3.6 BASELINE ENVIRONMENTAL MONITORING

The baseline environmental monitoring consists of Air, Noise and Ground water
monitoring. These environmental baseline data can represent the existing fate to
environment and can be compared with post-biomining monitoring data to evaluate
the positive effects of project on environment.

a. For baseline ambient air, noise & ground water quality monitoring 2 no. of samples
each were collected.

b. For ambient air monitoring and noise monitoring one sample was taken at site and
another sample was taken at the downwind direction of the wind rose within a radial
distance of 2.0 km from the dumping ground for one week.

c. Noise levels were measured for 24 hours continuous monitoring in dB(A) Leq.

d. The parameters covered under the baseline ambient air & ground water quality
monitoring is as represented in Table 3-11 and 3-14 respectively.
