The target analyzes the features of rationing the content of chemical pollutants, heavy metals in surface waters, and the results of basic monitoring of these groundwaters. To identify chemical pollutants, several nuclei of the studied region are examined. The paper considered the issues of the ecological state of underground water under the influence of anthropogenic (in particular, industrial production) impacts.

Quality Of Water

<p>Na Região do Semiárido nordestino a diminuição da disponibilidade dos recursos hídricos superficiais tem levado a população da zona rural a buscar, nos recursos hídricos subterrâneos, a solução de seus problemas de abastecimento, o que tem acarretado um crescimento no número de perfurações de poços tubulares profundos. O trabalho objetivou avaliar a qualidade de águas utilizadas para consumo humano em áreas rurais da região de Boa Vista, Paraíba. As amostras de água foram coletadas em poços tubulares, em dois períodos: 4º trimestre de 2014 e 2º trimestre de 2015. As variáveis avaliadas foram: pH, CE, Ca, Mg, Na, K, HCO<sub>3 </sub><sup>-</sup>, Cl, alcalinidade e dureza total e SDT. Das águas analisadas 94,55% são consideradas salgadas nas duas amostragens. Em sua maioria os teores de dureza, alcalinidade, cloreto, magnésio, sódio e potássio estão fora do limite estabelecido pela Portaria vigente no país. Com relação ao pH, as amostras se encontram dentro do padrão normal.</p><p align="center"><strong><em>Water quality for human consumption in rural communities in the municipality of Boa Vista, state Paraíba</em></strong></p><p><strong>Abstract</strong><strong>: </strong>In the semi-arid northeastern region of decreasing availability of surface water resources has led to population from the countryside to look for underground water resources to solve their supply problems, which has led to an increase in the number of deep wells drilling. The study aimed to assess the quality of water used for human consumption in rural areas of the region Boa Vista, Paraíba. Water samples were collected from wells in two periods: 4th quarter 2014 and 2nd quarter of 2015. The variables evaluated were: pH, EC, Ca, Mg, Na, K, HCO<sub>3</sub><sup>-</sup>, Cl, alkalinity and total hardness and TDS. 94.55% of the analyzed waters are considered cured in the two sampling. Mostly hardness levels, alkalinity, chloride, magnesium, sodium, potassium are beyond the limit set by current Ordinance in the country. Regarding the pH samples are within the normal pattern.<strong></strong></p>

The article deals with the problems of surface waters in the Khanty-Mansi Autonomous Okrug-Yugra, which contain a large amount of oil products and phenols. Oil is the most dangerous pollutant for water resources. The land "flavored" with oil dies for several decades, oil oppresses soil biota, pollutes surface and ground waters. We need innovative purification methods and technologies to purify and improve the conditions of water.

Abstract The oasis of Moghrar is located in the wilaya (province) of Naama, in the southwest of Algeria. It is well known for its Ksours, its palm groves and the good quality of its fruit and vegetables, especially the dates and their varieties. This region contains important groundwater and surface water resources. For several centuries, domestic water supply and irrigation have been carried out using traditional techniques of water harvesting such as pendulum wells and foggaras. Currently, this hydraulic heritage is meeting technical and social problems, particularly with the contribution of drilling and motor-pumps. The main issues are water table drawdown, the drying-up of water sources and degradation and decay of traditional techniques. The objective of this study is to make an inventory of all water sources in the study area, to study the impact of the contribution of modern techniques on ancestral techniques and finally to propose recommendations for safeguarding the hydraulic heritage.

Abstract. This work is part of a program to study and monitor the impact of human activities in the cities of Missour and Outat El Haj on the quality of the surface waters of the average Moulouya (Morocco).The aim of this study is to evaluate in time and space, the degree of metallic pollution of surface water of the average Moulouya during the period (September 2014, January, April and July 2015). The results of this study suggest that the waters of the ten stations in the study area are relatively contaminated with heavy metals. The contents of the analyzed metals are high and variable in the wastewater of the cities of Missour and Outat El Haj and in the waters of the Moulouya average.The anthropogenic impact on the ecosystems selected for this work is highlighted by: the high metallic contamination of the water of the stations located downstream of wastewater discharges of the cities of Missour and Outat El Haj, and the variation of the contents according to an increasing concentration gradient from station M1 to M9.

The Peninsula of Sithonia is one of many typical regions in Greece in which overexploitation of local aquifers has led to several serious problems related to quantity and quality degradation of groundwater reserves. In this paper, a management plan is presented that aims at the utilization of the so far unexploited surface water resources of the area in order to restore the degraded aquifers and to supplement the groundwater supplies, mostly for domestic use. To this end the total municipal water demand and the potential of surface waters are first estimated at both the local and regional levels. Next, four alternative management schemes are examined, each one consisting of a different number of reservoirs. A preliminary evaluation of these water supply alternatives, that concludes the paper, is based on both operational and economic factors in order to facilitate a future multi-criterion decisionmaking analysis.

Climatic changes influence on surface water resources directly and in that way, more or less, more quickly or more slowly, by means of waterfalls, the quantity and quality of ground waters or hydrogeological resources, namely their sustenation. The conclusion about the influence of climatic changes on ground waters can be drawn on the basis of isotope research (2H, 14C) by means of which their origin and age are determined most reliably. Present investigation results of the origin and age of ground water resources at the most famous hydrogeothermal regions, as well as the sustenance forecast of their quality and reserves depending on still existing and future climatic changes will be shown in this paper.
