Subject: Seasonal Effect On Physico-Chemical Parameters Of Water Quality And Correlation Analysis Of Heavy Metals at Nawabganj Lake
Keywords: Anthropogenic pollution, Environment stress, Heavy metals, Nawabganj lake, Nutrients
Abstract: Nawabganj lake water has the supplementation through irrigation canal systems in the area. This very effective management method is a necessity and becoming increasingly popular in conserving the lake environments in urban areas. This small lake, spread in an area of 2.25 km2, attracts hundreds of migratory bird species during winters. But presently, water contamination of the lake is a main cause of concern. Nawabganj lake is one of the most important and among the endangered, environmental resources. The lake or surface water bodies has been polluted due to stagnant nature and numerous anthropogenic activities (irrigation, agriculture, construction activities, clearing of land and domestic waste disposal) around them. Due to pollution the quality and quantity of utilizable lake water decreases which ultimately results in the water crisis. It is important, to identify the pollution sources and development of water quality. Thus the lake is subjected to enormous anthropogenic stress and the overall impacts have resulted in the deterioration of the water quality, accumulation of nutrient and toxic heavy metals of water, plants and sediments, shrinkage of the lake area and above all, loss of the aesthetic value and causes environmental stress.

Keywords: UNESCO world heritage site, Noise pollution, Leq, Sound level meter, CPCB standards
Abstract: This paper is based on a study related to measurement of ambient noise levels at the UNESCO world heritage city Jaipur. The equivalent continuous sound level (Leq) is calculated for the morning and evening peak hours using noise levels measured with a sound level meter. The study has been conducted during January to March 2020 and the sampling locations consisted of major tourist spots, famous markets and the large gates constructed at the time of establishment of the old historic walled city. The time interval of peak hours was chosen from 0800-1100 hr in the morning and 1700-2000 hr in the evening. The noise levels were recorded at all the 15 sampling locations and compared with the permissible limits/standards prescribed by the Central Pollution Control Board (CPCB) of India under the Noise Pollution (Regulation and Control) Rules, 2000. It has been found that all the results are beyond the prescribed limits as per CPCB, which is a very serious issue looking to the UNESCO world heritage site status recently awarded to Jaipur city. It is the duty of all concerned stakeholders including govt. authorities, businessmen, non-govt. organizations and general public to uphold the status of UNESCO world heritage city in its truthful manner.

Subject: Water Quality Indices – A Comparative Review
Keywords: Water, Quality index, Effluent, Drinking, Pollution
Abstract: Water pollution is one of the major challenges in front of human civilization. Scarcity of drinkable water is raising its highest peak. Observing the alarming situation, United Nations declared access to drinkable water as a fundamental right of every world citizen [1]. This situation excels the research in water quality, water characterization and water treatment. Not only the anthropogenic sources are causing water pollution but also the natural sources are polluting water. Thus many of the lakes and seas are polluted by natural sources and thus does not provide drinkable water. Considering this, researchers are concentrated on characterizing the water quality, depending on its suitability to drink or dispose of to a certain source. Drinkable water standards are established based on human health requirements, whereas, effluent water standards are established based on the ecology of the water body on which the effluent waters are being discharged. This paper reports a review of the water quality indices (WQIs) developed by different researchers and their comparative evaluation for some case studies.

Keywords: Industry, Adsorption kinetics, Phenol, Charcoal, Local charcoal, Activated carbon
Abstract: The research of the adsorption kinetics of phenol in aqueous solution was studied by measuring the concentrations of remaining phenol in the solution as a function of time (t) and the parameters of the operating temperature (T), the particle diameter of activated carbon (d) and the ratio of the mass of the adsorbent to the mass solution (r). This research used the adsorption method by using local charcoal activated carbon products. The study was conducted by measuring the adsorption velocity (the ratio between the concentration of adsorbent before and after the adsorption operation took place) as a function of time, by varying the operating temperature, grain size, and the ratio of the mass of the adsorbent per mass of solution. In this research, the method used to evaluate constants value in the empirical rate expression is the graphical method. The results of the research show this adsorption method is one way of handling the waste which is quite easy and economical.

Abstract: The study was carried out to analyze the heavy metal contamination in the groundwater of Tirunelveli district, Tamil Nadu. To get the extend of heavy metals contamination, water samples were collected from eleven different locations in the study area and the concentrations of heavy metals, such as iron, zinc, copper, lead and cadmium were determined using atomic absorption spectrophotometer (AAS). It is a well known fact that the heavy metal ions are potentially toxic to human health and could be quite detrimental for human life. Groundwater contamination by heavy metal was carried out using contamination factor, contamination degree, modified contamination degree, pollution load index, metal contamination index, enrichment factor and metal pollution index. Based on the above indices, it is shown that all heavy metals are present within the permissible limit and the study area is found to show very low degree of heavy metal pollution. It indicates the metals are entirely from crustal materials or natural processes.

