The increasing use of detergents as cleaning agents in the community potentially result in pollution of the water environment, this is supported by the quality of the well water having a high mineral hardness. When cleaning agents flow into waters through the river, it had a negative impact on the environment and health. The results showed that pollutant loads actually came from the use of detergent in 55 households at 0,323 mg/lt/month or 5,924 mg/day, while the standard maximum pollutant load of detergent waste at 0,0016 mg/lt/month or 0,0292 mg/day. The results concluded that the pollutant load value in this research was higher than maximum pollutant load value, suggesting that pollutant load of detergent waste provided high contribution to pollution of the land and waters in such area, thereby the surface water quality decreased ground water quality, incidence of some disease such as diarrhea, heavy metal poisoning and skin disease. Therefore, it is recommended that households use environment-friendly detergents because it is easier to biodegrade. They should make simple domestic waste treatment equipment using biofilter technique.

Model Predictions

A river water quality spatial profile has a diverse pattern of variation over different climatic regions. To comprehend this phenomenon, our study evaluated the spatial scale variation of the Water Quality Index (WQI). The study was carried out over four main climatic classes in Asia based on the Koppen-Geiger climate classification system: tropical, temperate, cold, and arid. The one-dimensional surface water quality model, QUAL2Kw was selected and compared for water quality simulations. Calibration and validation were separately performed for the model predictions over different climate classes. The accuracy of the water quality model was assessed using different statistical analyses. The spatial profile of WQI was calculated using model predictions based on dissolved oxygen (DO), biological oxygen demand (BOD), nitrate (NO3), and pH. The results showed that there is a smaller longitudinal variation of WQI in the cold climatic regions than other regions, which does not change the status of WQI. Streams from arid, temperate, and tropical climatic regions show a decreasing trend of DO with respect to the longitudinal profiles of main river flows. Since this study found that each climate zone has the different impact on DO dynamics such as reaeration rate, reoxygenation, and oxygen solubility. The outcomes obtained in this study are expected to provide the impetus for developing a strategy for the viable improvement of the water environment.

In 2006, the Korean Ministry of Environment established <The 1st Water Environment Management Master Plan>. The plan aimed at “Clean Water, Eco River 2015” and guided water quality protection and strengthened water management. This study evaluated the achievement of the target water quality among the 33 mid-level basins in the Nakdong River basin and assessments of the causes of non-achievement of the target water quality by mid-level basins. According to the 2015 water quality data, only 16 of the 33 mid-level basins achieved the target water quality. The low achievement of the target water quality was attributed to the failure to predict the pollutant load at the time of planning, problems with the management of tributaries, implementation of the <Four major river restoration project>, and problems with the representativeness of the water quality representative points. In addition, feasibility studies on the water quality monitoring representative point used in each mid-level basin were also performed; some mid-level basins required improvement or change of the representative points. This study also suggested further research to improve water quality, such as detailed studies of the management of pollutant load, mainstream tributaries, and water quality indicators, for the revision of the current ongoing <The 2nd Water Environment Management Master Plan>.

Corrosion Properties

Electricity production in Poland is carried out mainly in conventional power plants, and the necessary resources include fuel and water. Significant water intake and production of sewage necessitate the application of technological solutions limiting the negative impact on the water environment. For this reason, Tauron Group's power plants for replenishing losses in cooling circuits use beside surface water, water from inactive mining plants. Due to the increased content of chlorides and sulphates in relation to surface water, mine water show significant corrosion properties. However, they are characterized by a relatively stable chemical composition mainly dependent on the physicochemical properties of the geological environment. The surface water quality is affected by many factors, such as seasons, thaws, rainfall, or the presence of pollutants from sewage disposal. The relative stability of the chemical composition of mine water allows for easier determination of chemical dosage during treatment process. The paper presents a stability assessment of the chemical composition of waters used to supplement circuits based on data from 2007–2017.

The Impact

The visual and odorous characteristics of the environment tend to be those which have the greatest impact upon the public's assessment of environmental quality. In many cases the public's perception of water quality may be based entirely on these aesthetic aspects of a water environment. Those responsible for the management of surface water quality recognise the need to apply a range of management strategies including a consideration of the public's perception of water quality and the impact of this upon their use of rivers and beaches for recreation and amenity. This paper reports upon the results from a recent investigation into the impact of sewage derived litter on perceived water and environmental quality.

Urban Water Quality

In the world scenario the contamination of water due to the various reasons is one of the major problems in the urban and semi-urban areas which have both positive and negative impact on the existed environment and also on the quality of human life. The developing activities taking place in and around the urban areas covers soil with concrete which leads to reduced soil recharge capacity at one side and the other side releasing of untreated urban sewage in to nearby open water bodies without any concern became most practicing method in most of the urban areas. The new capital region of Andhra Pradesh is selected as study area which is rapidly developing with commercial and residential built-up area. Due to which the pressure on groundwater is increased rapidly with respect to its quality and the quantity to meet the requirement of the living as well as migrating people from all the corners to the newly developing capital region. If the similar situation continues there will be a severe and irreparable damage to the availability of groundwater for the future generation and also there will be a notable reduction in the living standards of urban people. The present study examines groundwater and surface water quality and compared with water quality standards to determine the status of water quality at study area. A total three samples were collected for three times in three consecutive months of study period and analyzed by using standard analytical procedures.Geo spatial technology was adopted to represent the statistical data of water quality in the form of GIS maps for more accuracy to identify the periodical changes in water quality at study area

Surface water sources play an important role in human and biological activities and the socio-economic development of the region. Therefore, the assessment of water quality and determination of the causes of water pollution in Sao river is essential for good management of the surface water environment. The study was conducted from July to December 2020. Water samples were collected at the time of low tide to evaluate the water quality indicators of temperature, pH, conductivity (EC), dissolved oxygen (DO), biological oxygen demand (BOD), total suspended solids (TSS), ammonium (N-NH4+), orthophosphate (P-PO43-) and coliform. The source of pollution was determined by direct interviews with households living near Sao river. The results showed that surface water quality in Sao river had signs of organic pollution and microbiological pollution due to BOD, TSS, N-NH4+, P-PO43-, coliform exceeded the allowable limits of National Technical regulation on surface water quality (QCVN 08-MT:2015/BTNMT, column A1). The results of the interview revealed that 70% of respondents said that water was seriously polluted and the main sources of pollution were domestic solid waste and domestic wastewater. Therefore, to improve surface water quality in Sao river, solid waste and wastewater management is urgently required. It is necessary to promote the monitoring and management of water quality with the participation of local authorities and communities.
