The Impact

Due to inappropriate management of vast amount of waste produced by various human activities, urban surface and ground water resources have been under danger of pollution. It is noted that solid waste management is a universal issue and that it is a growing source of worry in developed and developing countries due to the increase in urbanization, changes in consumer pattern, and industrialization which all directly transform to an increase in solid waste generation. The sampling points used of the research are Electronic Waste (e waste) dump sites of Guzape, Karmo and Kubuwa areas of Abuja with terrains of flowing surface water bodies/ pond water. The sample sites were chosen to investigate the impact of e-waste on the water quality of surrounding water bodies in the environment. Parameters measured from collected water samples are pH, Temperature, Conductivity, Turbidity, Dissolved Oxygen, Total Dissolved Solids, Total Suspended Solids, Calcium, Magnesium, Ammonia Nitrogen, Nitrate Nitrogen, Nitrite Nitrogen, Phosphate, Biochemical Oxygen Demand, Chemical Oxygen Demand, Bicarbonate, Manganese, Copper, Zinc, Lead, Cadmium and Chromium. Results showed heavy metal values for Cadmium and Manganese in the water samples were above the maximum permitted level as compared with standards for drinking water, it is inferred that the impact of E waste in the environment contributed to the presence of heavy metals in the water samples. Copper, Zinc, and Chromium were also detected in all water samples collect except for a sample with the absence of Chromium in the water sample.Key words: Disposal sites, Electronic waste, Water quality

Present communication deals with a study of Physico-chemical parameters such as pH, Temperature, Total Suspended Solids, Turbidity, Dissolved Oxygen, Biochemical Oxygen Demand, Nitrate and Phosphate in water samples of Channarayapatna, Janivara, Anekere and Baghur water bodies in Channarayapatna taluka, Karnataka state of India. The water quality of the samples was compared with standard values given by World Health Organization (WHO) and United State Salinity Laboratory for drinking and irrigation purposes. Water Quality Index (WQI) was also calculated to know the overall quality of water samples. Water quality index (WQI) of Surface water body of various Sampling locations of Channarayapatna taluka, Karnataka ranged between 61.82 and 68.27 indicates the fair quality of water. The water quality index is calculated by indicator (100-point scale) shows that water is suitable for drinking purposes only after pretreatment like filtering, boiling, reverse osmosis and electro dialysis. WQI can play a big role in justifying the water pollution problems after encountered in different surface water bodies. Application of Water Quality Index (WQI) in this study has been found useful in assessing the overall quality of water and to get rid of judgment on quality of the surface water.Int J Appl Sci Biotechnol, Vol 4(4): 475-482

The Impact

The impact of partially treated wastewater on the water quality of Notwane river stretch in the Gaborone region of Botswana was investigated. Water samples collected at effluent discharge point and three other sampling sites downstream were analyzed for pH, temperature, Biological Oxygen Demand (BOD5), Ammonia-nitrogen (Ammonia-N) and Nitrate-nitrogen (Nitrate-N). Sampling was conducted bi-weekly between February 2013 and April 2013. The ranges of measured parameters were:  pH (7.6-8.5), temperature (22-23ºC), BOD5 (11.2-27.0 mg/l), Ammonia-N (2.4-60.5 mg/l), Nitrate-N (20.6-28.6 mg/l). Analysis of variance, Games-Howel multiple comparisons and Pearson correlation were used to separate variable means. The results signal river non-point pollution due to runoff inflow of organics mainly from land use and domestic waste dumping by nearby dwellings. Temperature, BOD5, and pH range values were all within the Botswana Bureau of Standards (BOBS) limit while the maximum Ammonia-N and Nitrate-N were above BOBS limit by 50.5 mg/l and 6.6 mg/l, respectively. Regulations on indiscriminate waste dumping and discharge standards adherence should be enforced.

