    Environmental pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source ?bookID= This book is designed to review present knowledge and experience regarding the assessment and control of nonpoint source pollution. The intention is to be practical and to be applicable in developed and developing countries. It is concerned primarily with nonpoint source pollution from agriculture, urban construction and forested areas, including the health of aquatic ecosystems and human use

    Agriculture activities are a leading cause of nonpoint source (NPS) pollution in the USA [].Nonpoint source pollution in Louisiana’s rural watersheds comes primarily from row crop agriculture and repetitive application of poultry manure on the same parcel of land located in or around watershed close to poultry farms [].These practices have resulted in nutrient runoff and leaching and   Nonpoint Source Guidance and Technical Assistance. Best Management Practice (BMP) is a term used to describe pollution control systems that treat, slow, divert, or capture nonpoint source pollutants. BMPs are the actions on the ground that help to improve and restore water

      Goals / Objectives This project focuses generally on the policy design implications of factors characterizing non-point source pollution: information asymmetries, incomplete information, and stochastic emissions. For example, nutrient runoff from crop production is a significant source of water quality impairment in the U.S. Designing policies to improve water quality (at least in part / This book is geared to environmental specialists and planners, heavy on the technical side. It goes beyond tranditional nonpoint source (NPS) approaches which typically only look at stormwater as athe sole NPS pollution driver. There is some overreaching material beyond the context of NPS and its control; however, this material is still sound pollution abatement  › EPA Home.

Empirically-based simulation modelling of NPS pollution goes back at least to when the published their “Nonpoint Source Pollutants Loading Model” (Donigian and Crawford, ).The many empirical studies of sediment and chemical runoff processes in agricultural systems at different scales (plot, field, catchment, river basin) across North America, led to major developments in Assessment of rural nonpoint source pollution.

Published under licence by IOP Publishing Ltd IOP Conference Series: Earth and Environmental Science, Vol conference Nonpoint source pollution control and stormwater management are two objectives in managing mixed land use watersheds like those in New Jersey.

Various best management practices (BMPs) have been developed and implemented to achieve both objectives. This study assesses the cost-effectiveness of selected BMPs for agricultural nonpoint source pollution control and stormwater management in the Estimates of non-point source (NPS) contribution to total water pollution in China range up to 81% for nitrogen and to 93% for phosphorus.

We believe these values are too high, reflecting (a) misuse of estimation techniques that were developed in America under very different conditions and (b) lack of specificity on what is included as NPS. We compare primary methods used for NPS estimation in The non-point source (NPS) is the main cause of surface water pollution in Taihu Lake basin in southeast China, therefore the quantitative analysis for the effects of NPS on water environment is the vital basis for water pollution control in the ://().
