|Environmental Quality Report 2013 (DOE, Malaysia)|
The present compliance of the discharge concentration also does not consider the cumulative (or additive) impacts of the industrial and domestic wastewater being discharged into a single watershed. This situation and the absence of a water quality model for that particular river will disallow for us to target a river classification for that river i.e. Class I, II, III, IV or V.

Complaints from villagers in the Sg Sepetang watershed, specifically from Kg Dew, Kamunting brought me to the place and made me do a investigation of the water pollution issues.
Sg Sepetang is a tidal influenced river with a relatively small amount of fresh water influx. Mangroves trees and nipah palms lined the banks from Kuala Sepetang until Kg Dew. River fishing especially for the Udang Galah (Macrobrachium rosenbergii) is an important resources for the locals and about 6 or so years ago, ecotourism in the form of firefly tours became an important source of income to some locals. Local boatmen usually take tourists Sg Sepetang between 7 to 10 pm at night to view the one of the wonders of Nature - congregating fireflies synchronizing the flashing of their mating lights.

The effluent discharge are supposed to "comply" with Standard B i.e. BOD at or below 50 mg/L and COD at or below 100 mg/L but my laboratory analyses indicated non-compliance with BOD at 64 mg/L and COD exceeding 200 mg/L. But the discharge of the effluent into the drain (which flows through Kg Pak Dollah before discharging into Sg Malai about 3.5 km away) is at 3 L/s and the drain became anoxic about 1.6 km away.

So, we called in Aduan Rakyat TV3 to do a coverage on the issue of the pollution of Sg Sepetang on 8 and 9 April.
