Channeling Change - Stream Restoration on OSU Marion Campus |
 Grave Creek
Grave Creek, as the ditch is officially known, is the site of a proposed restoration project undertaken by Klips and a team of environmentally minded faculty on both the Marion and main campuses. Covering a swath of creek not quite a mile in length, the proposal calls for creating a new, more naturally curving channel that will be able to accommodate flood patterns and sustain an educationally valuable habitat. That habitat includes a roughly 1.5-acre wetland that will improve the water quality of Grave Creek itself.
“Wetlands are like nature’s kidneys: They’re actually able to filter water,” explained Bill Mitsch, director of the Wilma H. Schiermeier Olentangy River Wetland Research Park in Columbus. Water quality testing at the Marion site indicates that runoff from agricultural fields has made Grave Creek high in phosphorous and nitrates, chemicals that could be reduced by a wetlands. |

Ohio EPA Finalizes Total Maximum Daily Load Report for Olentangy River Watershed |
|
The Ohio Environmental Protection Agency released the final version of the 'Total Maximum Daily Loads for the Olentangy River Watershed' report on August 24, 2007. To view a copy of the report, please visit http://chagrin.epa.ohio.gov/dsw/tmdl/OlentangyTMDL_final_aug07.pdf The Ohio EPA's Total Maximum Daily Load (TMDL) program, established under Section 303(d) of the Clean Water Act, focuses on identifying and restoring polluted rivers, streams, lakes and other surface waterbodies. A TMDL is a written, quantitative assessment of water quality problems in a waterbody and contributing sources of pollution. It specifies the amount a pollutant needs to be reduced to meet water quality standards, allocates pollutant load reductions, and provides the basis for taking actions needed to restore a waterbody. |

Sources of Nonpoint Source Polution |
Related to water resources, nonpoint source pollution is the introduction of impurities into a surface-water or an aquifer, usually through a non-direct route and from sources that are "diffuse" in nature, meaning there is not a direct discharge pipe. Discharges from nonpoint sources are usually intermittent, associated with a rainfall or snowmelt event, and occur less frequently and for shorter periods of time than do point source discharges. Nonpoint sources of pollution are often difficult to identify, isolate and control.
"Nonpoint Source" is commonly abbreviated as "NPS." Examples of NPS pollution include: automobile emissions, road dirt and grit, and runoff from parking lots; runoff and leachate from agricultural fields, barnyards, feedlots, lawns, home gardens and failing septic systems; and runoff and leachate from construction, mining and logging operations. Most NPS pollutants fall into six major categories: sediment, nutrients, acid and salts, heavy metals, toxic chemicals and pathogens, according to the U.S. Department of Agriculture (USDA), and other state and federal agencies.
