Ambient air testing at KRC coach care centre found within limits
HERALD REPORTER
MARGAO, JUNE 30
The Konkan Railway Corporation has claimed that testing of water discharged at its coach care centre at Davorlim has shown that the results were within the prescribed limits.
KRC Sr Manager, Public Relations & Protocol, Baban Ghatge further said that testing of ambient air collected at the coach care centre also showed the tests were within the prescribed limits.
KRC carried out the different tests through Italab, a government recognized laboratory.
Incidentally, the test result assumes significance given that the Goa Pollution Control Board had recently maintained that the water samples tested from the coach care centre were found beyond the permissible limits.
Water samples tested by Italab on behalf of the KRC revealed that the pH was found 6.74 when the acceptable limit was 5.5-9.0.
As far as the total suspended solids are concerned, the actual results turned out 49 mg/ltr when the acceptable limit was 100 mg/ltr.
The Bio-Chemical Oxygen Demand was found 17.50 mg/ltr when the acceptable limit is 30 mg/ltr, while the Chemical Oxygen demand was found to be 105.60 mg/ltr as against the permissible limit of 250 mg/ltr.
Incidentally, while the Goa Pollution Control Board had showed high quantity of oil and grease in the water, the latest testing revealed that oil and grease content in the water was 1.67 mg/ltr as against the acceptable limit of 10 mg/ltr.
Sources in the Konkan Railway Corporation, however, disclosed that local official have impressed upon senior KRC officials to set up a plant for treatment of wash water from the passenger wagon washing yard for reuse.
Sources said the suspended solids need to be further reduced before their discharge or reuse.
