AbstractFly ash and bottom ash are being used extensively for stabilization of roads. Unpaved county roads in rural areas are often being resurfaced with bottom ash to improve their stability. A preliminary, uncontrolled examination was conducted to assess the environmental problems that may result from the use of fly ash and bottom ash on highways. To do this, soil, plant and run–off water samples were collected from county roads and highways in Oklahoma that were constructed using either of the two ash forms. These samples were analyzed for fourteen elements of which eight are under the USEPA regulation list of priority pollutants for solid waste and drinking water. The results indicated that the allowable limits for six out of the eight elements were exceeded in the run-off water samples. Compared with the control, fly ash, bottom ash, coal and soil-core samples all contained significantly higher levels of all elements; however, except for barium all were below the regulatory levels. The concentrations of As, Sb, Pb, Ni, Se, and TI in the run-off water samples are high enough to be of concern, although they are below the allowable limits for drinking water. These six elements are found at much higher levels in the fly ash and bottom ash than in the input coal. More Ba is released into the run–off water when the roads were under heavy traffic. Although there was no visual damage observed on the collected plant samples, much higher than normal levels of most metals, were obtained in the tissues.

Abstract Sporadic outbreaks of diarrhoea in children in the Vhembe rural areas could be an indication of contamination in drinking water sources. In areas where improved water sources are used, not all rural households experience the benefits of these improved water sources. Water samples were collected from boreholes in three wards in the Vhembe District to determine microbiological risks over a 5-month period. A Water Point Mapping tool was used to indicate the borehole distribution. Water samples were taken from each functional borehole and analysed for total coliform and Escherichia coli counts, electrical conductivity, pH and temperature. A multiplex PCR protocol was used for identification of pathogenic E. coli. A total of 125 boreholes were identified of which only 12 were functional. Seven boreholes tested positive for total coliforms and E. coli counts. Four boreholes (33.3%) tested positive for diarrhoeagenic E. coli. Fifty-eight percent (58%) of water samples were without health risks, 17% were low risk and 25% could cause infection according to the South African water quality standards. This study indicated the importance of the role of the Municipalities and the maintenance plans that need to ensure that all boreholes are functional and provide safe drinking water to the rural communities.

The Impact

Objective: We assessed the degree of risk to the health of the rural population of different ages with constant peroral intake of nitrates with drinking water. Materials and methods: The study was conducted within the rural residential areas of Zhytomyr region and it is a part of the research "Ecological and social assessment of the state of rural residential areas in the context of sustainable development." Drinking water samples were taken from public and private sources of decentralized water supply: wells, bore-wells and natural sources. A total 549 water samples were taken. In the study, we used general scientific methods: analytical, field, laboratory and statistical ones. Results: Among the studied areas, the largest excess of the average content of nitrates was recorded in drinking water of rural settlements of Berdychiv district. The risk assessment showed that the children aged 0-10 years were the most sensitive population to nitrates, and the women were more vulnerable to nitrates than the men among the adult population. The significant correlations between an excess of nitrate content in drinking water and cancer among adults and children in Berdychiv district have been proven. Conclusions: It has been proven that with a constant oral intake of nitrates with drinking water, harmful effects on the health of the rural population are observed, which, according to their sensitivity to their action, were distributed as follows: children 0-10 years old> adult women> adult men> adolescents.Taking into account the results obtained, it is necessary to monitor constantly the quality of drinking water sources of decentralized water supply in rural areas and to inform the rural population about water quality and the impact of its impurities on human health.

This paper addresses two aspects namely a new method for manufacturing of percolating concrete blocks using different proportions of concrete mixture such as Portland cement, Coarse aggregates, fine aggregates, limestone, and water have been designed. Apart from this an attempt has also been made by adding small quantities of additives such as fly ash, rice husk ash etc. for its strength and suitability on par with the normal Concrete blocks. Another is a partial replacement of cement with supplementary cementation materials such as fly ash and metakaolin in different proportions for reducing high grade cement consumptions been proposed. The design of a Pervious Concrete is made in such a way that it allows the entire surface run off water to percolate down without retaining any drop/quantity in it. Thus, it is named as water percolating Pervious Concrete/ porous concrete. An alternative for reducing cement usage in concrete makes concrete eco-friendly. Thus, there comes an idea of partially replacing cement with supplementary cementations materials, The concern has been growing in recent years towards reducing the pollutants in water conservation and the environment. The continual urbanization has led to the increase in impervious surface area of the cities, further leading to blockage in percolation of precipitation from rainfall. This result is excess surface run off. To counteract this, pervious concrete is the solution. Hence, the pervious concrete having 15% to 35% interconnected pores by volume, allows direct infiltration of water through its structure. Since the strength of this block for highway suitability of roads is not yet tested. The main aim of this paper is to improve the strength characteristics of porous concrete. However, on comparison, with the published data it is suitable for foot paths/ pathways and parking lots and as driveways in the residential and small rural areas where less vehicular traffic. This will help in reducing the risk of water clogging and recharges the nearby ground water level. The Maintenance of the slab is also minimum and can be repaired and cleaned easily. Thus, it is worthy and useful in many ways

The present study aims to determine the quality parameters of drinking water of rural Tharparkar i.e., Diplo area. The quality parameters examined in water samples were pH, TDS, and EC. A total of 20 samples were collected randomly from different sources of drinking water (dug well and hand pump water) from Diplo Sub District of Tharparkar. Results showed that water samples of hand pump source have elevated quality parameters (i.e., pH range was 5.7-6.0 and TDS range was 1579-2120mg/L) as compared to well water samples (i.e., pH range was 5.09-6.60 and TDS range was 497-1182mg/L). Therefore, it is concluded that as per guidelines of WHO and EPA, water from well sources is somehow good to ensure well-being of human population residing in the area. While water from the hand pump source is loaded with high TDS and EC (greater than WHO limit). The aforementioned parameter is highly linked with EC as well as pH. It is directly proportional to the conductivity and inversely proportional to the pH. Further, studies need to be conducted in this measure to evaluate quality of drinking water in rural areas of Sindh province.

