Heavy metal concentration in the river water samples like Mercury, Lead, Cobalt, Nicale etc may be measured
the future studies at different locations where there is a wastewater outfall from industries.
3. Any inconsistency in the results may be attributed to the approach adopted in sample preservation, method of
testing and expertise of the technicians. Standard approaches for such procedure should be ensured.
4. Samples should be tested as early as possible after bringing to the laboratory, preferably by 24 hours. If it is
not possible, samples should be refrigerated appropriately.
5. Unavailability of adequate data required for trend analysis limits the use of such data. So, it is recommended
that continuous water quality data be monitored and collected at important locations of the river system