Subject: Assessment Of The Effect Of Monsoon In Gagan River Water Pollution
Keywords: Parameters, Index, Quality rating
Abstract: Drinking water pollution causes health problems which can be prevented by taking appropriate actions. Water quality index (WQI) is effective way to communicate and parameterize quality of water. The data obtained through quantitative analysis of water is measured up against WHO water quality standards to calculate water quality indices. The purpose is to assess river water pollution and effect of monsoon at Moradabad (Uttar Pradesh). Water quality index (WQI) for Gagan river water at thirteen different sites at Moradabad has been calculated for pre-monsoon period and after onset of monsoon with the help of estimated values of seventeen different physico-chemical parameters and WHO water quality standards. River was polluted at all the sites that were studied for both periods. At almost all the river water sites, the water quality shows some improvement after the onset of monsoon, however, river water was still severely polluted. Higher estimated values of various parameters on the basis of water quality indices also support and verify the results of river water pollution. Mixing up different effluents with river water multiplies the river water pollution. People that are exposed to such severely polluted water are threatened and water quality management is imperative in the catchment area of study.

Abstract: Electrical resistivity survey was carried out in Masgerdo river basin, Borena, southern Ethiopia, in order to assess the groundwater potential zones. Geologically, study area is underlain by volcanic basalt rocks, quaternary deposition and precambrian granitic basement rocks. 20 vertical electrical soundings were carried out with Schlumberger electrode configuration with current electrode spacing (AB/2) half ranging from 1-750 m. The measured apparent resistivity signals have been interpreted through curve matching technique using IX 1D software. The curves are prominently of QH, KH and HA type indicating the presence of 4 layers followed by a combination of curves QKA, KHK, KQH, QQH, QHK, QKK, HKH, QQQ and QHA indicating the presence of 5 sub-surface layers. Interpretations of resistivity data reveal the number of sub-surface layers, thickness and groundwater bearing capacity within the study area. The best layer which acts as the good groundwater aquifer of study area is the 3rd and 4th layer which consists of medium to highly weathered/fractured rock and unconsolidated sand formations at the depth between 4-20 m.

Abstract: Life on earth is chiefly dependent on water, hence the quality of water is a big concern for healthy life. Population explosion, urbanization and industrialization are affecting the water resources quite badly and it is important to assess this quality at regular intervals. The current study is focused on evaluation of water quality of the Ranjit Sagar dam reservoir using water quality index (WQI) and heavy metal pollution index (HPI) method. This provides a single numerical value from a diverse set of water quality parameters. Water quality index in the study period varied from 23.98-140.3 and heavy metal pollution index (HPI) varied between 212.99-822.33. The evaluation of variation among seasons and sites is interpreted by the application of one as well as two-way analysis of variance and paired t-test. The successful use of these indices for assessing ecosystem health is being proposed through the study.

Keywords: Coastal tourism, Developmental planning, Ecosystem services and functions, Corporate sector, Public-private partnerships, Sustainable development
Abstract: Growing coastal tourism and undesired developmental planning along the Maharashtra coastline has been a serious concern lately. Coastal tourism along the Malvan coast, especially to the south of Malvan in Tarkarli and Devbag villages has picked up in the 21st century. Tarkarli and Devbag villages are the two different administrative units in the region which are originally the part of Tarkali-Devbag spit, a homogeneous geomorphic feature. However, with burgeoning tourism and an unsustainable vision, ecosystem services and their functions are being undesirably exploited on the spit. Karli creek, which forms the eastern boundary of this spit is being used for tourism for more than two decades and is in a dire need of a creek management strategy. To counter these issues, local panchayats need to have policies and action plans for sustainable beach tourism, groundwater management and coastal protection. Therefore, the authors, through their recent fieldwork in the study area which includes interviewing locals and authorities and taking field measurements, would like to share their knowledge and bring forward the serious points of concern; especially regarding the policy frameworks and action plans. They would also like to express their stand on how the corporate sector through public-private partnerships (PPP) can help in the sustainable development (SD) of the region.

