The Ohio water resource region is one of 21 major geographic areas, or regions, in the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units. These geographic areas contain either the drainage area of a major river, or the combined drainage ...

Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The Ohio River at Cairo is 281,500 cu ft/s (7,960 m 3 /s); [1] and the Mississippi River at Thebes, Illinois, which is upstream of the confluence, is 208,200 cu ft/s (5,897 m 3 /s). [66] The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system.
This is a list of Superfund sites in Ohio designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law.The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

GIS in environmental contamination is the use of GIS software in mapping out the contaminants in soil and water using the spatial interpolation tools from GIS. [ 1 ] [ 2 ] [ 3 ] Spatial interpolation allows for more efficient approach to remediation and monitoring of soil and water contaminants.
Considered the most contaminated river basin in the country. [198] [199] The river's watershed drains approximately 67% of Costa Rica's untreated organic and industrial waste. [198] [199] Tijuana River: Baja California, Mexico California, United States: Called "one of the most polluted waterways in the country". [200]
The lake contains 20 billion US gallons (7.6 × 10 10 litres; 1.7 × 10 10 imperial gallons) of coal ash and smokestack scrubber waste. [2] The northern coast of the lake is only a few hundred meters from the Ohio River, which is the drinking water source for more than three million people.
