The nutrient elements were present in high
concentration in sewage waste water, with phosphorus
(6.4 mg/L) content being 80.15% higher the content in
well waters (1.27 mg/L) and nitrate content(25 mg/L)
94.4% more than that of tube well water(1.4 mg/L). Both
were exceeding the prescribed limits of 5mg/L and
10mg/L for phosphorus and nitrate content
respectively. High nitrate concentration may be due to
the presence of urea[CO (NH2
)2
] which is the major
source of nitrogen in sewage (Ganguly and Maiti, 2004).
The sulphate content in sewage water was 125.68mg/L
which is 48.13% higher than of tube well water samples
(65.18 mg/L)
