 Nations on the shores of the lake. These warring nations accepted the Great Peacemaker's message of peace, laid down their weapons, and formed the Haudenosaunee Confederacy. Since then, the lake has become a sacred place.

The Onondaga Nation's "Vision for a Clean Onondaga Lake" states that the waters, plants, fish, shore birds, and animals of the lake are an intrinsic part of the people's existence. Onondagans view the restoration of the lake as a personal responsibility and are working towards efforts to make sure that the lake is clean enough to drink water, eat the fish, and swim in.

Early European Settlement

European knowledge of the salt springs occurred in 1654 when the Onondagas revealed their presence to French explorers. Jesuit missionaries visiting the Syracuse region at the same time period were the first to report on salty brine

 services departed from the pier and transported tourists to other resorts around the lake. The lake initially supported a cold-water fishery, but due to industrialization the cold-water fishery was lost by 1890.

Industry

The systematic production of salt began in 1797, when the New York State Legislature designated a one-mile-wide strip of land around the northern half of the lake as the Onondaga Salt Springs Reservation. Between 1797 and 1917, the Onondaga Salt Springs Reservation produced more than 11.5 million tons of finished salt].

Salt brine and limestone were the key raw materials for the production of soda ash. The abundance of salt brine and limestone in Onondaga Lake's watershed area attributed greatly for the industrialization along the lake's shoreline. Beginning in 1838, New York State authorized the drilling of deep wells at several locations around the lake. The wells intended to locate the source of the brine, however, no source was located.
The Solvay Process company, incorporated in 1881, began drilling deep test holes in the area south of Syracuse in 1883. The company's main product was soda ash whch was used to make glass, chemicals, detergent, and paper. Eventually Solvay encountered halite deposits at a depth of 1,216 feet below land surface in the southern end of Tully Valley. From 1890 to 1986 more than 120 wells were drilled into four halite beds on the east and west flanks of the valley]. Soda ash production began in 1884. The company was producing about 20 tons of soda ash per day and most of the waste material was dumped directly into Onondaga Lake. Eventually wastebeds were built along the southwest perimeter of the lake to contain the by-products of soda ash production. In 1907, the New York State Attorney General threatened the Solvay Process Company with legal action over the direct discharge of Solvay waste material into the lake.

In 1920, the Solvay Process Company merged with four other chemical companies and formed Allied Chemical and Dye Corporation. Allied Chemical and Dye Corporation began the production of chlorine by mercury cell in 1950. Mercury was dumped directly into Onondaga Lake. Allied Chemical and Dye Corporation became Allied Chemical Corporation in 1958. The continual practice of dumping mercury into the lake led to a fishing ban in 1970 due to mercury contamination of the fish. Allied Chemical was sued by the US Attorney General in order to halt the dumping of mercury into the lake. It is estimated that Allied Chemical was dumping approximately 25 pounds of mercury into Onondaga Lake per day. In 1981 Allied Chemical Corporation become Allied Corporation and again changed its name to Allied-Signal, Inc. in 1985 when it merged with the Signal companies. The company announced that it will close its operations in Syracuse and in 1986 began dismantling its facility.

In 1989, New York State filed a lawsuit against Allied-Signal, Inc. for its responsibility in the contamination of Onondaga Lake. New York State and Allied-Signnal, Inc. signed an interim Consent Decree detailing the elements of a Remedial Investigation and Feasibility Study of the lake. In compliance with the Consent Decree, the study was conducted by Allied-Signal, Inc. which became Honeywell, Inc. in 1999.

Non-salt-producing companies also established themselves along Onondaga Creek

 valley from the mid-19th century to the early 20th century. Many of these companies drilled wells into the underlying sand to obtain water for cooling purposes for the protection of dairy products and beer, storage of perishable goods, and temperature regulation in office and storage buildings. Once used, the water was disposed of in nearby streams that drained to Onondaga Lake. This practice increased the salinity of the surface-water system].

Sewage Pollution

One major source of pollution for Onondaga Lake is sewage wastewater. For years, Syracuse dumped human waste into the lake with little or no treatment. Before European settlement, the lake was oligo-mesothropic, meaning that it contained low levels of aquatic plant blooms. However, the high levels of ammonia

 due to the sewage wastewater have directly affected the lake and have led to excessive algae growth in the lake. The algae use large quantities of oxygen causing eutrophic and low-oxygen conditions. The low oxygen levels lead to the choking out of fish and plants, especially in the deeper areas of the lake.

Another issue contributing to sewage pollution is combined sewer overflow (CSO). In some areas of Syracuse there are sewers that carry both sanitary sewage and stormwater. During dry weather these sewers carry all the sanitary sewage to Metro for treatment, however, during times of heavy rain or melting snow the amount of water is greater than the capacity of the sewers and they overflow and discharge a combination of runoff and sanitary sewage into Onondaga Creek

 which flows north into the lake. Sediment loading is a problem because it degrades water quality, decreases water clarity, and reduces habitat for aquatic insects, fish spawning, and plants

Sewage Pollution Cleanup

The first steps taken to control sewage pollution occurred in 1907 with the creation of the Syracuse Interceptor Sewage Board. It served to address sewage-related problems in Onondaga Creek and Harbor Brook. In 1960, Onondaga County established a sewer district and built the Metropolitan Sewage Treatment Plant, Metro, on the south shore of the lake.

