The Impact

Crude oil exploration and its associated spillage pose a major threat to the environment in Nigeria and if not checked and managed properly, could lead to total annihilation of the ecosystem especially in the Niger Delta Region. Therefore, this study examines the impact of oil spill on soil, water and shrimps from Maa-or gbor. Water and soil samples were collected in the upstream, midstream and downstream, while shrimps from the river were also collected. They were digested with nitric acid. The heavy metal components were analyzed using atomic absorption spectrophotometer while physiochemical parameters were determined using different analytical methods. The result of the metals concentration in the soil showed that the values of some of the metals analyzed were within the acceptable limit of FAO/WHO except for Cu, Mn and Fe values. The result of water quality showed that pH values of the stations were in the range of 6.08-6.20 and a mean value of 6.15± 0.05 for the three stations, which is lower than the limit (6.5- 8.5) recommended for drinking water. Also the result showed that Station C had the highest conductivity value when compared with other stations, and significantly differs when compared with station B. However, the values of the electrical conductivity in all the stations were lower than that of FEPA acceptable limit of 250, while the mean value for the stations was 60.9± 3.42. Trace metals concentration in shrimps was below FAO/WHO acceptable limit. The result obtained for water quality index was147. This value is above the recommended standard for drinking water, thus indicates poor quality water status of Maa-or gbor and unfit for human consumption.

The Impact

The present work was conducted to document the problems raised regarding low-flow in the Rosetta branch, Egypt and to develop management options to protect drinking water sources. The water quality was monitored during low-flow periods at four drinking water intakes. Results showed an increase in electric conductivity (EC), ammonium (NH4), nitrite (NO2), phosphate (PO4), and total organic carbon (TOC) during the low-flow period. EC ranges from 454 to 1,062 μS/cm and the mean value is 744. Ammonium ranges from 0.38 to 18.5 mg/L and the mean value is 5.45. NO2, PO4, and TOC have mean values of 0.73, 1.85, and 6.71 mg/L, respectively. Statistical evaluation revealed the association of NH4, EC, and PO4 that are good indicators for the load of wastewater. High ammonium often refers to a bad situation regarding oxygen while high nitrite indicates the first oxidation for wastewater through microbiological processes. The low-flow action has a serious impact on drinking water source. A high content of ammonium has delayed coagulation, enhanced algae growth, and prevented the breakpoint being reached during chlorination processes. Potential management options to deal with water scarcity and low-flow, meanwhile reducing the contaminant load in the source drinking water were proposed.

The Impact

One of the spiteful impacts of landfill sites is the emission of leachates into ground water. The study examined the impact of landfill site on ground water in MgbojiNdokiOyigbo Local Government Area, Rivers State. The study sought to assess the quality of underground water in relation to WHO best standard. The study adopted a laboratory examination, assessing water quality parameters such as hardness, TDS, EC, DO, BOD, chlorine, zinc, pH, temperature, salinity, COD and copper. The study sampled 15 boreholes that are up to or less than 500m from the landfill site and another borehole at 1000m from the landfill site, which serves as a control point for the study. The paired sample t-test was adopted in analyzing the formulated hypotheses. The result of the study revealed that bore holes that are 500m or less are more contaminated than boreholes that are 1000m away from the landfill sites. Furthermore, water quality from boreholes that are 500m or less are unfit for human consumption because they do not meet the acceptable limit postulated by WHO, while boreholes that are 1000m away from the landfill are suitable for human consumption because they meet the acceptable limit by WHO. The study recommends that government should regulate human settlement and development within areas that are too close to landfill sites.

In order to use a healthy fluid for human consumption, water should be aesthetically acceptable, should be free from apparent turbidity, colour, odour, objectionable taste and microbial contamination. The demand for such potable water has been an important issue, due to poor quality of ground water and rapid increase in population every year. A case study related of drinking water is presented together with our laboratory management, the staff involvement, the implementations of the quality objectives and all our activities related to water control. Fairness and reliability of testing and standardized methods performed by a laboratory are determined by many factors including: human factors; accommodation and environmental conditions; methods of testing and standardized methods; equipments and methods validation; measurement traceability, sampling and handling of testing measurements. This is an implementation procedure of drinking water analyses from a laboratory, development of strategies to accreditation system and obtaining the certified measurements. Accreditations protocol recognizes the laboratories competence to test standardize and use thi s international standard as a basis for their authentication. Implementation of risk management strategies include national standards developed from the international guidelines. These are describing the minimum requirements of safe practice to the consumer’s health and concentrations values for indicators of water quality. In the development and implementation of standards it is essential to take into account legislation regarding water and public health, government official laws and if is assessed the capacity of these regulations.Surveillance of drinking water quality can be defined as “the continuous and vigilant public health assessment and review of the safety and acceptability of drinking water supplies”.

Poor drinking water quality can affect pigs’ health and performance. The disinfection of water may enhance microbial water quality. In this study, bacteria and endotoxins in sodium hypochlorite-treated and -untreated water from one pig nursery were analyzed. Water samples were taken from incoming water and from compartments with treated and untreated water at the beginning and end of pipes and from nipples. The farm was visited 14 times to measure total bacteria counts and concentrations of Pseudomonas spp. and endotoxins. Additionally, the occurrence of coliform bacteria was analyzed. A mixed model analysis revealed significant reductions in total bacteria counts and Pseudomonas spp. in treated water at the beginning of pipes and at nipple drinkers. The differences between bacteria concentrations at the end of pipes had no clear trend. Endotoxin concentrations were approximately equal at the beginning of pipes and at nipple drinkers but were found to have differences at the end of pipes. The occurrence of coliform bacteria was significantly reduced in treated water. The application of sodium hypochlorite can significantly reduce bacteria in water pipes. Endotoxin concentrations were mostly unaffected by water treatment. Disinfection of the dead-end pipe sections failed, and thus these parts should be regarded as potential contamination sources.

