and non-geogenic (dumping of domestic wastes, leakage of drainage waters and septic tanks, heavy usage of agrochemicals, etc).
Sulphate and NO3 − are the sources of soils, evaporites, fertilisers, domestic wastes, leakage of septic tanks, etc. (Todd 1980; Drever 1997; Subba Rao 2014).
Impacts of saline water (used for salt pans and aqua-cultural activities), domestic wastes, leakage of septic tanks and clays are responsible for additional source of Na+ (Todd 1980; Hem 1991; Subba Rao 2014; Subba Rao et al. 2014a, b).
On the other hand, a predominance of Cl distinguishes it as a discharge zone and arises mainly by geogenic (clays), anthropogenic (domestic wastes, leakage of septic tanks and agro-chemicals) and marine (salt pans and aqua-cultural activities) sources.
Agricultural and urban wastewater, improper disposal of municipal and industrial wastes, leakage in septic systems, landfill leachate, animal manure are sources of nitrate anion contamination (Bhatnagar et al. 2010).
Nitrate (NO3) sources in groundwater is due to decaying organic matter, sewage wastes, leakage of septic tanks, and fertilizers (Subrahmanyam and Yadaiah 2000), leaching of nitrate with the percolating water.
The influences of salt pans and aqua-cultural activity on the groundwater system are dominant in the central part, while the impact of domestic wastes, leakage of septic tanks and agro-chemicals on the groundwater body is predominant in the remaining part.
A waste water leakage forced the closure of the plant more than two weeks ago.
A waste water leakage began a week ago, and analysts said this disruption could push the miner into a major share issue.
