The Economics of Non-Point-Source Pollution [PDF]

Annual Review of Resource Economics, 2011
Non-point-source (NPS) pollution refers to a form of pollution in which neither the source nor the size of specific emissions can be observed or identified with sufficient accuracy. In NPS pollution the ambient concentration of pollutants associated with the individually unobserved emissions is typically observed.

Challenges in non-point source pollution - sampling and testing

5th Brunei International Conference on Engineering and Technology (BICET 2014), 2014
Point pollution sources are usually noticeable, confined and the pollution loads are relatively easy to estimate. Therefore, the treatment technologies can be easily applied to abate pollution from the point sources (PS). On the contrary, non-pointsource (NPS)pollution is generated due to precipitation process, and it is usually difficult to estimate ...

Non point source pollution

IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002
Non Point Source (NPS) pollution is a major contributor to the degradation of surface water quality. NPS pollution is caused by water movement over and through the surface of the land. The runoff picks up and transports natural and man-made pollutants.

Pollution: Non-Point Source

2016
The biosphere is a life-supporting system to the living organisms. The detection of hazardous compounds in Antarctica, where these compounds were never used or no man has ever lived before, indicates how serious is the problem of long-range atmospheric transport and deposition of non-point-source pollution.

An Efficient Algorithm for Non-point Source Pollution Management Problems

Journal of the Operational Research Society, 1994
Summary: A dynamic programming (DP) algorithm is proposed for a class of non-point source pollution control problems. The formulation deals with the selection of a spatial distribution of management practices in such a way as to meet a control agency's sediment pollution target. The inherently combinatorial nature of these problems -- stemming from the

Quantification and Source Identification of Uncertainty in Non-Point Source Pollution Loads

Journal of Hydrology
Quantifying uncertainty associated with non-point source (NPS) pollution loads and identifying its key sources are crucial for enhancing the accuracy of NPS load simulation and prediction, understanding NPS variability under climate change and extreme weather events, and enabling effective watershed pollution control.
