  • Water Quality Attribution and Simulation of Non-Point Source Pollution Load Fux in the Hulan River Basin Yan Liu1,2, Hongyan Li1,2*, Geng Cui3 & Yuqing Cao1,2
    www.nature.com/scientificreports OPEN Water quality attribution and simulation of non-point source pollution load fux in the Hulan River basin Yan Liu1,2, Hongyan Li1,2*, Geng Cui3 & Yuqing Cao1,2 Surface water is the main source of irrigation and drinking water for rural communities by the Hulan River basin, an important grain-producing region in northeastern China. Understanding the spatial and temporal distribution of water quality and its driving forces is critical for sustainable development and the protection of water resources in the basin. Following sample collection and testing, the spatial distribution and driving forces of water quality were investigated using cluster analysis, hydrochemical feature partitioning, and Gibbs diagrams. The results demonstrated that the surface waters of the Hulan River Basin tend to be medium–weakly alkaline with a low degree of mineralization and water-rock interaction. Changes in topography and land use, confuence, application of pesticides and fertilizers, and the development of tourism were found to be important driving forces afecting the water quality of the basin. Non-point source pollution load fuxes of nitrogen (N) and phosphorus (P) were simulated using the Soil Water and Assessment Tool. The simulation demonstrated that the non-point source pollution loading is low upstream and increases downstream. The distributions of N and P loading varied throughout the basin. The fndings of this study provide information regarding the spatial distribution of water quality in the region and present a scientifc basis for future pollution control. Rivers are an important component of the global water cycle, connecting the two major ecosystems of land and sea and providing a critical link in the biogeochemical cycle.

  • Diffuse Pollution, Degraded Waters Emerging Policy Solutions
    Diffuse Pollution, Degraded Waters Emerging Policy Solutions Policy HIGHLIGHTS Diffuse Pollution, Degraded Waters Emerging Policy Solutions “OECD countries have struggled to adequately address diffuse water pollution. It is much easier to regulate large, point source industrial and municipal polluters than engage with a large number of farmers and other land-users where variable factors like climate, soil and politics come into play. But the cumulative effects of diffuse water pollution can be devastating for human well-being and ecosystem health. Ultimately, they can undermine sustainable economic growth. Many countries are trying innovative policy responses with some measure of success. However, these approaches need to be replicated, adapted and massively scaled-up if they are to have an effect.” Simon Upton – OECD Environment Director POLICY H I GH LI GHT S After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, i.e. pollution from surface runoff, soil filtration and atmospheric deposition. The relative lack of progress reflects the complexities of controlling multiple pollutants from multiple sources, their high spatial and temporal variability, the associated transactions costs, and limited political acceptability of regulatory measures. The OECD report Diffuse Pollution, Degraded Waters: Emerging Policy Solutions (OECD, 2017) outlines the water quality challenges facing OECD countries today. It presents a range of policy instruments and innovative case studies of diffuse pollution control, and concludes with an integrated policy framework to tackle this challenge. An optimal approach will likely entail a mix of policy interventions reflecting the basic OECD principles of water quality management – pollution prevention, treatment at source, the polluter pays and the beneficiary pays principles, equity, and policy coherence.

C. 20002 i QUESTION PRESENTED In the Clean Water Act (CWA), Congress distin- guished between the many ways that pollutants reach navigable waters. It defined some of those ways as “point sources”—namely, pipes, ditches, and other “discernible, confined and discrete conveyance[s] … from which pollutants are or may be discharged.” 33 U.S.C. § 1362(14). The remaining ways of moving pollutants, like runoff or groundwater, are “nonpoint sources.” The CWA regulates pollution added to navigable waters “from point sources” differently than pollution added “from nonpoint sources.” It controls point source pollution through permits, e.g., id. § 1342, while nonpoint source pollution is controlled through federal oversight of state management programs, id. § 1329. Nonpoint source pollution is also addressed by other state and federal environmental laws. The question presented is: Whether the CWA requires a permit when pollu- tants originate from a point source but are conveyed to navigable waters by a nonpoint source, such as groundwater.

  • Physics 1CL · WAVE OPTICS: INTERFERENCE and DIFFRACTION · Winter 2010
    Physics 1CL · WAVE OPTICS: INTERFERENCE AND DIFFRACTION · Winter 2010 Introduction An important property of waves is interference. You are familiar with some simple examples of interference of sound waves. This interference effect produces positions having large amplitude oscillations due to constructive interference or no oscillations due to destructive interference which can be considered to arise from superposition plane waves (waves propagating in one dimension). A more complicated behavior occurs when we consider the superposition of waves that propagate in two (or three dimensions), for instance the waves that arise from the two slits in Young’s double slit experiment. Here, interference produces a two (or three) dimensional pattern of minima and maxima that depends on the relative position of the interfering sources and on the wavelength of the wave. The Young’s double slit experiment clearly shows that light has wave properties. Interference effects are important because they are the basis for determining the positions of atoms in molecules using x-ray diffraction. An interference pattern arises from x- rays scattered from the individual atoms in a molecule. Each atom acts as a coherent source and the interference pattern is used to determine the spatial arrangement of the atoms in the molecule. In this lab you will study the interference pattern of a pair of coherent sources. Coherent sources have a fixed phase relationship at all times. Several pairs of transparences are provided to facilitate the understanding and analysis of constructive and destructive interference. The transparencies are constructed to mimic the behavior of a pair of harmonic point source wave trains.

INTRODUCTION The Ninth Circuit Court of Appeals recently held in Oregon Natural Desert Ass'n v. Dombeck I ("Dombeck") that "certifica­ tion under Section 401 of the Clean Water Act is not required for grazing permits or other federal licensed activities that may cause pollution solely from nonpoint sources. "2 The court not only excluded grazing from the certification requirement under Section 401 of the Clean Water Act (the Act), but also ruled that all discharges from solely nonpoint sources are ex­ cluded from the state certification process.3 By upholding the validity of the grazing permit in the absence of state certifica­ tion, the court substantially limited states' ability to regulate nonpoint source pollution originating on federal lands.

Best Management Practices (BMPs) can reduce NPS pollution delivery to receiving waters. For economic reasons, BMPs should be placed at critical source areas (CSAs), which are the areas contributing most of the NPS pollution. The CSAs are the areas in a watershed where source coincides with transport factors, such as runoff, erosion, subsurface flow, and channel processes. Methods ranging from simple index-based to detailed hydrologic and water quality (HWQ) models are being used to identify CSAs. However, application of these methods for Canadian watersheds remains challenging due to the diversified hydrological conditions, which are not fully incorporated into most existing methods. The aim of this work is to review potential methods and challenges in identifying CSAs under Canadian conditions.
