Significance of Precipitation Chemistry for Delineating Polluted Parts of Maheshwaram Aquifer System,Andhra Pradesh

The chemistry of subsurface water bodies is difficult to understand unless precipitation chemistry and atmospheric processes are taken into consideration. Limited pioneer work has been carried out on considering precipitation chemistry.Polluted zone delineation is very much significant before the planning for any of the remedial measures.The dual contamination is a common problem noticed

片岩含水层中涉及几种电子给体的快速脱硝化作用

涉及几种电子给体(有机物、黄铁矿、二阶铁)的脱硝化作用,可以部分地说明 Brittany 地区片岩含水层中硝酸盐浓度的降低。至少,细菌的出现可以增强前两种物质的作用。一个小型示踪试验已经验证了快速自养型脱硝化作用的存在,从而解释了含水层中某些部位硝酸盐的缺乏。除了黄铁矿的氧化作用外,水中硫酸盐的浓度与诸如黄钾铁矾和钠明矾石等次生矿物相的沉淀关系不大,这意味着脱硝化作用主要发生在这种作用更为有效的小裂隙网络中,而不是在大裂隙或断裂中。
