Water is essential for all living organisms in the universe. Chemicals can cause contamination in groundwater near aquacultural activity areas. Keeping in view the hectic aquacultural activity in surrounding locations of Akividu town in West Godavari District of AP, India, it is proposed to assess the chemical and microbial contamination of waters to suggest remedial measures to protect the quality of water for safeguarding the health of the public residing in the nearby habitations who consume these waters for drinking purposes. 16 Groundwater samples were collected and analyzed for assessing the physicochemical parameters viz., pH, Electrical conductivity (EC), Total Dissolved solids (TDS), Total hardness (TH), Total Alkalinity (TA), Na+, K+, Calcium, Magnesium, Chloride, Sulphate, Nitrate and Phosphate, Irrigation parameters like %Na, SAR, KR RSC, and microbial analysis. The study results revealed that the samples were contaminated chemically and also with pathogenic bacteria like Pseudomonas, Citrobacter freundii and Escherichia coli which can cause water-borne diseases. Further, a health survey was carried out to verify the adverse effects to be caused by the chemical and microbial contamination of water on people’s health. The health survey results indicated the sufferings of the people who consume this water for drinking and domestic purposes. The waters are to be treated accordingly to control the chemical and bacterial contamination by using the available treatment methodologies before considering them for drinking purposes.

The Bacteriological and physicochemical quality of five (5) boreholes (Ikoyi’s lodge, Newton’s Villa, Iyobosa Hostel, Embassy Hostel and Amega Villa) in Ekosodin village were investigated fortnightly, from March 2004 – July 2004. The bacteriological analysis showed low counts of total heterotrophic and potential human pathogenic bacteria that ranged from 1.0 x 101 cfu/mI – 3.1 x 101 cfu/mI, and 0.0 – 1.9 x 101 cfu/mI respectively. Total coliform counts with MPN values ranged from 0.00MPN/100mI – 9MPN/100mI. E coli occurred occasionally in stations 2, 3 and 5 with a range of 0.00MPN/100mI – 4MPN/100mI. Streptococcus faecalis was observed only in station 3, Clostridium perfringens was not detected in any of the sampled stations. Other organisms isolated and characterized during the study included Staphylococcus aureus and Proteus sp. Some of the physicochemical parameters studied included water temperature, conductivity, pH, total suspended solids, and total dissolved solids. All had low mean concentrations that ranged from 27.0ºC – 28.0ºC; 9.2 – 13.6 us/cm, 6.4 – 6.7; 0.06 – 0.08mg/l and 0.15 – 0.20mg/l respectively. The biological oxygen demand (BOD), dissolved oxygen (DO), total alkalinity and total hardness in mg/l were all low and ranged from 0.08mg/l – 0.2mg/l; 0.7mg/l – 1.0mg/l; 5.0mg/l – 6.0mg/l and 0.10mg/l – 0.13mg/l respectively. Other parameters with low concentration were nitrate (0.05 – 0.11mg/l), sulphate, (0.07mg/l – 0.13mg/l) and phosphate (0.0mg/l – 0.10mg/l). All the physicochemical parameters considered did not indicate any possible physicochemical pollution as they all fell within the (9) maximum permissible level for portable water. There were both positive and negative correlations between some of the bacteriological and physicochemical properties at a significant level of 95% probability limit. Based on the bacteriological and physicochemical parameters studied, boreholes 1 and 4 are fit for direct consumption, while bore holes 2, 3 and 5 failed to meet the bacteriological standard for portable water.

The hydro geochemical features of Neyyar River for a period of one year from May 2015 to April 2016 were analyzed. Six sampling sites were fixed considering physiography and present landuse pattern of the river basin. The residents in the drainage basin are primarily responsible for framing a better landuse and thereby maintain a good water and sediment regime. Geospatial pattern of the present landuse of the study area indicated that the sustainability of this river ecosystem is in danger due to unscientific landuse practices, which is reflected in the river quality as well. The parameters such as hydrogen ion concentration, electrical conductivity, chloride, Biological Oxygen Demand, total hardness and sulphate of river water and Organic Carbon of river bed sediments were analyzed in this study. The overall analysis shows that the highland areas are characterized by better quality of water together with low organic carbon, which is mainly due to better landuse and minimal reclamation. The midland and lowland areas are characterized by poor quality of water with high organic carbon, which is due to high anthropogenic activities and maximum pollutants associated with the region together with the alteration in landuse from a traditional eco-friendly pattern to a severely polluted current pattern.

Quality Of Water

AbstractGroundwater is an important source for drinking water supply in hard rock terrain of Bundelkhand massif particularly in District Mahoba, Uttar Pradesh, India. An attempt has been made in this work to understand the suitability of groundwater for human consumption. The parameters like pH, electrical conductivity, total dissolved solids, alkalinity, total hardness, calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, fluoride, nitrate, copper, manganese, silver, zinc, iron and nickel were analysed to estimate the groundwater quality. The water quality index (WQI) has been applied to categorize the water quality viz: excellent, good, poor, etc. which is quite useful to infer the quality of water to the people and policy makers in the concerned area. The WQI in the study area ranges from 4.75 to 115.93. The overall WQI in the study area indicates that the groundwater is safe and potable except few localized pockets in Charkhari and Jaitpur Blocks. The Hill-Piper Trilinear diagram reveals that the groundwater of the study area falls under Na+-Cl−, mixed Ca2+-Mg2+-Cl− and Ca2+-$${\text{HCO}}_{3}^{ - }$$ HCO 3 - types. The granite-gneiss contains orthoclase feldspar and biotite minerals which after weathering yields bicarbonate and chloride rich groundwater. The correlation matrix has been created and analysed to observe their significant impetus on the assessment of groundwater quality. The current study suggests that the groundwater of the area under deteriorated water quality needs treatment before consumption and also to be protected from the perils of geogenic/anthropogenic contamination.
