AbstractThe aim of this study is to evaluate the hydrogeochemical characteristics and water environmental quality of shallow groundwater in the Suxian mining area of Huaibei coalfield, China. The natural formation process of shallow groundwater in Suxian is explored using Piper trilinear charts and Gibbs diagrams, and by examining the ratios between the major ions. United States Salinity Laboratory (USSL) charts, Wilcox diagrams, and the water quality index (WQI) are further employed to quantify the differences in water quality. The results reveal that the main hydrochemical facies of groundwater are HCO3–Ca, and that silicate dissolution is the main factor controlling the ion content in shallow groundwater. The USSL charts and Wilcox diagrams show that most of the water samples would be acceptable for use in irrigation systems. The WQI results for each water sample are compared and analyzed, and the quality of groundwater samples around collapse ponds is found to be relatively poor.

Drinking Purposes

The study focuses on the quality of shallow groundwater in Bulgaria based on the content of major ions. To be safe for drinking purposes, their concentrations must not exceed the respective thresholds. The groundwater quality is assessed in terms of health hazard by a groundwater quality index (GWQI or WQI), and the respective map is presented. The results show that for the territory of Bulgaria, this index varies from 13 to 92. The highest values of this index (related to health hazard) are typical for the lower hypsometric zone of the country. The shallow groundwater in the zone of active water exchange is distributed as follows: waters of excellent quality, waters of good quality, waters of poor quality, and waters of very poor quality, covering 3%, 39%, 22%, and 31% of the whole area of the country, respectively. In this study, no estimates have been made for 5% of the territory of Bulgaria, which is characterized by the presence of very hard groundwater.

Abstract The aim of the study was to assess the quality of shallow groundwater on the site pens and runoff from livestock manure heaps, in three selected farms involved in animal production and vegetable crops in the area of Plateau Proszowice. The analysis mainly included water from farm wells and effluents from manure. Additionally, water from drainage ditch running nearby farms was collected, before inflow of effluent (i.e. ditch water without manure effluent) and below inflow of effluent from heap of manure (i.e. ditch water containing manure effluent). Samples of the research material were collected from April 2012 to March 2014 at monthly intervals and analysed for the content of NO3-N, NH4-N, PO4-P, K, Na and Cl. Based on the obtained results it was found that water from the farm wells near the livestock buildings and from manure storage sites, was heavily polluted by the majority of these contaminants. The highest concentration of these pollutants, except for the NO3-N, was found in manure effluent – it exceeded a few dozen to a few hundred to any standards for water quality. There was also a significant deterioration in the quality of drainage ditch water because of the penetration of contaminants into ditch water from heaps of improperly stored manure. The water of the farm wells was characterized by excessive concentrations of NO3-N which disqualified it for drinking purposes.

AbstrakSungai Klampok mengalir melalui Kecamatan Bergas dan sekelilingnya terdapat beberapa industri sehingga mengakibatkan sungai tersebut tercemar karena menjadi badan penerima air limbah. Akibat penurunan kualitas air Sungai Klampok akan berimbas pada penurunan kualitas air tanah yang digunakan oleh penduduk sekitar sungai tersebut. Penelitian ini bertujuan untuk mengetahui kualitas air tanah yang berada di sekitar Sungai Klampok sebagai akibat adanya pengaruh beban pencemaran oleh air limbah industri berdasarkan Permenkes No. 416/MENKES/PER/IX/1990 tentang persyaratan kualitas air bersih. Lokasi pengambilan sampel air sungai dibagi menjadi 3 stasiun (LK1, LK2 dan LK3) sedangkan untuk sampel airtanah dari rumah-rumah penduduk dilakukan pada 6 titik yaitu 3 titik di daerah utara dari Sungai Klampok (U1,U2, U3) dan 3 titik di daerah selatan dari Sungai Klampok (S1,S2, S3). Pengambilan sampel dilakukan pada musim kemarau. Dari hasil uji kualitas air sungai, pencemaran yang terjadi pada air sungai Klampok masuk dalam kategori tercemar ringan-sedang. Sedangkan hasil uji kualitas air tanah masih berada di bawah baku mutu yang disyaratkan oleh Permenkes No. 416/MENKES/PER/IX/1990, sehingga penurunan kualitas air sungai Klampok tidak mempengaruhi kualitas air tanah di sekitar sungai tersebut. AbstractThe Klampok River flows through the Bergas Subdistrict and there are a number of industries around it, causing the river to become polluted because it becomes the body of the recipient of wastewater. As a result of the decline in the quality of the water in the Klampok River, it will impact on the quality of groundwater used by residents around the river. This study aims to determine the quality of groundwater around the Klampok River as a result of the influence of pollution load by industrial wastewater based on Permenkes No. 416 / MENKES / PER / IX / 1990 concerning requirements for clean water quality. The location of river water sampling is divided into 3 stations (LK1, LK2, and LK3) while for groundwater samples from residential houses is carried out at 6 points, namely 3 points in the northern area of Klampok River (U1, U2, U3) and 3 points in the area south of the Klampok River (S1, S2, S3). Sampling is done in the dry season. From the results of the test of river water quality, pollution that occurs in Klampok river water is categorized as mild-moderate polluted. While the results of groundwater quality testing are still below the quality standards required by Permenkes No. 416 / MENKES / PER / IX / 1990 so that the decline in the water quality of the Klampok river does not affect the quality of groundwater around the river.

