Abstract. Summarizing the scientific publications and production reports of enterprises that studied the environmental status of the Prut River in the last decades, as well as relevant reports in the periodical press and other media, it has been found that the quality of its water in the upper reaches is significantly deteriorating. The purpose of this article was to assess the quality of water in the Prut River in the upper flow according to various methods (including the complex of environmental indexes) to determine the degree of its pollution. The article presents the results of calculations of the complex ecological index (Ie) for assessing the water quality of the Prut river in the vicinity of the city of Yaremche. To establish sources of pollution of this river, an experimental study of the physical and chemical parameters of its water was carried out. A series of water samples from the Prut River in the area from the village Dora (suburb of Yaremche). upstream to the village Tatariv is studied laboratoryally. Samples were selected at six points of observation. The studies were conducted in two seasons: fall (september) and winter (january). The main pollutants and their concentrations in the selected samples are determined. Modern laboratory techniques and equipment are used for laboratory research. On the basis of laboratory examination of water samples from the river Prut in the upper reaches (the outskirts of the city of Yaremche) it was established that the water in this area is sufficiently clean; excess MPC value is not observed. An exception may be only a sample of water within the city of Yaremche, where there are increased concentrations of phosphates. It is also shown that winter water samples contain slightly more pollutants (including biogenic ions) than autumn. These facts may also be partly explained by the increase in airborne acid oxide emissions and their interaction with river water. According to the results of calculating the complex ecological index it was established that the Prut River water in the studied area belongs to the 2nd class of quality (the state is good). Separate samples from the control section within the city of Yaremche showed an increased value of the complex ecological index (Ie is 3.21 and 3.36 for the summer and winter series, respectively). The reason for this increase in the index is the pollution of the Prut River in the studied area due to the increase in anthropogenic pressure on it over the past years.

The article is devoted to the problems of studying the quality of drinking water from decentralized water supply sources of rural settlements. The preparatory stage of the study included: creation of a cartographic basis of the settlement; field reconnaissance routes; express analysis of drinking water quality; creation of situational plans of wells locations, and the basis for the ecological passport of the source of decentralized individual water supply (well). The relevance of the study is due to the deterioration of the quality of water as a source of domestic water supply. This is especially true for the rural population. There is a need to conduct an inventory and certification of wells in accordance with European standards and requirements, as well as modern technical and information capabilities. The ecological passport of a natural object is a system of diagnostic characteristics that allow one to get an idea of its condition and develop ways to improve it. In the process of researching the issue of certification of drinking water sources, we analyzed the accounting systems of these facilities in Canada and Germany. Our sample environmental passport was developed based on a study of groundwater in the village of Poromiv, Volyn region of Ukraine. The quality of drinking water is influenced by both the natural factors – geological structure and climate, and the intensive economic development of the surrounding area. The sample consisted of 40 wells. We used theoretical research methods: analysis, synthesis, abstraction and idealization. Such approaches implied the search for relationships between topological, hydrological and chemical parameters of individual observation points, as well as the ability to build idealized regression models to delineate areas for certification and detailed research. The formation of the information database was carried out using the methods of empirical knowledge. In particular, visual observations have identified potential sources of contamination (private farms – livestock sites, latrine pits, farmland, and infrastructure). They can affect the condition and quality of water in wells. With the help of a level meter, pH-meter, TDS meter and rapid tests for nitrates, the measurements of qualitative indicators that determine the overall hydrochemical state of groundwater were carried out. The general observations revealed non-compliance with the norms of placement of these objects. In particular, in many cases the norms of distance from sheds (more than 20 m) and cesspools (more than 50 m) relative to wells were violated. In addition, there is a general tendency to neglect the rules of formation of cesspools and manures, which contributes to the ingress of pollutants into the soil and subsequently into groundwater. In general, the accounting of wells and their diagnostic characteristics was developed in the form of a database in the ArcGIS environment and a passport of a separate source of water supply. It is proposed to add a situational plan with the location of the water supply source for the main polluting objects to the general technical characteristics. The number of indicators in the passport table can be adjusted depending on the potential sources of pollution and the abilities to monitor the water quality of a particular water user. The purpose of forming documentation of this type is to account and record the problems arising in the arrangement, location and operation of the well for their further solution. This will be the basis for identifying areas vulnerable to nitrate contamination. We identified a number of violations in the location of water supply sources in relation to economic facilities and structures within the study area, which was reflected in the increase of general hydrochemical indicators. Relationships between building density and quantitative values of pH, mineralization and nitrate content were recorded. The final step of the research is to identify problematic sources of decentralized water supply from the viewpoint of population ecological well-being, as well as to develop proposals for the community and individual owners to improve the quality of drinking water. Keywords: well, water supply, ecological passport, sources of pollution.

