Nutrients And Sediment In The Western Lake Erie Basin

Sediment and nutrient runoff (nitrogen and phosphorus) from agricultural and urban land-use practices are of great concern in the Western Lake Erie Basin watersheds. Excessive nutrient inputs can lead to algal blooms that deplete the oxygen available to aquatic plants and animals. The blooms may result in cyanotoxins or cause taste and odor problems to public water supplies.

Stormwater Control Measures (SCM) Monitoring Near Cincinnati And Cleveland

Green infrastructure (GI) is a retrofit or as-built approach to managing stormwater as near its source as possible by minimizing impervious surfaces and promoting more natural infiltration and evapotranspiration than is typically associated with developed areas. There are a variety of GI stormwater control measures, including rain gardens, bioretention features, and pervious pavements. At the...

Natural Background Methane In Ohio Aquifers: Occurrence, Isotopic Characteristics, And Relation To Arsenic Concentrations

Arsenic is odorless and tasteless and can enter drinking-water supplies from natural deposits in rock and soil. In some parts of Ohio, arsenic concentrations in groundwater have exceeded the arsenic drinking-water standard of 10 parts per billion that the U.S. Environmental Protection Agency has set to protect consumers from the effects of long-term, chronic exposure to arsenic(U.S....

Using New Tools To Better Understand And Predict Harmful Cyanobacterial Algal blooms (HABs) At Ohio Lake Erie And Inland Beaches

In Ohio, local health officials and state agencies have identified the presence toxins associated with harmful algal blooms (HABs) caused by cyanobacteria during the summer and early fall seasons at recreational and water-supply lakes. The USGS, in cooperation with partner organizations, is monitoring recreational beaches and swimming areas in Ohio to better understand the link between...

Biodegradation Of Microcystins In Lake Erie Source Waters And Filters From Drinking-Water Plants

Harmful cyanobacterial “algal” blooms (cyanoHABs) and associated toxins, such as microcystin, are a major global water-quality issue.  In Lake Erie, researchers and local health officials have identified the presence of cyanobacterial blooms during the summer and early fall seasons. This is especially pronounced in the Lake Erie Western Basin, where the City of Toledo was forced to issue a do-...

Sediment Network In Ohio

Hellbranch Run is a second order stream tributary to Big Darby Creek. Big Darby Creek was designated a “National Scenic River” in 1994 by the U.S. Department of the Interior. Beginning in 1992, concern about the possible effects of urbanization on water quality in Hellbranch Run (and ultimately Big Darby Creek) prompted the USGS, in cooperation with the City of Columbus, Ohio, to begin...

Modeling Aquatic Species Distributions On The Basis Of Physical Habitat

Gap analysis is a coarse-scale assessment of aquatic biodiversity and conservation, the results of which can be used to guide biological field studies and monitoring programs. Potential species distribution models were developed for 130 fish, 70 bivalve, and 17 native crayfish species on the basis of a physical habitat-based classification of the perennial streams in Ohio.