AbstractThe study examines the water quality of Shahdadkot, Qubo Saeed Khan and Sijawal Junejo talukas of Qambar Shahdadkot District, less affected by industrial contamination. A total of 38 groundwater samples were collected and analysed for 28 parameters. The results indicated that 57.89% samples were not suitable for drinking purpose with total dissolved solids above than maximum permissible limit of World Health Organization (WHO) (1000 mg/L). The pH, total phosphate, orthophosphate and nitrite were within WHO limits. The concentration of essential metals more than half samples, fluoride in 60.52% and heavy metals 0–50% were contaminated higher than permissible limits of WHO. The statistical analysis of water quality parameters was also carried out to evaluate coefficient of determination among the parameters, cluster analysis and principal component analysis. Water quality determined for irrigation based on Kelly index (KI), sodium percentage (Na%), chloride–sulphate ratio, sodium adsorption ratio, permeability index (PI), chloroalkaline indices 1 (CAI-1), residual sodium carbonate and chloride bicarbonate ratio indicated that samples (55 to 100%) could be used for irrigation purposes. The consumption of water with high concentration of salts and fluoride above the permissible limits may be a cause of a number of diseases in the area.

Abstract Major ion and trace element concentrations in shallow groundwater of Linhuan coal-mining district, Northern Anhui Province, China, were analyzed to determine its hydrogeochemical characteristics and to assess drinking and irrigation water quality. The relative abundance of cations and anions was Na+ > Mg2+ > Ca2+ > K+, and HCO3− > SO42− > Cl− > NO3−, respectively. The concentrations of Na+, HCO3−, NO3−, and total dissolved solids (TDS), and the electric conductivity (EC) values in some samples were higher than the permissible limits of the Water Health Organization (WHO). Gibbs diagrams showed that rock weathering mainly controlled the major ion chemistry of the groundwater, and the first aquifer of this study area had a weak hydraulic connection with atmospheric precipitation. The calculated sodium percentage (%Na) and sodium adsorption ratio (SAR) revealed that the slight sodium and high salinity hazards needed to be controlled before irrigation. According to the fuzzy comprehensive assessment, the groundwater samples were classified into four categories. The results showed that 92.86% of the groundwater samples were suitable for drinking use. For human health, the NO3− and Mn levels in the groundwater should be reduced before drinking, and treatment of the high salinity hazards is required before irrigation.

Research has been conducted to determine the quality of shallow groundwater (dug-wells and shallow bore-wells) and the local communities opinions around the landfill Suwung. The method of determining the station was done by purposive sampling, where the station sampling was determined by selecting a place which was expected to represent the whole area.Water sampling of dug-wells was conducted by using a water sampler and the shallow bore-wells using a 2-liter bottle. Data was analyzed by descriptive comparative referenceto class I water quality of the Bali Governor Regulation No.8 of 2007. The public opinion data was obtained by using aquesioner filled by respondents who have and use wells and shallow bore wells for their daily needsand it was analyzed by using frequency distribution tables.The results showed that the quality of shallow groundwater (dug-wells and shallow bore-wells) did not meet water quality standards in accordance with the rules of the class defined in the Governor of Bali Regulation No. 8 of 2007. The water pollution index (PI) of dug-wells at a distance of 1-400 meters was in hearily polluted category, while water fromshallow bore-wells drilled at a distance of 1-200 meters was in the category of hearily polluted and at a distance of 201-400 meters was in the category of medium polluted.There was an increasing range of groundwater quality deterioration in 1997, 2008 and 2014. In 1997, contaminated shallow groundwater has occured at a distance of 80 meters, while in 2008, the pollution has occurred up to a distance of 375 meters and in the year of 2014 the contamination occurred from a distance of 1 meter to 400 meters. The average of score Pollution Index (PI) of Water wells in the year of 2008 amounted to 14.55, while in 2014 up to 15.44. It is estimated that the water quality of dug-wells and bore-wells will meet the quality standards in accordance with the value of the pollution index at a distance of over 5000 meters and 750 meters of the Suwung landfill waste.Most of the respondents who live in the vicinity Suwung landfill waste tend to give an opinion that the shallow groundwater (dug-wells and shallow bore-wells) has decreased quality as drinking water. Approximately 75% of respondents thought that the well water in their environment has been reduced in quality.

According to many uncertain problems of current water quality comprehensive assessment, a Bayesian model for water quality evaluation was established based on the basic principles of Bayesian formula. Select monthly monitoring data for 5 parameters at 15 different monitoring sections, generated from July 2006 to June 2007 and use Chinese GB3838-2002 as evaluation standards to analyze the water quality grade in this study. The annual evaluation results show that the water quality of ChangLe River mainly belongs to Ⅲ and Ⅳ grade. The monthly water quality has a certain relation with rainfall. The Bayesian method has the characteristic of more integrated, suitable for both large and small samples, simple calculation and easily to be used widely.
