The World Health Organization (WHO)/United Nations Children??s Fund (UNICEF) Joint Monitoring Programme (JMP) for Water Supply and Sanitation was designed to provide reference figures for access in individual countries to safe water. The JMP is based on non-administrative or nongovernment data from national-level surveys such as the Multiple Indicator Clusters Survey (MICS) or Demographic Health Survey. In the 2007 JMP report, India is noted to have water supply coverage of 89% (95% in urban areas and 85% in rural areas) compared to the Government of India estimates of 95%. The central state of Madhya Pradesh is noted by the Government of India to have coverage of 60%. However, the definition of access to safe water currently does not consider the quality or safety of the water being consumed. This paper, therefore, presents results from the application of a statistical tool (random multiple cluster technique??termed Rapid Assessment of Drinking Water Quality [RADWQ]) to Indore Zone in Madhya Pradesh. When results provided by the RADWQ technique are compared to the JMP MICS data, coverage levels reported in the JMP are reduced by up to 40% due to the high risk of microbiological (thermotolerant coliforms) contamination. In Indore Zone, the coverage of safe water reduced from 42% to 25% through the inclusion of the water safety parameters. The study recommends the inclusion of water quality/safety data in reported data under the UNICEF/WHO JMP. 相似文献

In India, the per capita water availability is reducing day by day due to rapid growth in population and increasing water demand. Greywater treatment and reuse is one of the feasible options in developing countries like India to overcome this problem. A greywater collection, treatment and reuse system was designed and implemented in an urban household having a water requirement of 165 liter per capita per day (lpcd) and a greywater generation rate of 80 lpcd. An upflow-downflow greywater treatment plant having a screening, sedimentation, filtration and disinfection as major treatment processes was constructed and treated greywater is used for toilet flushing and to irrigate the vegetables in the backyard of the household. Greywater characterisation indicates that COD and BOD are sufficiently reduced during the treatment and there is also substantially reduction in Escherichia coli count. The payback period of this greywater treatment and reuse system is estimated to be 1.6 year. 相似文献

The Pithampur Industrial sectors I, II, and III, located approximately, 45 km from Indore in Central India have emerged as
one of the largest industrial clusters in the region. Various types of industries ranging from automobiles to chemicals and
pharmaceuticals have been set up in the region since 1990. Most of the industries have effluent treatment plants (ETP) for
treating wastewater before its disposal on land and/or in water body. The present study is an attempt to assess the groundwater
quality in the watersheds surrounding these industrial sectors to develop the baseline groundwater quality in order to enable
the policy makers to facilitate decisions on the development of industries in this region. The industries are located in two
sub-watersheds, namely, Gambhir river sub-watershed and Chambal river sub-watershed. Geologically, the study area is located
in the Deccan traps of Cretaceous to Paleocene age. The different basaltic flow units underlie clayey soils varying in thickness
from 2–3 m. The aquifer is mostly of unconfined nature. Samples have been collected from a network of observation wells set
up in the watersheds. The water quality analysis of the groundwater samples has been carried out six times during three hydrological
cycles of 2004, 2005, and 2006. The results indicate that a few observation wells in the vicinity of the industrial clusters
have very high TDS concentration and exceed the Bureau of Indian Standards (BIS) guideline for TDS concentration. The contamination
of groundwater has been more severe in the Gambhir watershed as compared to the Chambal watershed. The presence of the impermeable
clay layers has resulted in a slow migration of contaminants from the sources. The findings reveal that there is no significant
groundwater contamination in the Pithampur industrial sectors except in the vicinity of the industrial clusters, which indicates
that there is good environmental space available for the expansion of industrial units in the Pithampur industrial hub. 相似文献

This paper provides a comprehensive characterization of mineral waste such as fly ash, bottom ash, slag and construction demolition (C&D) collected from four different thermal power plants, three steel plants and three C&D waste generation sites in India. To determine utilisation potential and environmental concerns, as received fly ash, bottom ash, slag and C&D waste were analysed for physico-chemical, mineralogical and morphological properties. The physico-chemical properties analysed include pH, moisture content, acid insoluble residue, loss on ignition(LOI), carbon content, fineness, chloride content, sulphate content, reactive silica content, XRF and heavy metal analysis. Morphological and mineralogical characteristics were investigated using scanning electron microscopy–energy dispersive X-ray. Particle size distribution was obtained using particle size analyser. The material analysed has different compositions and were selected with a view to determine their suitability for different applications in cement and concrete industry and for further research studies. 相似文献

A water safety plan for the city of Nagpur was developed by the National Environmental Engineering Research Institute (NEERI) and Nagpur Municipal Corporation (NMC). Possible hazards were identified through field visits. Based on this, an improvement plan was drawn up to suggest corrective actions and a time frame for implementation. The findings of this study are being used to modify or repair components of the water supply system and upgrade management procedures. This paper highlights the lessons learnt during implementation of the WSP and the key challenges faced. 相似文献

On-site sanitation has emerged as a preferred mode of sanitation in cities experiencing rapid urbanization due to the high
cost involved in off-site sanitation which requires conventional sewerages. However, this practice has put severe stress on
groundwater especially its quality. Under the above backdrop, a study has been undertaken to investigate the impact of on-site
sanitation on quality of groundwater sources in two mega cities namely Indore and Kolkata which are situated in two different
geological settings. The parameters for the studies are distance of groundwater source from place of sanitation, effect of
summer and monsoon seasons, local hydro-geological conditions, and physico-chemical parameters. NO3 and fecal coliform concentrations are considered as main indexes of pollution in water. Out of many conclusions which can
be made from this studies, one major conclusion is about the influence of on-site sanitation on groundwater quality is minimal
in Kolkata, whereas it is significant in Indore. This difference is due to the difference in hydrogeological parameters of
these two cities, Kolkata being on alluvium quaternary and Indore being on Deccan trap of Cretaceous to Paleogene age. 相似文献

This study has investigated the common risks associated with the water quality changes from the source to the consumer households and the associated disease burden in the piped water supplies. Samples from the source to the household storage from Nagpur City were collected and analysed for heavy metals, nutrient and microbial parameters. Sanitary risks were identified at the households during the socio-economic and sanitary survey. The water quality deterioration was the most at household storage around 30.3 % indicating that measures need to be taken to safeguard the water quality at the consumer level. Then, 31.2 % of the samples collected from public standposts and handpumps were positive for faecal contamination which implies that it is the weaker sections of the society who suffer the consequences of drinking unsafe water the most. On the basis of the laboratory results, risk analysis by surveying the WTPs, point-of-use behaviour at households and sanitary status at different socio-economic strata, the Water Safety Plan for Nagpur City was structured. The aim was to ensure that safe and improved water is reached to the individual household. 相似文献
