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 ...

Study on Non-Point Source Pollution in the Agricultural Watershed

Advanced Materials Research, 2013
This paper gives a review on the study of related factors of non-point source pollution (NPS) in water cycle. Hydrological process features, underlying surface conditions, human activities are sorted to introduce the recent research on NPS progress. Several major factors are divided in each item with developing process.

[A study on non-point source pollution models].

Huan jing ke xue= Huanjing kexue, 2002
With the effective control of industrial wastewater, pollution of non-point sources has become increasingly important in China. The understanding of non-point source pollution processes, mostly through mathematical models, is thus a prior knowledge to its effective control.

Collective liability in non-point source pollution

2011
Non point source pollution is characterized by the fact that individual emissions are not observable at a reasonable cost. This constitutes a moral hazard problem. Furthermore, we explicitly consider adverse selection, a second type of asymmetric information that arises because of the difficulty to differentiate the polluters with respect to their type

[A review on non-point source pollution models].

Ying yong sheng tai xue bao = The journal of applied ecology, 2008
With the effective control of point source pollution, the non-point source pollution (NPSP) of water environment has been paid more and more attention, and NPSP models are thriving with the development of 3S technology. This paper made a brief introduction about the classification and evolution of NPSP models.

How to regulate non point source pollution ?

2008
Les pollutions diffuses sont des pollutions ne pouvant être attribuées à un émetteur bien défini. Elles sont en conséquence difficiles à maitriser, et appellent des actions règlementaires mais aussi la conception d'outils collectifs innovants aidant à un changement de mentalité.

Agriculture Non-Point Source Pollution Control [PDF]

The Chesapeake Bay is the largest and historically most productive estuary in the United States. It is approximately 200 miles long and 35 mile wide at it broadest point. The Bay's watershed includes parts of six states (Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia, and the entire District of Columbia.
