Concentration Of Selected Priority Organic Contaminants In Fish Maintained On Formulated Diets In Lake Ontario Waters, Joseph Buttner, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

Fish were grown in Lake Ontario water under conditions simulating commercial aquaculture and then analyzed for 10 priority organic contaminants. Black bullheads (Ameiurus meias) were grown in cages placed in a bay of Lake Ontario. Rainbow trout (Oncorhynchus mykiss) were grown in terrestrial raceways served with Lake Ontario water. Yearlings were reared on a commercial ration in these systems, which partially isolated them from the contaminant-laden food web and bottom sediments, to an average weight of 93 g for black bullheads (range, 31-220 g) and 213 g (29-558 g) for rainbow trout. Concentrations of contaminants in skinless fillets of both …

Uptake And Retention Of Mirex By Fish Maintained On Formulated And Natural Diets In Lake Ontario Waters, Joseph Makarewicz, Joseph Buttner, Theodore Lewis

Joseph C Makarewicz

Fish with no detectable levels of the contaminant mirex were grown in Lake Ontario waters under conditions simulating commercial aquaculture. Benthic black bullheads (Ameiurus me/as) were grown in cages placed in a bay of the lake. Pelagic rainbow trout (Oncorhynchus mykiss) were grown in terrestrial raceways served with Lake Ontario waters. Contaminant-free fingerlings were reared to a large size on a commercial ration in these systems, which partially isolated them from the contaminant-laden food web and bottom sediments. Black bullheads fed a mirex-spiked, commercially prepared food had mirex concentrations that exceeded the U.S. Food and Drug Administration (FDA) action level …

An assessment of the Canaseraga Creek watershed was undertaken to determine the nutrient and sediment contribution to the Lower Middle Main Stem of the Genesee River and to determine sources of nutrient and sediment loss geospatially within the Canaseraga Creek watershed. To accomplish this task, a multifaceted, integrated approach was taken by a combination of monitoring, segment analysis, and modeling (Soil and Water Assessment Tool). Thus, the river was monitored for discharge, water chemistry, and loss of nutrients and soil for an entire year (3 August 2010 to 14 February 2012) at the USGS stations at Shaker’s Crossing and Dansville, …


Niagara River Niagara County, New York, Joseph Makarewicz, Matthew Nowak May 2013

Niagara River Niagara County, New York, Joseph Makarewicz, Matthew Nowak

Joseph C Makarewicz

The Niagara River carries water from Lake Erie to Lake Ontario and is the major source of Lake Ontario’s water volume. Famous for the immense Niagara Falls, the 36-mile river is used by over 1 million people in the United States and Canada for functions including drinking water, recreation, and hydropower (Niagara Parks 2009). The Niagara River drains the entire upper Great Lake system into the final lake, Lake Ontario, and due to this huge volume of water has a large potential to change Lake Ontario’s water quality. Nuisance algae, bacterial abundance, and algal mat development along the southern shoreline …

Port Bay Wayne County, New York, Joseph Makarewicz, Matthew Nowak

Joseph C Makarewicz

Located midway between Rochester and Oswego, New York, Port Bay is one of southern Lake Ontario’s larger but relatively shallow (<25 feet) embayments. The perimeter of the bay is primarily residential, but portions of the shoreline and watershed are part of the Lake Shores Marshes Wildlife Area. Wolcott Creek is the major tributary of Port Bay and drains ~27 mi2 of land that is mostly in agriculture. The bay receives treated effluent from the Village of Wolcott Sewage Treatment Plant. Port Bay suffers from cultural eutrophication and is on the New York State 303d list of Impaired Waters due to an overabundance of phosphorus. Benthic anoxia is a major effect of this eutrophication. Port Bay is impacted by nuisance algae, and harmful algal blooms have been observed (Makarewicz et al. 2009). This short report provides a synopsis of …


Irondequoit Bay Monroe County, New York, Joseph C. Makarewicz, Matthew J. Nowak May 2013

