Ecological condition of Perandoor, Edappally canals worsens
The Hindu
Total coliform count exceeds maximum permissible limits by 320 and 230 times
Three months after detecting alarming levels of faecal contamination, the ecological condition of Perandoor and Edappally canals continues to be on the decline. Tests results of samples taken from five new monitoring stations on March 15 by the State Pollution Control Board revealed that the total coliform count, indicating faecal contamination, has exceeded the maximum permissible limits by 320 times in Perandoor canal. In Edappally canal, the maximum permissible limit was breached by nearly 230 times. The Hindu had reported on January 28 that the total coliform count had exceeded the maximum permissible limits by 160 and 96 times respectively in Perandoor and Edappally canals. The tested samples were collected between December 9 and December 23 last year. The spike in coliform count shows the indiscriminate discharge of septage into the two major canals.More Related News
