Introduction: water management is of paramount importance in productive activities, such as agriculture, livestock and industry, due to its direct impact on both the quality and the availability of this valuable resource. However, groundwater management is usually addressed under a non-integrated approach which originates a high risk of pollution as well as water shortage for food and animal production in the agro-industrial systems. Objective: to analyze water quality for human consumption, hydrogeological features, water demand, and discharge of liquid effluents on soil and surface water. Methods: we carried out a diagnostics of water management in an agro-industrial school located in Buenos Aires province, Argentina. The production system includes a bovine dairy farm; calf, pork and rabbit breeding; beekeeping; poultry farming; dairy and cheese factory; agriculture and fodder area; processing of meat, and orchard. To perform the analysis, we calculated water requirements for six productive activities and evaluated the hydrological features of the area through water table measurements considering the groundwater flow sense. We analyzed the groundwater quality seasonally during a period of a year through five water samples. We considered microbiological and physicochemical parameters and they were compared with recommended level by law, and we carried out the monitoring of residual chlorine during a week. Also, we evaluated the generation and disposal of effluents. Results: water was suitable for human consumption, although we detected variations in its quality indicators. We determined that the main issues hindering an integrated water management were the diversified production developed with high volumes of water demanded, the water quality deterioration by the agro-industrial productions carried out, and the hydrogeological features of the area. In addition, we measured a high water demand which is in conflict with groundwater shortage and the complex hydrological conditions of extraction in the studied area. Conclusion: this study demonstrated the usefulness of applying effective strategies to act on environmental-priority subjects and to develop good practices regarding water management from an integrated approach.

Health Diagnosis

Environmental health diagnosis was made in a sport and recreational park in the city of Guadalajara, Jalisco, Mexico. The objective of this research was to perform an environmental diagnosis in Tucson Park; it concentrated on air quality (fine and coarse particulate matter, carbon dioxide), environmental noise, water quality of springs and a pond according to national standards, and macroinvertebrates as biological indicators of water condition, as well as phytosanitary state of wooded area. Additionally, a survey was conducted to study environmental perception. Results of the study highlighted significant statistical differences concerning the amount and size of particles for the winter and spring seasons. Noise levels within the park premises exceeded the Mexican standard. Water quality measured through general criteria of integrated water quality index (WQI) qualified the park´s analyzed springs as acceptable but to abstain its use and human consumption. Finally, the perception survey identified insecurity as the major problem, followed by the lack of lighting and effective communication of courses and workshops for the community to attend. It is one of the first environmental diagnoses in sport parks in Mexico´s Metropolitan Areas as an integrated approach of ecosystem health and wellbeing of city inhabitants.

Sabendo que a água é um recurso natural essencial para as atividades humanas, estudos relacionados com seu uso racional e sustentável tornam-se fundamentais. Destinada ao consumo humano, a água deve apresentar características físicas, químicas e microbiológicas não prejudiciais à saúde, as quais são delimitadas por órgãos de saúde pública e caracterizadas como padrões de potabilidade. Assim, esta pesquisa teve como objetivo caracterizar a qualidade da água, avaliando características físico-químicas e microbiológicas que merecem consideração para o monitoramento ao analisar amostras diárias em pontos sorteados da rede de distribuição e em final de tratamento de um município do estado de São Paulo, no período de 2007 a 2011. Foram avaliados os parâmetros: residuais de cloro, pH, turbidez, cor aparente, flúor, temperatura da água, ocorrência de coliformes totais e bactérias heterotróficas. Para comparar a qualidade da água na rede de distribuição com sua qualidade na saída dos reservatórios (final de tratamento), considerando simultaneamente todas as variáveis envolvidas, utilizou-se técnicas de análise multivariada, mais especificamente, o teste T2 de Hotelling. Pretendeu-se aprofundar e melhorar a qualidade das informações e, também oferecer um procedimento metodológico não usual na área envolvida. Os resultados apontaram que o padrão de qualidade da água não se alterou entre o final de tratamento até a rede de distribuição (cavaletes das residências), destacando-se também, que esse procedimento multivariado pode ser utilizado como uma técnica de avaliação do padrão de qualidade da água nos diversos municípios e empresas de saneamento.PALAVRAS-CHAVE: Estatística multivariada, características físico-químicas, características climáticas. WATER FOR CONSUMPTION QUALITY COMPARISON IN BOTH DISTRIBUTION NETWORK AND FINAL TREATMENT RESERVOIRS ABSTRACT: Knowing that water is a key natural resource for human activities, studies related to the rational and sustainable use become crucial. Intended for human consumption, the water must have physical, chemical and microbiological characteristics not prejudicial to health, which are defined by public health agencies and characterized as potability standards. Thus, this study aimed to characterize water quality, assessing physical, chemical and microbiological characteristics and monitor it by analyzing daily samples in randomly selected points in the distribution network and the end of treatment of a municipality of Sao Paulo state in the period of 2007 to 2011. We evaluated the following parameters: residual chlorine, pH, turbidity, apparent color, fluoride, water temperature, occurrence of total coliform, and heterotrophic bacteria. To compare water quality in the distribution network with its quality in the reservoirs (end of treatment), while considering all the variables involved, we used multivariate analysis techniques, more specifically, the Hotelling's T2 test. We intended to increase the knowledge on water wuality,improve the quality of information and also offer an unusual methodological procedure in this area. The results showed that the standard of water quality did not change from the end of treatment up until the distribution network (easels residences). The multivariate procedure tested in this study can be used as an evaluation technique towater quality pattern in various municipalities and sanitation companies.Keywords: multivariate procedure, phisicochemical characteristics, climatic characteristics

