In the present study analysed Groundwater quality of Hard rock terrain in Bengaluru North, Karnataka, India. For the present study areas affected by industrialization were selected to measure the quality of Groundwater for determining its fitness for domestic use. Bore well samples from each part of the study area were analysed for Physio - chemical variations and quality of groundwater. Comparison of Physio - chemical analysis results with Indian Standard drinking water limits shows that all groundwater samples except few are fit for drinking and irrigation purposes. The average value of pH of five villages is 7.5-8.0 which is within desired limit. However, the pH value is increasing so it may be unfit for the future use. About 50% of Water samples containing chloride in excess of 250mg/l are considered undesirable for drinking purposes which may lead to cardiovascular diseases. The concentration of sulphate for each sample of villages is within desirable limit. Also it is found that 25% of samples containing total hardness more than 300 mg/l which is undesirable. In future there may be threat of decrease in groundwater quality. Public awareness must be created among the citizens about the importance of lakes/tanks and give awareness about importance of quality of Groundwater and surface water.

A detail understanding of the hydrogeochemical characteristics and groundwater quality is indispensable for the sustainable utilization of the groundwater sources. This is in line with sustainable development goal of United Nation. The following parameters were analyzed using APHA, 2012 standard: pH, Ec, total dissolved solid (TDS,) total hardness (TH), magnesium (Mg2+), sulphate (SO4 2¯), chloride (Cl¯), bicarbonate (HCO3¯), carbonate (CO3 2¯), nitrate (NO3¯), potassium (K+), sodium (Na2+)and calcium (Ca2+). Findings revealed that pH value reveals that groundwater is acidic. Bivariate plots showed that groundwater quality is influenced by number of factors. Hydrogeochemical assessment of groundwater samples was based on the following model:End-member, Parson’s and Diamond field plots. Results from these plots revealed that silicate and carbonate weathering are the major factors that control groundwater quality and that groundwater samples were of different water type namely, Ca–Mg–SO4, Ca–Mg–Cl, Na–SO4 water type and high Ca+Mg & SO4+Cl respectively. It was observed that 99 % of groundwater within the study area fell within fresh water category and groundwater is influenced by various factors. Bangladesh J. Sci. Ind. Res.55(4), 245-252, 2020

Abstract The Udham Singh Nagar district is affluent in fertile land, water resources, and even favoured for industrial advancement, thereby resulting in a rapid increase of industrialization and urban growth, which are the inevitable causes for groundwater contamination. During recent years the increased rate of urbanization and the establishment of Integrated Industrial Estate (IIE) at Pantnagar, Kashipur and Sitarganj area (of the district) have increased the demand for groundwater. A proper groundwater resource planning and monitoring on a regional scale is required to cope with the pace of rapid urbanization and industrialization along with dire irrigation needs. To suffice this strategy, the spatial distribution of water quality shall determine the kind of sustainable approach to be implemented in an area. The objective of this research is to assess the hydrochemical quality of the groundwater in Udham Singh Nagar district (areal extent 3055 Km2), Uttarakhand. The groundwater samples collected from the aquifer have shown anomalous values of Total Hardness (TH), Total Dissolved Solids (TDS), Magnesium (Mg2+), Iron (Fe2+), and Lead (Pb2+) on undergoing major elemental analysis which confirms about degradation in the groundwater quality. Moreover, the Piper Trilinear Diagram (PTD) has identified the hydrochemical facies, and characterization of groundwater. Based on the interpretation of TDS, most groundwater samples <500 mg/l dissolved solids, making it desirable for drinking. Therefore, this phenomenon attributes to suitable drinking water present in the aquifer of Udham Singh Nagar district, Uttarakhand.

This paper presents a geospatial analysis of the groundwater quality of Ludhiana, Punjab, India. The groundwater samples were collected from 99 locations using grid based sampling procedure and analysed for parameters viz. pH, total dissolved solids (TDS), total hardness (TH), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), fluoride (F-), chloride (Cl-), nitrate (NO3-), sulphate (SO24-) and bicarbonate (HCO3-). Sampling was done during both pre-monsoon and post-monsoon periods. Water quality index (WQI) was used to represent the groundwater quality of the study area. The WQI coupled with the spatial maps indicated that merely (1%) of the total study area had good groundwater quality and the rest of the study area fell under poor, very poor and unsuitable for drinking purpose. The geographical information system (GIS) based groundwater quality mapping presented in this paper could be a potential tool for groundwater quality management.

The water quality of Hengshui Lake in different regions and at different times was analyzed. According to the data analysis results of chemical oxygen demand (COD), biochemical oxygen demand (BOD5), ammonia nitrogen (NH3-N), total nitrogen (TN), total organic carbon (TOC), total phosphorus (TP), calcium ion content, total hardness, chloride ion content, pH value and conductivity of Hengshui Lake water samples, the water quality of Hengshui Lake was evaluated and analyzed. The results showed that the pollution of Hengshui Lake was mainly organic matter pollution, especially non-biodegradable organic matter pollution. The value of TN was higher than the Class III water, which showed that the self purification capacity of Hengshui Lake water body was weaker. The water quality of Hengshui Lake was better, but the treatment of organic pollution should be paid attention to.

AbstractRampant use of groundwater for drinking purposes in several parts of the world has raised the concern over its quality. Owing to increasing population, overuse, and pollution of surface water sources, the use of groundwater has increased to considerable extent. Despite this, little attention is paid towards the monitoring of groundwater resources to assess their suitability for drinking purposes. To assess the groundwater quality in rural areas of Ujjain District of Madhya Pradesh, India, in order to check its suitability for drinking purpose, water quality analysis was done at seven time points during the two study years in six villages of Ujjain District, Central India. A total of 868 groundwater samples from 124 households were collected, and standard analytical methods were employed for analysis. Overall groundwater quality of the area is good and qualified for drinking. However, occurrence of high amount of dissolved solids (> 800 mg/L) and hardness (> 400 mg/L) is the issue of concern, as long-term use of such water might result in variety of health ailments, such as kidney stones and atopic dermatitis in children. Regular monitoring and long-term surveillance of drinking water sources are necessary to keep track of the changes occurring in the system.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

Groundwater samples were collected in Erode city, Tamilnadu, from an area having large number of textile dyeing units. Though people residing in this area use river water supplied by local bodies as their major source for drinking, groundwater is also used as complementary source. The samples collected were subjected to systematic analysis using the standard methods and procedures. The values obtained for different physicochemical parameters were compared with the standard values given by ISI/ WHO. Variations in many physicochemical parameters were observed for most of the samples when compared to the standard values. More than half of the samples collected had their EC, TDS, total hardness, calcium, magnesium, sulphate and chloride exceeding their acceptable limits. This attempt has been made to determine the quality of groundwater in the study area confirms the deterioration of groundwater quality in the area and calls for some effective measures to be taken urgently to minimize the adverse impacts that may occur due to the contamination of groundwater.