Abstract: At the global outlook, providing potable water is hour of the need. The research engrossed in synthesis and evaluation of a novel nanocomposite clay filter with a keen focus on disinfection properties. Composition and volume of the clay filter were predetermined. An inlet of 105 E. coli cells was traversed via clay filter in batch and continuous mode at varied flow rates. Results revealed that in batch mode zero cell count was achieved in 20 min where as, in continuous mode within 15 min at flow rate 20 mL/min. The disruption and disparity of E. coli cells after traversing through the clay discs were confirmed by SEM technique. Rupture of the bacterial cell wall might be due to imbalance of structural morphology exerted by the positive charge of nanocomposite clay filter on the negative charge of bacterial cell wall. The research ended up with a net result that can be glorified and expanded in future.

Abstract: The concrete structures normally have some capacity for self-healing, which means the concrete can able to seal or heal freshly formed micro-cracks which property mainly because of an excess of non-hydrated cement particles present in the materials. This reaction with ingress water undergoes secondary reaction. This paper carried out a new kind of self-healing concrete by using bacteria as mediate production of minerals which can seal the freshly formed cracks rapidly. The characteristics of self-healing bacterial concrete with M-sand and various dosages of Bacillus substilis, like 0 mL, 10 mL, 20 mL and 30 mL for the M25 grade concrete, in its fresh state are investigated by workability, while hardened characteristics are investigated by compressive, tensile strength, durability studies of acid test, like hydrochloric attack, sulphate attack and chloride attack and self-healing assessment. The study was carried out on fresh and hardened characteristics of a bacteria based self-healing concrete with M-sand using Bacillus subtilis bacteria. The test results indicated that by the addition of 20 mL amount of bacterial content in self-healing concrete with M-sand, the characteristics of durability performance was greatly altered and thus facilitate a sustainable environment.

Subject: Optimization Of Hexavalent Chromium Ion Removal From Electroplating Wastewater Onto CMAC Using Factorial Experimental Design Analysis
Keywords: Cucumis melo peel activated carbon, adsorption capacity, Factorial design
Abstract: Factorial experimental design technique (FED) was used to investigate the adsorption of hexavalent chromium ion [Cr(VI)] from wastewater onto Cucumis melo peel activated carbon (CMAC). The structural and morphological features of activated carbon are characterized by FTIR and SEM studies. Physico-chemical characteristics and adsorption efficiency of CMAC of the wastewater are also being determined. Batch experiments are carried out for the adsorption of metal ion onto CMAC by the parameters, such as pH (3-9), adsorbent dosage (50-250 mg), concentration of metal ions (100-400 mg/L) of the adsorption capacity. The factorial design (23) is used for the interactions between three process parameters for the adsorption of metal ion is evaluated. The results of adsorption are subjected to statistical analysis by using the t-test, ANOVA, F-test which confirms the fitness of adsorption. To optimize and to know the maximum efficiency, the experimental data are used to obtain the normal probability plots, main effect; interaction plots, Pareto charts and contour plots by using design of experiment software with revelation of the best fitness. The results revealed that CMAC as a potential adsorbent for the adsorption of heavy metal ion [Cr(VI)].

Subject: Aquifer Characterization And Identification Of Groundwater–Surface Water Interaction In Hard Rock Region Using Electrical Resistivity Method
Keywords: Vertical electrical sounding, Electrical resistivity, Surface water and groundwater interaction, Groundwater delineation, Hard rock region
Abstract: Extensive pumping of groundwater resources in an agricultural field leads to groundwater depletion in terms of both quantity and quality. In this study, electrical resistivity investigations were carried out to identify the groundwater potential zones, assess the impact of agricultural practices on groundwater quality and evaluate the interaction between pond and aquifer. A total of 13 vertical electrical sounding (VES) were carried out near wells and ponds in the agricultural field. Based on the rock resistivity variations, characteristics of the sub-surface layer and its thickness were determined. The parameters, such as longitudinal unit conductance, transverse unit resistance, average longitudinal resistivity, average transverse resistivity and anisotropy were also calculated. Results reveal that lithology exists in the study area comprised of clay, highly weathered granitic gneiss, weathered granitic gneiss, jointed granitic gneiss, fractured granitic gneiss and highly compacted rock. Highly weathered/weathered granitic gneiss in unconfined conditions serve as shallow aquifer zones and supply water for agricultural activities. It was observed that groundwater quality deteriorates due to intensive agricultural practices. The existence of weathered granitic gneiss along the pond shore possesses high permeability and hence the interaction exists in these zones between pond and aquifer. Measured electrical conductivity was low in the northern region of the study area also implies the existence of an interaction between pond and wells in these zones. The identification of groundwater potential zones through electrical resistivity method suggest the importance of implementation of emerging agricultural management systems to avoid the groundwater quality deterioration of the study area.