Surface water supplies are gradually becoming short in arid and semi-arid regions of the world. Thus, assessment of groundwater quality for crop use appears to be very essential for management and utilization of precious natural water resources. This study reports the water quality of 52 hand pumps and one tubewell located in the most remote areas of desert region, viz. Islamkot and Mithi talukas of district Tharparkar. The water samples were collected during April 2016 (just before the start of rainy season). The water samples were analyzed for EC (Electrical Conductivity), pH, CO32-, HCO3-, Cl-, Ca2+, Mg2+ and Na+ concentration. The SAR (Sodium Adsorption Ratio) and RSC (Residual Sodium Carbonates) were estimated using their respective formula. The categorization of water samples based on their soluble salt content clearly revealed that the water bodies of majority (65%) of areas were hazardous, while 25% areas were marginal. Thus, only 11% water samples of the area under study had useable irrigation water. Because of SAR and RSC the majority (89 and 77%, respectively) of water samples were found to be free from the sodicity hazard. The study concluded that salinity, and not sodicity was the major threat to the area under irrigation with these water bodies. It is, therefore, suggested that the salinity tolerant crops and their genotypes may be used in this area to sustain crop production.

Thermotolerant Coliforms

In Brazil, about 49% of the population does not have access to the sewage collection network, with the consequent direct discharge of their sewage network into water bodies. Due to this scenario, it is essential to investigate the quality of the water consumed by thousands of people along the Negro and Resende Rivers. The present study analysis the waters of the Negro and Resende rivers, located in Dois Rios River Basin, in the municipality of Duas Barras, Rio de Janeiro State (RJ, SE Brazil), based on the Water Quality Index proposed by the National Sanitation Foundation (United States). The population of the district located in the municipality of Duas Barras dumps the domestic sewage directly into the hydrographic network. The analyzed parameters were: turbidity, total solid residue, total phosphorus, total nitrogen, biochemical oxygen demand (BOD), hydrogenation potential, temperature, dissolved oxygen and thermotolerant coliforms. The values obtained from the calculation of the Water Quality Index (WQI) showed a variation from 40 to 68, meaning that the quality of water vary between bad and acceptable in the study area. The samples collected in the urban area contained values for thermotolerant coliforms in disagreement with the maximum value permissible for classes 2 and 3 of fresh water by CONAMA (Conselho Nacional do Meio Ambiente; a Brazilian Council for the Environment) Resolution 357/2005. The results of the analyzes confirmed the contamination of the two rivers by the discharge of domestic effluents, showing that actions are necessary to eliminate or minimize the discharge of sewage in the surveyed water bodies, since it may cause public health risks. ResumoNo Brasil, cerca de 49% da população não possui acesso à rede de coleta de esgoto, com o consequente despejo direto da sua rede de esgotos em corpos hídricos. Diante deste cenário, torna-se indispensável investigar a qualidade da água consumida por milhares de pessoas ao longo dos rios Negro e Resende. A presente pesquisa analisou qualitativamente as águas dos rios Negro e Resende, localizados na Bacia Hidrográfica do Rio Dois Rios, no município de Duas Barras/RJ, a partir do índice de qualidade das águas proposto pela National Sanitation Foundation. A população do distrito sede do município de Duas Barras despeja o esgoto doméstico diretamente na referida rede hidrográfica. Os parâmetros analisados foram: turbidez, resíduo sólido total, fósforo total, nitrogênio total, demanda bioquímica de oxigênio, potencial hidrogêniônico, temperatura, oxigênio dissolvido e coliformes termotolerantes. Os valores obtidos no cálculo do índice de qualidade das águas (IQA) mostraram uma variação de 40 a 68, significando uma qualidade da água entre ruim e razoável. As amostras coletadas na área urbana apresentaram valores para coliformes termotolerantes em desacordo com o valor máximo permitido para classes 2 e 3 de água doce, regulamentados pela Resolução CONAMA 357/2005. O resultado das análises confirmou a contaminação dos dois rios pelo lançamento de efluentes domésticos, os quais poderão originar riscos de saúde pública. Os resultado evidenciam a necessidade de se desenvolverem ações para eliminar ou minimizar os despejos de esgotos nos referidos corpos hídricos.

