Hydrogeochemical characterization of contaminated groundwater in Patancheru industrial area,southern India 总被引:1,自引:0,他引:1
The groundwater is one of the most contaminated natural resources in Patancheru industrial area due to unplanned and haphazard
industrial growth and urbanization without following basic pollution control norms. The rapid industrialization initiated
in early 1970 has started showing up its after effects few years later in the form of physiochemical contamination of the
both surface and groundwater bodies of the area. It has resulted in local people being deprived of safe drinking water, plant
and aquatic life has severely affected, and situation is deteriorating over the years in the area in spite of some preventive
and remedial measures being initiated. The focus of the present study is to understand the chemical characteristics of groundwater
and geochemical processes the contaminant water is undergoing which are normally imprinted in its ionic assemblages. The water
samples collected in pre- and post-monsoon seasons from forty two groundwater and four surface water sources were analyzed
for major constituents such as Ca2+, Mg2+, Na+, K+, CO3−, HCO3−, Cl−, SO42−, NO3−, and F−, and selected samples were tested for ten important trace metals like Fe, Pb, Bi, Mn, Cr, Co, Ni, Cu, Zn, and Cd. Na+ among cations and Cl− among anions dominate the water in both the seasons where as Ca2+, HCO3−, and Cl− show significant reduction in their ionic strength in post-monsoon. The groundwater in general is of mixed type, but most
of it belong to Na+–Cl−, Na+–HCO3−, Ca2+–Mg2+–HCO3−, and Ca2+–Mg2+–Cl− facies. The Na+ and Ca2+ are in the transitional state with Na+ replacing Ca2+ and HCO3−–Cl− due to physiochemical changes in the aquifer system. The evaluation of hydrochemistry through various ionic indices, ratios,
and plots suggest that silicate–carbonate weathering, ion exchange, dissolution, and evaporation processes are responsible
for origin of the present chemical status of the groundwater which is also controlled by the contamination from extraneous
sources that could have accelerated the dissolution processes. Gibbs plots authenticate that the evolution of water chemistry
is influenced by interaction of percolating water with aquifer matrix apart from anthropogenic enrichment of elements which
get over concentrated due to evaporation. 相似文献

The aim of this paper is to inform urban design practice through deeper understanding and analysis of the social dynamics of public outdoor space in ethnically diverse neighbourhoods. We hypothesise that findings from ethnographic research can provide a resource that improves cultural literacy and supports social justice in professional practice. The primary method is a meta-synthesis literature review of 24 ethnographic research papers, all of which explore some dimensions of public open space use and values in UK urban contexts characterised by ethnic and racial diversity. We summarise thematic understandings and significance of neighbourhood places of shared activity, parks, spaces of passing-by and of retreat. We evaluate the implications for intercultural social dynamics, exploring the spatial and temporal dimensions of conviviality and racism in public open space. We then argue that it is possible to develop principles for urban design practice informed by this work, and propose four for discussion: maximising straightforward participation, legitimising diversity of activity, designing in micro-retreats of nearby quietness and addressing structural inequalities of open space provision. We conclude that ethnographic research can provide detailed insights into the use of the public realm and also inform a more nuanced understanding of outdoor sociality relevant for an increasingly diverse society. The challenge is two-fold: for ethnographers to become less cautious in engaging with decisions and priorities regarding how cities change, and for urban designers to explicitly embed informed understandings of difference into their broad desire for inclusive public space. 相似文献
