Haizhou Bay is an open bay located in northern Jiangsu Province, China. This study analyzes the changes in the coastline, coastal development, and water quality of Haizhou Bay between 2006 and 2016. The box model method and numerical simulation are adopted to calculate the environmental capacities of Haizhou Bay in 2006 and 2016, analyze changes to environmental capacity features, and assess the influencing factors over this period. The scenario analysis method is used to discuss the influencing mechanism and degree of influence of factors (e.g., the water quality difference inside and outside the bay, and sea reclamation) on the environmental capacity and calculate the contribution of each influencing factor. The changes in terrain triggered by sea reclamation and water quality from 2006 to 2016 reduced the total environmental capacity of Haizhou Bay, with an influencing ratio of 0.198:0.802. In other words, poorer water quality inside the bay reduces the environmental capacity by a degree of 4.05 times that of sea reclamation. This study can offer guidance on related future research aiming to protect the marine environment of Haizhou Bay and control the total amount of pollutants discharged into the sea.

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.

Healthy coral reefs depends on the quality of the waters , so that research and monitoring of water quality becomes important. This research attempt to asses marine waters quality at kaledupa island and it’ s surrounding waters on October and November 2014. 33 In-situ samples were collected using multiparameters tool purposively which are categorized into  physical parameters (temperature, turbidity and clarity), and chemical parameters (DO, salinity and pH). Waters quality defined by STORET method based on Ministry of Living Environment decree number 115 year of 2003. Analysis geographically has been conducted to describe distribution of waters quality spatially. The result shows that Kaledupa waters has sustain slightly pollution, especially on DO, turbidity, temperature and salinity parameters which have deviated from standard values. The light pollution in Kaledupa waters is suspected caused by the entry of abundance organic matter and shallow bathymetry.
