This work aimed to evaluate the quality of surface water around the Manaus Solid Waste Landfill (ARSM), in which it is located near important waterways in a growing urban expansion area.  During the collection period, the parameters pH, T, fecal coliforms, OD, DBO5, nitrate, phosphate, turbidity and total solids were monitored, where these are the main parameters for performing water quality index calculations. The results analyzed indicate contamination in the streams near the perimeter of the Landfill, where the possible origins for non-conformities can be problems in draining the leached and waterproofing system of the landfill ponds. The recovery of the quality of these water resources is essential, since it is an area with flora and fauna that are heritage, not only of the residents who occupy their surroundings, but also the population of Manaus who in the past enjoyed bathing and fishing areas in the streams currently affected by the slurry produced in the landfill.

The ecological assessment of the quality of surface water of the Dnipro basin (within Zhytomyr region) is carried out. In general, surface water of rivers of teter, rotten, Guiva, forest stone, Irsha, Human, Arpin, Rostavitsa and Kamyanka were investigated. The study was conducted according to systematic observations based on the ecological classification of the quality of surface water and estuates in Ukraine, which includes a set of hydrophysical, hydrochemical, hydrobiological and other indicators reflecting the peculiarities of components of aqueous ecosystems. On the basis of unified ecological criteria, the technique allows you to compare the water quality in separate areas of water objects, in water objects of different regions. The calculation of the ecological assessment of water quality was carried out within three blocks: a block of saline composition (I1), a block of troph-sanitary (ecological-sanitary) indicators (I2) and a block of indicators of specific substances of toxic action (I3). The results are presented in the form of a combined ecological assessment, based on the final conclusions of three blocks and is to calculate the integral ecological index (IE). The results of observations on the qualitative state of surface water in the Tetereva Basin, the right tributaries of the Dnieper “Good”, “clean” water (II class of quality) here are less than half (47%) of all observation points. Such a quality is the water of the rivers of Irsha, Guiva, rotten, varnia, teter. In 6% of cases, “satisfactory”, “contaminated” water of the quality of the quality (3,7 ≤ IE ≤5,4), namely: r. Teters, within the city of Zhytomyr, 200 m above the fall of the River Forest Kamyanka and River Forest Kamenka, within the city of Zhytomyr, 100 m above the fall in Teter. Waters of all other research points occupy an intermediate position between II and III of quality classes and are evaluated as “good”, “clean” and “satisfactory”, “contaminated”. The water of the pools Irpen and dew, represented by the rivers Irpin, Rostavitsa and Kamenka, are characterized by the second class of quality “good”, “clean”. Executed researches allowed to analyze and evaluate the ecological state of the rivers of the rivers of the Zhytomyr region within the Dnipro River basin, which will establish the environmental standards of water quality and to determine the basic areas for improving the state of water resources and substantiate the system of recommendations aimed at improving the environmental state of the basins under study in the boundary of the area.

Phosphorus is an essential component of modern agriculture. Long-term land application of phosphorous-enriched fertilizers and animal manure leads to phosphorus accumulation in soil that may become susceptible to mobilization via erosion, surface runoff and subsurface leaching. Globally, highly water-soluble phosphorus fertilizers used in agriculture have contributed to eutrophication and hypoxia in surface waters. This paper provides an overview of the literature relevant to the advances in phosphorous management strategies and surface water quality problems in the U.S. Over the past several decades, significant advances have been made to control phosphorus discharge into surface water bodies of the U.S. However, the current use of phosphorus remains inefficient at various stages of its life cycle, and phosphorus continues to remain a widespread problem in many water bodies, including the Gulf of Mexico and Lake Erie. In particular, the Midwestern Corn Belt region of the U.S. is a hotspot of phosphorous fertilization that has resulted in a net positive soil phosphorous balance. The runoff of phosphorous has resulted in dense blooms of toxic, odor-causing phytoplankton that deteriorate water quality. In the past, considerable attention was focused on improving the water quality of freshwater bodies and estuaries by reducing inputs of phosphorus alone. However, new research suggests that strategies controlling the two main nutrients, phosphorus and nitrogen, are more effective in the management of eutrophication. There is no specific solution to solving phosphorus pollution of water resources; however, sustainable management of phosphorus requires an integrated approach combining at least a reduction in consumption levels, source management, more specific regime-based nutrient criteria, routine soil fertility evaluation and recommendations, transport management, as well as the development of extensive phosphorus recovery and recycling programs.

Abstract The environmental assessment of the surface water quality of the Western Bug River has been made using the system of classification quality of land surface water of Ukraine in accordance with the approved methodology, which allows comparing water quality of separate areas of water objects of different regions. The calculation of the environmental assessment of water quality has been carried according to three blocks: block of salt composition, block of trophic and saprobic (ecological and sanitary) indicators and block of indicators of content of specific toxic substances. The results are presented in the form of a combined environmental assessment, based on the final conclusions of the three blocks and consists in calculating the integral ecological index. Comprehensive studies of changes in the water quality of the Western Bug River have been conducted within the territory of Ukraine for a long-term period. The water quality of the river on the final values of the integral indicators of the ecological condition corresponded mainly to 4nd category of the 3rd class – the water is “satisfactory” by condition and “little polluted” by degree of purity (except for points of observation that located within the Volyn region, where the water quality corresponded to 3rd category and the 2nd class. It is “good” by condition and “fairly clean” by the degree of purity). Visualization and part of the analysis are performed using GIS technologies in the software of the ArcGIS 10.3.