In 1988, Atlantic States Legal Foundation (ASLF), a Syracuse-based organization providing legal and technical assistance to citizens and organizations dealing with environmental problems, filed a lawsuit against Onondaga County alleging that Metro and the combined sewer overflow (CSO) discharges were violating federal water pollution standards established under the Clean Water Act of 1972. The state of New York joined as a plaintiff with allegations that Onondaga County had also violated the New York State Environmental Conservation Law.

In 1990, the U.S. Congress created the Onondaga Lake Management Conference (Public Law 101-596, section 401) and ordered it to develop a comprehensive revitalization, conservation, and management plan for Onondaga Lake that recommends priority corrective actions and compliance schedules for the cleanup of Onondaga Lake. The Onondaga Lake Management Conference also called for the coordination of implementing the plan. The largest responsibility of the Onondaga Lake Management Conference was the completion of the Onondaga Lake Management Plan.

In 1997, New York State and ASLF reached an agreement, the Onondaga Lake Amended Consent Judgment (ACJ) on municipal wastewater collection and treatment improvements. The ACJ also called for a schedule to attain compliance with the Clean Water Act. The ACJ is a multi-year program designed to improve the water quality of Onondaga Lake while achieving full compliance with state and federal water quality regulations by December 1, 2012. ACJ projects are divided into three main categories: wastewater treatment, collection system, and lake and tributary monitoring. In January 1998, a federal judge approved the ACJ and on September 1999, the Onondaga Lake Management Conference approved and endorsed the Amended Consent Judgment (ACJ). It incorporated the ACJ into its 1993 Onondaga Lake Management Plan entitled, A Plan of Action.

The final stage for ammonia discharge improvements occurred in 2004. The Biological Aerated Filter (BAF) system allows for year-round nitrification of wastewater. In 2004, Metros annual ammonia discharge was reduced to 152 metric tons and by 2005 the annual discharge fell to 21 metric tons. The ACJ also lead to the creation of an Ambient Monitoring Program (AMP) to track the effectiveness of the improvements made to the wastewater collection and treatment infrastructure. The AMP is designed to identify sources of materials to the lake, evaluate in-lake water quality conditions, and examine the interactions between Onondaga Lake and Seneca River. Since 2007, Onondaga Lake has been in full compliance with the ambient water quality standards for ammonia. It was officially de-listed for that particular parameter in the State’s 2008 list of impaired bodies of water.

The ACJ was not only successful in reducing ammonia discharges. Between 1993 and 2006, the phosphorus discharges from Metro were decreased by 86%. In regards to contamination via CSOs, the ACJ requires that by 2018 the county eliminate or capture for treatment 95% of the CSO volume generated during heavy rain and snow melt.

Chemical Pollution Cleanup

The State of New York filed a lawsuit against Allied-Signal, Inc. in 1989. The lawsuit sought to compel the company to clean up the hazardous wastes that it and its predecessors had dumped into and around the lake. In 2005, New York State Department of Environmental Conservation (NYSDEC) and the Environmental Protection Agency (EPA) issued a Record of Decision that outlined the remediation plans of Onondaga Lake. The Federal Court approved a Consent Decree in 2007, obliging Honeywell International, Inc. to implement the NYSDEC/EPA cleanup plan for the contaminated sediments in the bottom of the lake. Honeywell signed the Consent Decree that same year and sets out to perform the Remedial Design and Remedial Action for the Onondaga Lake Bottom Site.

The cleanup plan calls for the dredging of up to 2.65 million cubic yards of contaminated sediments to a depth that will allow for a cap to be built without losing any lake surface area. The sediments will be hydraulically dredged from the bottom of the lake and piped to a sediment consolidation area in Camillus, New York. Dredging is expected to begin in 2012. The cap that the plan calls for would cover 580 acres of lake-bottom. The plan also calls for the installation of a barrier wall made of steel on the southwest corner of the lake. In 2008, Honeywell began second phase construction on this barrier wall. The estimated cost of the cleanup plan is $451 million; an estimated $414 million in order to construct the remedy followed by an annual maintenance cost of $3 million.

Onondaga Nation is not content with the Remedial Action plan for the Onondaga Lake Bottom Site. Their website states that the dredging plan will not include the additional18 million cubic yards that the NYSDEC found to be contaminated. Isolation caps are not viewed as a permanent reliable form of containment. The caps will not cover the entirety of the lake-bottom and they will eventually fail. Onondaga Nation states that the New York State goals do not include making the lake swimmable or fishable which is what the Clean Water Act calls for. The total estimated plan, according to Onondaga Nation, of a thorough cleanup would cost $2.16 billion.

Sedimentation Control

Since 1992, the Onondaga Lake Partnership has supported the efforts of the United States Geological Survey (USGS) in the following remedial activities: the diversion of surface water away from the mudboils, the installation of a dam on the stream that flows from the mudboils area, and the drilling of wells to reduce the pressure around the mudboils (21). The installation of several depressurization wells has led to to dramatic decreases in sediment loading; an average of 30 tons per day was reduced to 1 ton per day.

Land rights action

The lake is also subject of a land right action filed on March 11, 2005 by the Onondaga Nation. The land rights action stipulations that pertain directly to the lake include the protection and conservation of the natural resources within and affecting the Nation's land and the security of Onondaga rights to hunt, fish, and gather for subsistence and cultural needs. According to Sid Hill, the Onondaga's Tadodaho, the Onondaga people want the water, land, and air returned to the condition it was in when it was illegally lost in the 18th and 19th centuries. Hill sees the current state of Onondaga Lake as evidence of New York State and federal authorities' inability to care for the land. The land rights action was dismissed by a federal judge on September 22, 2010.
