In this paper, we want to check the quality of the drinking water in Kochani (in 2008). Our goal is to determine its chemical su itability. During one year (2008), we have analyzed 48 samples of crude water taken from springs, 44 samples of water taken right before its entering into the factory, 29 samp les of water taken right after its exiting of the factory and 262 samples taken from the water supply network in 5 randomly chosen places.

Leakages from underground storage tanks and accidental spills have led to contamination of soils and groundwater with organic solvents. Bio-monitoring (phyto- monitoring) uses plant tissue concentrations of organic pollutants in deep-rooted species of trees for low-cost assessment of the groundwater concentrations. Disadvantages of this approach include the limite d number of said tree species in the contaminated area, and the limited number of core samples that can be taken from a single tree before it dies. A so...

THMs in disinfection by products are especially important because of their potential carcinogenity.

Climate change can alter the demand for water, with demands increasing during dry, warm periods and decreasing during cool, wet periods. Climate change may impact a municipality’s ability to provide water to existing customers and their planning for the future. New sources of water may be required, and the evaluation of these new sources should consider potential climate change. Land use activities exert pressure on water resources. To anticipate this change in climate and land use activities and to assess its i...

It is known, that there are two qualitatively different sources of supply of Tbilisi by potable water - underground (artesian wells near settlements Natakhtari, Bulachauri, Mukhrani) and surface (Tbilisi reservoir filled with waters of the rivers Aragvi and Iori). The work gives the values of the main ions (Ca2+, Mg2+, SO4 2-, Cl-, HCO3-, CO3 2-) and water hardness in drinking (tap) water in different districts of Tbilisi city (the largest settlement in Georgia). There have been received the values of concentratio...

The reservoirs created behind dams built on the main interior rivers of Romania as well as on the Danube have increased the country’s available volume of usable water. The reservoirs’ location and the way they were managed resulted in a decrease of the retention capacity, due to large quantities of sediments accumulated in these lakes. The reservoirs on the rivers Bistriţa, Buzău, Ialomiţa, Argeş and Olt have been affected the worst by the silting process. On average, the values range from 0 - 25\% of the ...

This paper highlights the fact that environmental issues in the border regions are numerous. These problems in border regions are endemic to many countries. At global scale of the whole planet, the importance of transboundary pollution of the air, water, soil is far from negligible (according to reports submitted to the UN). Almost 50\% of our planet earth (excluding Antarctica) is located in international water collection tanks. In this area about 40\% of world’s population lives, stretching over more than 200 ...

As the water has a vital role in human life and economic development, its shortage can cause some economical, agricultural, industrial and environmental problems. These problems are more prominent in warm and dry regions. Therefore, in such areas the water resources management as well as the treatment and recycling of the mine drainage have the great importance. In the underground and open pit mines, we usually deal with the huge amounts of the contaminated water. In this research, by considering of the statistics...

This paper aims to reflect some concerns regarding the waste management and to highlight its peculiarities.

The authors present the update stage of Braila Plain water resouces. Within the surface waters, the Buzau, Siret, Calmatui rivers as well as the Danube are included, as they are water suppliers for Braila Plain, in the absence of other important water resources. The lakes are few in number, with a low volume of water and a high chemism. The smalldepth underground waters exist as a continuously ground water layer and the high-depth ones are found especially in the Fratesti layers, but these have a high mineralizati...

The water pollution on marine ecosystems could cause health problems through water contamination and in a direct contact, when used for recreation aims, or in indirect way, by the negative impacts to marine ecosystems and by consuming of polluted marine products. The samplings of marine water (2007) are taken from the stratum water surface about 10 cm, at a distance 10-20 m by sea coast. At sandy beaches, where water depth in sea coast is shallow, water samples are taken at distance 10-30 m from sea coast with wat...

One of the main purposes of GIS is to provide organization with increased information and analyzing spatial data. A GIS can become increasingly more valuable in prediction of quantitative or qualitative variables in no measured locations when coupled to Artificial Intelligence (AI). ANN is one of the AI fields that is a highly simplified model for the biological structure of a human brain. An ANN when linked to GIS, can be useful for evaluating, monitoring, decision making and of course predicting. In this study, ...

Novel or accelerated global changes call for local action. The question on how to adapt to global change led recently to the formulation of a number of national and regional adaptation strategies to climate change. Beside climate, however, also other aspects as land use, agricultural markets and social structures are affected by and in return influence the perpetual global change. The steady interaction between regional development and global change further complicates a holistic strategy formulation. In order to ...

The climate change due to global warming is accepted among the greatest environmental problems resulted from the human effects of increasing energy consumption, urbanization and deforestation events threatening the healthy life of people and environment. Many results of the climate change due to global warming can be estimated as the melting of snow covers, terrestrial and sea icebergs, replacement of climate zones, frequent formation of severe weather events, floods that gain strength in time, severe droughts, fo...

Mining in upper Me\vza valley had more than 350 years of tradition. Lead and zinc ore deposit was developed in the triassic carbonate layers on the area of 64 km2. Until 1994, when the mining process was stopped, miners excavated about 19 million tons of lead and zinc ore and over 1000 km of galleries and pits. A crucial aspect of the Me\vzica mine was the dewatering issue. Me\vzica ore deposit is developed in Triassic carbonate rocks – limestone and dolomite. The area is of rough mountainous relief rising from ...

Almost any places in the world, people are using groundwater for drinking and usage needs because of reduced surface and spring waters sources in last decate. Settlement areas, agricultural areas, solid waste areas, industrial areas, waste water discharge areas have always potential to pollute the aquifer media. Boreholes areas for abstracting the ground water has to be picked up not to be carrying risk getting pollution on surface. So it’s necessary for the engineers that hydrogeologic properties has to be choo...

Methods of estimating yield from ungaged watershed may be by using of climatic factors, only geographic location and watershed and climatic factors. Methods for estimating yields, as regional analysis, water accounting, direct runoff method, climatic and geographic factors, should be considered as giving estimates so broad that the influence of specific factors have large margins or error. Hydrologic simulation models in watershed modelling use mathematical equations to calculate results like runoff volume or peak...

Naturally occurring arsenic (As) in groundwater of sedimentary aquifer has emerged as a global problem, and issue of major environmental health concern. Most groundwater from the Terai Basin of Nepal is contaminated by excess arsenic. Such groundwater is widely used for drinking and irrigation purpose and makes easy means of direct entrance of arsenic into human body and food chain; and that affects human health adversely. This paper evaluates the state of arsenic contamination in the six Terai districts of Nepal ...