The Impact

We examine the impact of poor water quality on avoidance behavior by estimating the change in bottled water purchases in response to drinking water violations. Using data from a national grocery chain matched with water quality violations, we find an increase in bottled water sales of 22 percent from violations due to microorganisms and 17 percent from violations due to elements and chemicals. Back-of-the envelope calculations yield costs of avoidance behavior at roughly $60 million for all nationwide violations in 2005, which likely reflects a significant understatement of the total willingness to pay to eliminate violations.

The Impact

Purpose Although access to safe drinking water is one of the most important health-related infrastructure programs in the world, drinking water remains a large problem in China today, especially in rural areas. Despite increased government investment in water resource protection and management, there is still an absence of academic studies that are able to document what path the investment has taken and whether it has had any tangible impact. The purpose of this paper is to analyze the impact of drinking water investment on drinking water in China. Design/methodology/approach The authors make use of nationally representative data from 2005 and 2012 to measure the impact of drinking water investment among 2,028 rural households in 101 villages across five provinces. Both ordinary least squares regression and probit regression are used to analyze the correlates and the impact of drinking water investment. Findings The authors demonstrate that water quality was likely a significant problem in 2004 but that China’s investment into drinking water appears to have resulted in initial improvements during the study period. The authors show that the most significant change came about in terms of hardware: villages that received more drinking water investment now have more piped tap water and more access to water treatment infrastructure (disinfecting and filtering facilities). High rates of rural resident satisfaction with drinking water suggest the effects of drinking water investment are being felt at the village level. Originality/value To the authors’ knowledge, this is the first empirical study on drinking water investment over time in rural China using nationally representative data.

AbstractMany people prefer to drink bottled water instead off the tap water. The bottled water is stored in the plastic bottles sometimes for long time. These plastic bottles might leach out some harmful materials into the water especially when exposed to temperature alteration, which may affect human health. This research work focused on investigating the effect of changing temperature on the bottled water quality. The work studied the effect of heating water in plastic bottles by sun, oven, and microwave. The study included also the impact of cooling and freezing the bottled waters. Results showed that temperature alterations caused changes in some physicochemical properties of bottled waters such as decreasing the values of pH and TDS and increasing levels of fluoride and chloride. In addition, the concentration levels of some physiochemical parameters exceeded the permissible values for drinking water. With temperature alterations, all levels of heavy metals in bottled waters were minimal except some small concentrations of copper and zinc. Results confirmed also differences in behavior between the bottled water brands exposed to the same temperature alterations. Heating bottled waters above 50 °C is alarming problem on the water quality. This is because above this degree, many alternations were observed in the water content. The outcomes of this work are useful for improving the current legislation on bottled waters and their storage.

The Impact

The indiscriminate disposal of industrial effluents and solid wastes in surface water bodies is detrimental to humans and aquatic organisms. Water quality monitoring is critical to identify pollutants of concern and develop effective management strategies. Hence, this study was conducted to assess the impact of waste disposal on the water quality of Aba Waterside River, Ogbor hill, Aba. Grab samples were collected upstream, midstream and downstream and some physicochemical and microbiological parameters were analyzed in accordance with standard methods for the analysis of water and wastewater. The results were compared with the Nigerian standard for drinking water quality and the national environmental effluent limitation regulations. Turbidity levels (10 -31mg/l) exceeded the maximum permissible levels for drinking water (5mg/l) and may be associated with higher levels of embedded disease-causing microbes and potentially harmful organic and inorganic substances. The biological oxygen demand midstream (1960mg/l) was remarkably high due to the effluent discharged from the abattoirs at that point. Fecal coliforms (3-198MPN/100ml) were detected in all samples, indicating the presence of other potentially harmful microorganisms. The findings of this study indicate that the water is unsuitable for direct drinking water purposes and stringent water quality control measures should be implemented.

The Impact

This peer-reviewed paper examines the risks and responsibilities of water providers and the process resource companies should undertake to document how they will deliver a safe and secure water supply to their employees and contractors, and the communities in which they operate, thereby reducing the risks of water quality incidents and managing the impact to the organisation should an incident occur. Water quality incidents can have major impacts to human health and the brand perception of the resource company supplying the water, and can potentially shutdown resource abstraction. Resource companies have a duty of care to provide a secure and safe drinking water supply. This is reinforced by state health departments directing resource organisations to comply with the Australian Drinking Water Guidelines (ADWG), which were updated in 2011 (National Health and Medical Research Council, 2011). Organisations in the CSG industry experience an additional challenge—managing water by-product from gas extraction. There are drivers for the beneficial use of this water—including irrigation, aquifer recharge and municipal supply—resulting in changes to legislation in Queensland (DERM, 2010) that require a process similar to ADWG recommendations, where beneficial use or disposal may impact potable supplies. The ADWG provides clear guidance to potable water providers—whether they are supplying a few consumers or major towns requiring a Drinking Water Quality Management System (DWQM System). This guidance includes documenting a clear process to securing a clean water source, making the water safe to consume and proving it is safe. Developing a DWQM System enables resource companies to understand issues in supplying drinking water through regular review and improvement, while minimising and managing the health risks to consumers.
