A report of the test conducted by theGoa State Pollution Control Board (GSPCB) clearly indicated that fecal coliformhad exceeded the permissible limit.

It was also observed that rawsewage/untreated sewage was being pumped into the treated water tank.
When contacted, a source at the GoaState Pollution Control Board (GSPCB) confirmed that the test result showedthat the fecal coliform level was 920x104 (92,00,000) MPN per 100ml,instead of the permissible limit of less than or equal to 100 MPN/100ml.
“Levels of 106 or 108are usually found in untreated sewage. This particular reading of 104indicates that the sewage was not effectively or efficiently treated,” said thesource.
