Nonpoint

Runoff that occurs on surfaces before reaching a channel is also called a nonpoint source. ❋ Unknown (2009)

If a nonpoint source contains man-made contaminants, the runoff is called nonpoint source pollution. ❋ Unknown (2009)

The group supports cost-effective measures to reduce the load of phosphorus coming from runoff, also known as nonpoint pollution. ❋ JSOnline.com (2010)

Engel said he used a computer model to estimate the impact of so-called nonpoint phosphorus on the watershed under a variety of scenarios.

For "nonpoint" runoff, voluntary programs, including cost-sharing with landowners are the key tool. ❋ Unknown (2008)

• $97 million to stop "nonpoint" pollution, such as farm fertilizer and oil runoff, that closes beaches and leads to fish kills. ❋ Unknown (2009)

The current rules are biased against potentially more cost effective pollution control through "green infrastructure" that reduces nonpoint sources of pollution. ❋ Steven Cohen (2011)

For example, EPA recognizes that nonpoint or diffuse sources of water pollution are our largest remaining water problem and the fundamental reason that 40 percent of our rivers, lakes, and estuaries are not fishable or swimmable. ❋ Steven Cohen (2011)

As a lower cost alternative, the county proposed an imaginative series of ecosystem restorations to reduce nonpoint discharges to the same body of water. ❋ Steven Cohen (2011)

And the EPA sets standards for impervious surface through nonpoint pollution runoff standards. ❋ Unknown (2009)

• EPA should improve enforcement of drinking water systems and nonpoint source pollution (e.g., runoff from farms). ❋ Unknown (2010)

At EPA he has led in the design and development of national and regional maps of stream nutrient concentrations attributable to nonpoint sources, total alkalinity of surface waters, total phosphorus regions for lakes, and ecoregions. ❋ Unknown (2010)

This type of nonpoint source pollution can result in acid rain that can slow forest growth and contaminate soil. ❋ Unknown (2009)

Although the pollutants may have originated from a point source of air pollution such as a factory, the long-range transport and multiple sources of the pollutant make it a nonpoint source of pollution. ❋ Unknown (2009)

Broad support for this policy change was based on the notion that traditional approaches to pollution control had achieved progress, but may in the future be supplemented with new approaches that might better address cross-media pollution transfers, the need for cost-effective alternatives, and methods of controlling pollution from dispersed or nonpoint sources of pollution. ❋ Unknown (2009)

Ecoregions are directly applicable to the immediate needs of state agencies, including the development of biological criteria and water quality standards and the establishment of management goals for nonpoint-source pollution. ❋ Unknown (2009)