Abstract This study aims at assessing the determinants of microbiological contamination of household drinking water under multiple-use water systems in rural areas of Ethiopia. For this analysis, a random sample of 454 households was surveyed between February and March 2014, and water samples from community sources and household storage containers were collected and tested for fecal contamination. The number of Escherichia coli (E. coli) colony-forming units per 100 mL water was used as an indicator of fecal contamination. The microbiological tests demonstrated that 58% of household stored water samples and 38% of protected community water sources were contaminated with E. coli. Moreover, most improved water sources often considered to provide safe water showed the presence of E. coli. The result shows that households' stored water collected from unprotected wells/springs had higher levels of E. coli than stored water from alternative sources. Distance to water sources and water collection containers are also strongly associated with stored water quality. To ensure the quality of stored water, the study suggests that there is a need to promote water safety from the point-of-source to point-of-use, with due considerations for the linkages between water and agriculture to advance the Sustainable Development Goal 6 of ensuring access to clean water for everyone.

This study was intended to evaluate the fluoride concentration in drinking water and its effect on dental fluorosis in Southwest Saudi Arabia. Water samples were gathered rom wells, filtration plants and commercial brands (bottled water) in distinct urban and rural areas of Asir region of the Kingdom of Saudi Arabia (KSA). Overall, 63 water samples were collected from 12 locations and 9 brands of bottled water. ExStik® FL700Fluoridemeter was used in the analysis of water samples for fluoride levels. The total number of screened patients for dental fluorosis, aged between 9 and 50 years, was 1150; among them, 609 were males and 541 were females. Dean’s index criteria were used to examine the patients for dental fluorosis. The results revealed that fluoride levels varied between 0.03 and 3.8 ppm. People who drank well water displayed increased fluoride levels (>0.81 ppm). The prevalence of dental fluorosis was established to be 20.43% among the total number of examined patients. The findings of this study show very mild to moderate dental fluorosis prevail among the patients who consume well water in the Asir region.

The paper analyzes the water supply in the rural part of Zagreb County, which is based mainly on individual water supply sources, i.e. dug or drilled wells and Norton pumps.The aim of the paper is to investigate whether there is a difference in health quality of drinking water taken from the wells and taken from the Norton pumps. The wells are supplied from an aquifer that lies at a depth of 12 to 14 meters, while the Norton pumps reach a depth of 6 and 7 meters.The analysis of water samples taken from the water supply sources revealed that the water does not basically comply with the Ordinance on the parameters of assessment and the methods for the analysis of water intended for human consumption, the Act on Water Intended for Human Consumption. Organoleptic indicators such as color and clarity do not satisfy, while the physical and chemical parameters such as pH and conductivity satisfy the criteria set for both water supply sources. Of all the chemical parameters only the chloride content was within the permitted limits, while the oxidativity, the content of ammonium, nitrite and nitrate were above the allowed limits in water samples taken from the wells and Norton pumps. Microbiological indicators in the analyzed samples, i.e. the number of colonies at 37 ° C and 22 ° C, as well as total coliforms also do not satisfy the requirements of the Ordinance. In order to use the water for drinking it is necessary to perform the conditioning and disinfection of wells, while with the Norton pumps these interventions are almost impossible to perform.

Groundwater is a major source of drinking water in both urban and rural areas of Solapur. Solapur city is growing rapidly in terms of population, changing lifestyle and intense competition among users-agriculture, industry and domestic sectors is driving the groundwater to fall. Besides, the discharge of untreated wastewater through bores and leachate from unscientific disposal of solid wastes also contaminate groundwater, thereby reducing the quality of freshwater resources. In the work of Solapur, water samples were collected from around the villages in thermal power plant and water quality assessment was carried out from April 2015 & November 2015. The surface and groundwater characteristics have been established through analysis of water samples collected during the study area with respect to Physico-chemical characteristics and pollutant levels and the same has been compared with quality criteria for drinking water (IS: 10500). From the study, it is observed that the samples collected at all the 11 locations during pre-monsoon season are well within the prescribed limits laid by IS10500. We obtained fewer values in Post Monsoon are compared to Pre Monsoon season because of scanty rainfall.

Municipal waste combustion typically involves both energy recovery as well as volume reduction of municipal solid waste prior to landfilling. However, due to environmental concerns, municipal waste combustion (MWC) has not been a widely accepted practice. A primary concern is the leaching behavior of MWC ash when it is stored in a landfill. The ash consists of a finely divided fly ash fraction (10% by volume) and a coarser bottom ash (90% by volume). Typically, MWC fly ash fails tests used to evaluate leaching behavior due to high amounts of soluble lead and cadmium species. The focus of this study was to identify specific lead bearing phases in MWC fly ash. Detailed information regarding lead speciation is necessary to completely understand the leaching behavior of MWC ash.