Irondequoit Bay Monroe County, New York, Joseph C. Makarewicz, Matthew J. Nowak

Joseph C Makarewicz

Irondequoit Bay is approximately 4.2 miles long and 0.6 miles wide and is separated from Lake Ontario by a small barrier beach. Irondequoit Bay had been historically considered hypereutrophic when several sewage plants discharged directly into the bay; however, aggressive restoration by Monroe County has improved the eutrophic state of the bay. Restoration efforts included sealing the bottom sediments with alum, reducing both point and non-point sources of phosphorus, and the pumping of air into the hypolimnion to reduce phosphorus movement from the sediments into the water. Currently no direct sewage plant discharge is received, and phosphorus levels are approaching …

Nutrient And Soil Losses From The Eighteenmile Creek Watershed, Joseph Makarewicz, Theodore Lewis, Daniel White, Mark Seider, Victor Digiacomo

Joseph C Makarewicz

Determination of sources and magnitude of soil and nutrient losses from a watershed is prerequisite to remedial action and essential to making cost-effective land management decisions as it reduces the likelihood of costly miscalculations based on the assumption of soil and nutrient sources and modeling rather than their actual identification. This process enhances the ability of concerned groups to obtain external funding for demonstration and remedial projects. In July 2003, the Niagara County Soil & Water Conservation District (NCSWCD), in conjunction with the Department of Environmental Sciences and Biology at SUNY Brockport, began a monitoring program for Eighteenmile Creek, located …

The Occurrence Of Cyanotoxins In The Nearshore And Coastal Embayments Of Lake Ontario, Joseph Makarewicz, Gregory Boyer, William Guenther, Mary Arnold, Theodore Lewis

Joseph C Makarewicz

Cyanotoxins are an emerging issue that Great Lakes’ scientists are conducting research on to determine occurrence, spatial and seasonal distribution, monitoring strategies and potential causes in Lake Ontario. Conditions necessary for blooms of Cyanobacteria exist along the shoreline of Lake Ontario. This is especially true in some embayments and rivers as levels of the nutrient phosphorus that stimulates the growth of Cyanobacteria is above New York State Department’s of Environmental Conservation guidelines. Monitoring in 2004 demonstrated that abundance of Cyanobacteria are indeed high in streams, embayments and the nearshore compared to offshore waters of southern Lake Ontario. Initial research suggests …

The shoreline of the Buffalo River is developed with heavy industry such as Republic Steel, Allied Chemical, Mobil Oil and numerous grain elevators. Similarly, on southeast shore o f the Outer Harbor, heavy industry such as Bethlehem Steel, Huron Cement and Lackawanna Steel is evident. On the eastern shore o f the Outer Harbor, freighters unload salt, taconite, coal, etc. into large storage piles for later use by the area industries. Large lake-going freighters and oilers routinely use the previously dredged channel existing along the entire length of the study area (Fig. 1) while servicing the industries located along the …


Eighteenmile Creek Remedial Action Plan Area Of Concern Planktonic Community Study, Joseph Makarewicz, Theodore Lewis May 2013

Eighteenmile Creek Remedial Action Plan Area Of Concern Planktonic Community Study, Joseph Makarewicz, Theodore Lewis

Joseph C Makarewicz

The preponderance of evidence suggests that the plankton community of Eighteenmile Creek is not impacted by contaminants. The summer zooplankton community of Eighteenmile Creek has a similar or higher species richness, a remarkably similar measure of dominance (i.e., evenness) and in July, a comparable abundance to the relatively pollution-free reference sites at Yanty, Buttonwood, and Salmon Creeks. Similarly in June, zooplankton abundance, species richness, and evenness for Eighteenmile Creek were between the values for the reference sites at Yanty Creek and Buttonwood and Salmon Creeks. Further support of this analogous comparison is provided by the phytoplankton data. Species richness, evenness, …