Quality Status

The issues of freshwater pollutions and the high demand of clean freshwater for daily human activities have forced developing countries such as Malaysia to continuously monitor the quality of the freshwater. The present study objective is to present the trend of water quality status in the Kelantan River downstream, Peninsular Malaysia from 2005 to 2018. Water samples were collected during dry and monsoon seasons from a sampling station located at downstream of the Kelantan River. Water quality parameters such as temperature, pH and dissolved oxygen (DO) were measured in situ while other parameters were analysed in the laboratory based on retrieved water samples. Water quality status was determined based on National Water Quality Standard (NWQS) for River in Malaysia by calculating the water quality index (WQI) according to the concentration of six water quality parameters involving pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (TSS) and Ammonia Nitrogen (AN). The results showed that Kelantan River had good water quality during the dry season classified in Class II at 2005. The water quality was found to be slightly lower during the monsoon season in year 2006. In addition, increasing the number of construction, human activities in the land use areas, land use changes and the sewage water from domestic, industrial, wet market and food outlets in the Kelantan State have declined the water quality in Kelantan River from Class II (in 2005) to Class III (in 2010 and 2011) and to become Class IV in 2017 to 2018. The results of the present study are expected to give valuable information for the water managers in order to deal with better strategies in controlling the quality of freshwater at the Kelantan River and minimize the incidence of pollution-oriented problems, thus the water can be utilized for various water uses with appropriate quality.

The impact of land use on the water quality of foothill microcatchment areas The impact of land use on the water quality of foothill microcatchment areas. In this paper a comparison is made between the impact of land use methods on the quality of water in the streams which drain various catchment areas. For this purpose three microcatchments were selected which are located in agricultural, rural settlements, and forested areas. Water samples were physically and chemically analysed in order to determine: nitrates, nitrites, ammonia, phosphates, sulphates, chlorides, calcium, magnesium, dissolved oxygen, reaction and conductivity. The above studies were conducted in the 2006 and 2007. Our analysis of the collected materials allows us to affirm that land use methods have a significant impact on the water quality of the streams which drain the area. Rural settlement has the most negative influence on the water quality, followed by typical agricultural use. Based on the direct quality evaluations of single water samples, it has been found that only water from forested areas can be qualified as belonging to the 1st cleanness class.

Purpose: to assess the quality of water in water bodies of the Volga-Akhtuba floodplain from an ecological viewpoint, taking into account the modern regulatory framework in the field of environmental protection. Materials and Methods. To assess the quality of natural waters from an ecological viewpoint, a complex indicator calculated by basic analyte markers that characterize typical negative impacts was used. The following hydrochemical indicators were taken as analyte markers: pH, mineralization (dry residue), suspended solids of natural origin, total iron, total manganese, ammonium (N), nitrites (N), nitrates (N), phosphates (PO4), chemical oxygen demand (COD). Results. The ecological state of water bodies was determined by hydro-chemical indicators of surface waters and bottom sediments using the example of such representative objects as water bodies on the territory of the Volga-Akhtuba floodplain: lakes Peschanoe, Varyuzhka, Zhestkovo, erik Chayka, lakes Beshenoe, Chubatoe, Yamy, erik Shumrovatyy, lake Shirokogorloe. In accordance with the provisions of GOST R 58556-2019 “Assessment of water quality in water bodies from an ecological point of view”, the quality of water from an ecological viewpoint, the degree of quality disturbance and changes in the state of aquatic ecosystems under anthropogenic load have been determined. Conclusions. Petroleum products have been recorded in the water bodies of the Volga-Akhtuba floodplain (lake Varyuzhka, erik Shumrovatyy). The analysis of hydrochemical indicators of water quality and bottom sediments shows that currently the overall level of pollution of the considered water bodies does not reach critical levels of permissible values.

The Impact

The aim of this work was to examine the impact of urban wastewaters on the water quality of the Danube River in Serbia. Samples of water and sediments for microbiological analysis and genotoxicity monitoring were collected from 6 sites during spring and/or autumn 2010. Sanitary analysis, i.e. enumeration of total and fecal coliforms and intestinal enterococci, indicated moderate to critical fecal contamination, while organic load assessment (oligotroph to heterotroph ratio, index of phosphatase activity) revealed the category of moderately polluted water. Mercury-resistant bacteria were detected in all water samples, with high numbers at locations positioned downstream of Belgrade. There was no correlation of the microbiological parameters of the sediment and water samples. Genotoxicity monitoring, performed by the comet assay on hemocytes of mussels Sinanodonta woodiana, indicated a significant increase of DNA damage in mussels collected from the studied sites compared with the control group.
