Average ammonia-N concentrations in Metro Outfall 001, seasonal basis, 1995-2006

  14. CONT’D • Through new facilities and high-rate flocculated settling, Onondaga Lake has seen dramatic decrease in its phosphorus levels. Average daily phosphorus discharge from Metro, 1990-2006

  15. GOALS • Restore and maintain the ecosystem of the lake • Allow swimming once again in the lake • Allow fishing propagation again • Allow secondary recreational activities All goals are to hopefully be reached by December 1, 2012 in accordance to the Clean Water Act and Environmental Law.