Introduction. The drought in the Brazilian semiarid region has affected the quality of water. This study assessed the relationships between enteric parasitoses, water management, and water quality, correlating them with pluviometric seasonality.Methods. Cross-sectional surveys were carried out in four rural communities at the beginning of the dry season (n=151), at the end of the dry season (n=184), and in the rainy season (n=199), in order to collect sociodemographic data, human fecal samples, and samples of the water used for human consumption for physicochemical and microbiological analyses. In 2015, water filters were provided to 30 households under study.Results. There was an increasing trend in detection rates of commensal protozoa and theEntamoeba histolytica/Entamoeba disparcomplex at the beginning of the rainy season, with detection rates of 6% in 2014 and 21.6% in 2016.Giardia intestinalisandAscaris lumbricoidespresented distinct temporal distributions, which peaked in 2015: 20.1% and 30%, respectively. The proportion of inhabitants drinking inadequate water was 55% at the beginning of the dry season and 28.8% at the end of the dry season, reaching 70.9% at the beginning of the rainy season. The presence of filters reduced this proportion among those who received the hollow ceramic candle filter.Conclusions. Data suggest that the strategies to increase water supply in the Brazilian semiarid region can be ameliorated in order to improve the quality of drinking water.

The City

The City of Baltimore, Maryland is one of many US cities faced with challenges related to increasing potable water demands, diminishing fresh water supplies, and aging infrastructure. To address these challenges, the City recently undertook a $7M study to evaluate water supply and treatment alternatives and develop the conceptual design for a new 120 million gallon per day (MGD) water treatment plant. As part of this study, an innovative raw water management tool was constructed to help model source water availability and predicted water quality based on integration of a new and more challenging surface water supply. A rigorous decision-making approach was then used to screen and select appropriate treatment processes. Short-listed treatment strategies were demonstrated through a year-long pilot study, and process design criteria were collected in order to assess capital and operational costs for the full-scale plant. Ultimately the City chose a treatment scheme that includes low-pressure membrane filtration and post-filter GAC adsorption, allowing for consistent finished water quality irrespective of which raw water supply is being used. The conceptual design includes several progressive concepts, which will: 1) alleviate treatment limitations at the City's existing plants by providing additional pre-clarification facilities at the new plant; and 2) take advantage of site conditions to design and operate the submerged membrane system by gravity-induced siphon, saving the City significant capital and operations and maintenance (O&M) costs. Once completed, the new Fullerton Water Filtration Plant (WFP) will be the largest low-pressure membrane plant in North America, and the largest gravity-siphon design in the world.

A computer program based on expert system software was developed and proposed as a prototype model for water management to control eutrophication problems in receiving water bodies (Suzuki etal., 1988). The system has several expert functions: 1. data input and estimation of pollution load generated and discharged in the river watershed; 2. estimation of pollution load run-off entering rivers; 3. estimation of water quality of receiving water bodies, such as lakes; and 4. assisting man-machine dialog operation. The program can be used with MS-DOS BASIC and assembler in a 16 bit personal computer. Five spread sheets are utilized in calculation and summation of the pollutant load, using multi-windows. Partial differential equations for an ecological model for simulation of self-purification in shallow rivers and simulation of seasonal variations of water quality in a lake were converted to computer programs and included in the expert system. The simulated results of water quality are shown on the monitor graphically. In this study, the expert system thus developed was used to estimate the present state of one typical polluted river basin. The river was the Katsura, which flows into Lake Sagami, a lake dammed for water supply. Data which had been actually measured were compared with the simulated water quality data, and good agreement was found. This type of expert system is expected to be useful for water management of a closed water body.

This paper examines the administrative and legal structure of the wastewater sector in Turkey, identifying its shortcomings and their causes, and suggests solutions. The study begins by outlining the existing administrative and legal structure, then focusing on the areas where difficulties are faced and seeking solutions to them. Those administrative and legal facets which have produced improvements and/or function effectively have been analysed so as to provide examples for other areas. When examining the sector it was observed that problems common to every area are the failure to adequately define powers and responsibilities, the lack of coordination between sectoral organisations, and the fact that attention is generally concentrated on routine matters of secondary importance. The fact that numerous organisations share powers in the same area causes confusion. Plurality also creates difficulties where enforcement is concerned. The existence of more than one set of regulations relating to the same area gives rise to loopholes. At the same time, unrealistic, and hence unenforceable standards undermine the effectiveness of sanctions. It has been concluded that a single organisation should be invested with the legal powers to lay down the principles of water management, that environmental courts should be set up to enforce legislation by means of sanctions; and that for this purpose existing legislation should be reexamined and revised as necessary and/or brought up to date.
