Drinking water microbiological quality was primarily determined by enumeration of “indicator organisms”, whose presence indicates faecal contamination. The presence of the indicators is often a key in assessing potential public health risks due to bacterial pathogens and is used in drinking water quality regulations and guidelines in many countries. The enumeration of fecal coliform specificall...
Water quality of four open wells representing four localities around the Kerala Minerals and Metals Ltd industrial area, Chavara, Quilon district was studied fora period of six months from December, 2006 to May 2007 to assess the suitability of the well waters for domestic purposes. The well waters exhibited high BOD (average values from 12.87-15.96 mg l(-1)), COD (666.67-796.67 mg l(-1)), TDS ...
The effects of applied digested pig slurry on a vegetable crops field were studied. The study included a 3-year investigation on nutrient characteristics, heavy metals contamination and hygienic risks of a vegetable crops field in Wuhan, China. The results showed that, after anaerobic digestion, abundant N, P and K remained in the digested pig slurry while fecal coliforms, ascaris eggs, schisto...
background: the aim of this study was to assess the effects of road deicing salt on the quality of the ground water resources in hamadan province during winter season. methods: water samples were taken monthly from thirty wells located around the hamadan-asadabad highway. the quality of well water was examined by measuring amount of sodium, chloride, total hardness, total dissolved solid, elect...
The study is aimed to evaluate the microbiological quality of water samples obtained from beaches Munzur and Pülümür streams in Tunceli province, during summer season 2019. were analyzed for fecal indicator bacteria reveal bathing these beaches. collected 10 sampling points region between June September Fecal streptococci, total coliform, coliform determined highest August lowest May July accor...
Australian ports serve diverse and extensive activities, such as shipping, tourism and fisheries, which may all impact the quality of port water. In this work water quality monitoring at different ports using a range of water quality evaluation indices was applied to assess the port water quality. Seawater samples at 30 stations in the year 2016-2017 from six ports in NSW, Australia, namely Por...
The Commission of the European Communities (CEC) is just working out a new directive in order to regulate the agricultural reuse of sewage sludge. This new regulation will also effect a “special case” – sludge usage in a mountainous environment – which will be discussed in this paper. Three reuse sites at small wastewater treatment plants of mountain refuges at altitudes more than 2,000 m a.s.l...
The acceptability of the quality of hotwater supplied by harvested rainwater in the urban environment has been the subject of much debate in many developed countries as a result of attempts to maximise usage of harvested rainwater in order to improve city water-cycle management. Debate has centred around the issues of the microbiological quality of the heated rainwater, since many tank water sa...
In the poor zones of sub-Saharan Africa, the conventional drinking water network is very weak. The populations use alternative groundwater sources which are wells and springs. However, because of urbanization, the groundwater sources are degrading gradually making pure, safe, healthy and odourless drinking water a matter of deep concern. There are many pollutants in groundwater due to seepage o...
With climate change and a burgeoning future world population there will be an increased need to reuse treated wastewater for a variety of uses including domestic water supplies as a water conservation measure. While there are technologies for partial treatment for the reuse of wastewater, in some areas of the world there is presently unregulated reuse of wastewater for agricultural irrigation a...
