Assessments of water quality in surface water bodies are increasingly incorporating both point and non-point pollutant sources. Water quality constituents are transported in the water as well as on the sediments. Predictions of constituent concentrations in the water and on the s...

Brazil is a country endowed with great superficial water reserves and aquatic biodiversity, despite its unequal distribution among diverse hydrographic regions. In view of the sustainable development concept established in many international environment and water treated, objecti...

The Pirangi beach is located in the eastern coastline of Rio Grande do Norte state, in the municipality of Parnamirim and Nísia Floresta. In it flow into Pirangi Watershed (PW), whose water receives large amounts of pollutants, mainly domestic and industrial sewage from districts...

The present work has detached the importance of application of statistical techniques for management water quality data. The goal of this work is to detect water quality variations and thus to relate water distribution systems problems in order to identify the need of preventive ...

There are a number of uses that involve the water consumption that are direct consequences of the industrialization and urbanization intensive process, as well as population growth. The sewage treatment plants serve as environmental barriers increasing the multiple uses of water....

The increasing population and industrial growth of the last century has compromised the quantity and quality of water resources. Brazil has instituted a National Water Resources Policy and outlined a Water Resources Plan; therefore, there is now a necessity to procure tools and m...

In the poultry industry, the use of water with adequate physical, chemical and microbiological quality it is of fundamental importance. Since many birds have access to the same water source, quality problems will affect a great number of animals. The drinking water plays an impor...

The water-quality modeling is an indispensable tool for the water resource planning and management. However, the current available models for the simulation of water-quality, as the QUAL2K, present structural and functional limitations. With the purpose of offering a tool that fa...

The relation between drinking water quality and diseases occurrence is already well known. In this sense, supplying safe water, that is, which matches the standards established by the legislation and does not represent any human health risk, is crucial to ensure the populations h...

In Brazil, human activities such as dumping of sewage, deforestation of riparian vegetation and inappropriate use of pesticides, have caused damage to the environment and water quality of rivers, especially when these rivers cut the large urban centers. The launch of fresh domest...

Eutrophication of water bodies is caused by high concentrations of phosphorus and nitrogen, leading to water quality declining. Accordingly, there is a concern to evaluate the quality of water for public supply. This research aims to show the dynamic behavior of the concentration...

To ensure quality of water for human consumption is a quality product and satisfactory quantity deserves proper attention, because it is presumed that water has their characteristics amended since the output of the treatment until the arrival for consumers, which can pose health ...

ABSTRACT Without effective actions to improve environmental management, water resources tend to become scarce. Thus, this study aimed to understand the processes influencing the physical, chemical, and biological properties of the water due to land uses and occupation in the Ipê ...

The legal biological survey of swimming pool waters is based on both the level of bacteriological contamination and the amount of material of fecal origin. The great number of soil amoebas and the occasional epidemiological risk involved led us to consider using these organisms a...

The development of anthropogenic activities without an adequate planning has provided the degradation of waters quality, compromising the several uses of this natural resource, as its utilization for recreational use. In this context, the county of Carrancas, located in the south...

ABSTRACT This study demonstrates using remote sensing, geographic information systems and multivariate statistics to study water quality in an agricultural watershed. The monitoring of water quality in the watershed of Lontras's river in the southwestern region of the State of Pa...

Water is essential for sustaining life on the planet and the dynamics of nature it permeates all the cycles of nature. The degradation of this resource affect the health, well-being of people, flora and fauna. In the characterization of water quality are determined various parame...

Water quality is one of the greatest challenges of the twenty-first century man, keep fresh water available, clean and safe water is one way to ensure good quality of life. Obtain means of monitoring the entry of pollutants, pesticides, industrial and domestic sewage, solid waste...

In rural areas, including rural schools, the water intended for human consumption may not have quality, due to problems in their capture and storage, leaving the rural population in the mercy of contamination and diseases of hydric veiculation. This work has the follows objective...

The human action can change aspects of water quality restricting the possible uses of water resources. It integrates the impacts of human activities, but in that regards it as a social concept. The research shows the results of water quality with a view to understanding the geoch...

In addition to human activities the water quality in reservoirs is influenced by weather and climate forcings that determine spatial and temporal variations in these systems. Conventional techniques for water quality monitoring require large time and fund investments. The synopti...
