Odour Removal

A deep groundwater well was established in a village near Tel-Aviv, in order to supply drinking water for its 30,000 inhabitants. Although all water characteristics were within the range permitted by the Israeli regulations, operators received complaints about a funny taste and a rotten-egg odour in the water. This was attributed to the presence of 0.38 mgL–1 hydrogen sulfide. Removing the odour by the usual method of aeration was impossible because of the populated surroundings. Therefore it was decided to examine chemical oxidants for taste and odour removal. A treatment with 8 mgL–1 of chlorine successfully oxidized hydrogen sulfide but the complaints continued. This was attributed to the formation of elemental sulfur, whichis converted into polysulfide that may hydrolyze to regenerate the odourous hydrogen sulfide. Treatment with 2 mgL–1 of chlorine dioxide successfully eliminates odour completely, but produces chlorite and chlorate which are above the permitted levels. A partial solution to this problem was found by a consequential treatment with 2 mgL–1 of ClO2 for 10 min. followed by 1.5 mgL–1 of chlorine (30 min.). In this case the chlorite is reduced substantially to be within the permitted level. In addition, such treatment regenerates some of the chlorine dioxide thereby increasing its residual. The odourous H2S can also be eliminated with 3 mgL–1 of ozone. Advantages and disadvantages of the above treatments are discussed.

Urban Village

The aquifer of the peri-urban/rural areas of Chennai Metropolitan Area in Tamil Nadu acts as a source of informal water market, and a huge amount of water is transferred and marketed by entrepreneurs, such as private water suppliers and packaged water industries. Water transfer from agricultural to non agricultural uses is not only common in India but most of the water starved developing countries experience it. It leads to temporal and spatial changes in the groundwater quantity and quality, and generates the inequity and affordability issues in accessing the water especially to the peri-urban poor. The paper analyzed the above issue with a case study conducted at Perumbakkam, a Chennai peri-urban village. The multivariate statistical analysis of field findings has been conducted in the peri-urban village for understanding the socio-economic implications of the groundwater market. The study identifies the major findings due to the prevailing informal groundwater market and emphasizes the institutional mechanism through regulatory and legal measures to protect the resource base and conservation and restoration mechanism to replenish the depleting resources.

Although it is self-evident that today’s groundwater issues have a history that frames both problems and responses, these histories have received scant attention in the socio-hydrogeological literature to date. This paper aims to enrich the field of socio-hydrogeology with a novel, historical perspective on groundwater management whilst simultaneously demonstrating the value to water history of engaging with groundwater. This is achieved by applying hydrogeological, socio-hydrogeological, and historical methods in an interdisciplinary and collaborative research process while analysing a case study of urban groundwater management over a 150-year period. In the German capital Berlin, local aquifers have always been central to its water supply and, being close to the surface, have made for intricate interactions between urban development and groundwater levels. The paper describes oscillations in groundwater levels across Berlin’s turbulent history and the meanings attached to them. It demonstrates the value to socio-hydrogeology of viewing the history of groundwater through a socio-material lens and to urban history of paying greater attention to subsurface water resources. The invisibility and inscrutability associated with groundwater should not discourage attention, but rather incite curiosity into this underexplored realm of the subterranean city, inspiring scholars and practitioners well beyond the confines of hydrogeology.
