| الملخص: | Dam is physical barrier that was constructed purposely to impound water or underground
streams, which serve the primary purpose of retaining water. It can be also use as floodgates
or levees to manage or prevent water flow into specific land regions. This study is focusing
on documentation of the environmental management, legislations and guidelines, and water
quality analysis. Documentation such as EIA study report is mandatory as accordance to
Malaysia legislation. Therefore, strict enforcement should be carried out to regulate existing
legislation and also to monitor impacts from the dam's development. Water quality
sampling was carried out at Murum River and its tributaries at six sampling locations.
Results of the water quality analysis showed parameters such as BOD5, COD, TSS,
turbidity, ammoniacal nitrogen and total coliform count exceeded the National Water
Quality Standards for Malaysia (NWQS) compliance limit indicating the large number of
workers population at the dam site as the main contributing factor. Pollutants are mostly
from sewage discharge, soil erosion and decomposing organic materials. |