Digoel river have an important role to the human activity and environment in Boven Digoel Regency. Increasing of human and industrial activity around the watershed of Digoel River were suspecious to cause the degradation water quality in Digoel River. This research was done to monitor the impact of the industrial activity to the quality of water in outlet of waste water treatment plant(WWTP) of PT. Korindo to the water quality of Digoel River. Parameter analised are the physical, chemical, organic chemical, microbiology and metal content in water. Analysis of the water quality accordance to PP Nomor 82 Tahun 2001 about water quality managementand water pollution and Permen LH Nomor 5 tahun 2014 about the quality of waste water.The monitoring was conducted in three months at five sampling stasion (river upstream, river down stream, outlet WWTP plywood, outlet WWT workshop, outlet WWTP palm oil) in Districk Jair. The rsult showed, parameter of BOD, COD, phospate, phenol and total coliform in Digoel River exceeded class I of water quality standards. Outlet of plywood WWTP have two parameters that exceed the quality standard which were TSS 15.67 mg/L and phenol 13.33 mg/L.The outlet of WWTP workshop have four pameter exceeded the quality standard which were TSS (383.67 mg/L), oil/fats (502.0 µg/L), phenol (11.0 µg/L), and zinc (21,000 mg/L). IPAL oil WWTP outlet have two parameter sexceeded the quality standars which were oil/fats (313.0 µg/L) and total coliform (> 979 cells/100 mL). The result indicating  that the status of water quality of Digoel River are categorized as “lightly polluted”. Therefore based on utilization, it was categorized as class IV water quality that can be used for irrigating, planting and other purposed that meet the requairement of water qualiy in this class, while for other uses need necessary processing. In order  not to  increase the pollution in the Digoel river the WWTP of industry around Digoel River should improved their treatment, so that waste water discharged to the Digoel River not exceed the stanards quality.Key words: water quality, digoel river, status of water quality, pollutant index.

Abstract The general approach to water quality studies in Gulf Canada petroleum refineries is described and illustrated by typical results from one refinery. Some of the studies were carried out using a Mobile Water Conservation Laboratory on site whilst others involved grab sampling and transportation to a central laboratory. The studies were carried out with the objective of evaluating the efficiency of existing waste water treating systems to produce effluent of quality which will meet modern environmental requirements set by the Federal Government. These include oil, suspended solids, sulfide, ammonia, phenols, pH and a fish toxicity requirement. The quality of the effluents of several large and complex refineries was monitored, performance of waste water treating units was determined and pilot plant data of new packaged units was collected for future uses. Emphasis was placed on treating units which are used to treat waste streams and effluents for oil and suspended solids removal.

Water pollution is caused in rural areas, especially by uncontrolled wastedeposits located in river bed and in urban areas is discharged, irregular,untreated sewage. The Cuejdiu River is a tributary of the Bitriţa River inthe left side,with a total length of 24 km. Evaluation of water quality of the CuejdiuRiver was achieved by processing the results obtained from tests analyzedfor 30 samples, taken on March 17, 2012, between the mouth of the RiverBestriţa and upto the exit of the village Cuiejdi. Analysis of water samples was performedin the laboratory of the Department of Geography, at the Faculty ofGeography and Geology and was taken into account several parameters such asconductivity, pH, total acidity, nitrates, chlorine. The values obtainedwere cartographically represented to highlight differences between thesector that cross of the rural area and the sector located in the urbanarea. Water Management System Neamţ realizes assessments of the ecologicaland chemical status of the river Cuejdiu only in urban areas, classifyingwater quality in relation to general indicators. Thus, data obtained over aperiod of 10 years, from 2000 to 2010, and performing through charts,helped us to observe the time evolution of water quality in the area. Theimpact of human activities is evident in both urban and rural areas. In theurban area the connections made by citizens, particularly those who live onthe ground blocks, to the rainwater system, instead of sewerage systems,lead to the degradation of water quality. As regards the rural area, thesituation is just as difficult, meaning that the waste discharged into theriverbed changes the chemical composition of water.
