„ To classify the environmental resources - Planning for development and utilization of a water resource necessary to classify rivers according to its quality and prospective uses.

„ Collection of base-base-lineline data - To collect necessary data regarding the natural quality of water in order to indicate changes over long duration which may interfere with the present and planned uses of the water resources

15 DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT

ƒ Environmental Quality Surveillance - To assess the effectiveness of wastewater management programmes in the river basins.

ƒ Investigating cases of pollution event and providing effective corrective measures - The information collected may then be used to warn other users of the particular water body about any potential hazard.

ƒ Water quality levels exceeding the ambient standard for specific parameters will be transmitted real-time to DOE.

ƒ Imme diat e inspecti on will be cond uct ed at suspect ed sit es.

ƒ Continuous monitoring is vital for early detection of pollution influx. In 2006 – 21 incidences of distinctive pollution influx were observed.

28 DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT

TYPES OF WATER QUALITY MONITORING STATION

(a) Baseline stations – located upstream of the catchments / basin, undlddeveloped area or miiinimum actiiiivities.

(b) Ambient stations – far away, downstream from point/non-point pollution sources. Generally indicates the actual quality of river water.

(c) Impact stations - for enforcement purposes (not included in WQI calculation)

29 DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT

EVALUATION OF WATER QUALITY DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT EVALUATION OF WATER QUALITY

„ Using Water Quality Index (WQI).

„ WQI -a metho d that com bined numerous water quality parameters into one concise and objective value representing the state of water quality trends in a river.

„ The WQI can be defined as a number on a scale from 0 to 100 that is used to show the water quality.

31 DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT WATER QUALITY INDEX (WQI) Water Pollution Index -comppp;uted based on 6 main parameters ;-

(i) Total Suspended Solids – as a measure of suspended particulate in rivers;

(ii) Biochemical Oxygen Demand – as a measure of organic pollillution resu lilting from agro-bdbased and other industries;

(iii) Ammoniacal Nitrogen – as a measure of organic pollution from sewage and animal waste; sewage (human and livestock)

32 DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT

(iv) Chemical Oxygen Demand – as a measure of chemical pollution;

(v) Dissolved Oxygen - construction / mining; DO level should not be below 1ppm.

(vi) pH – measures the amount of acid in water. pH level of 5.5 and lower are particularly at risk

33 DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT WATER QUALITY INDEX

WQI = ( 0.22 x SIDO ) + [ 0.19 x SIBOD ] + [ 0.16 x SICOD ] + [005.15 x SIAN ] + [ 006.16 x SSSSISS] + [ 0.12 x SSpIpH ]

NATIONAL WATER QUALITY STANDARDS (NWQS) (MALAYSIA) DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT

ƒ NWQS used for classification of rivers or river segments based on 5 classes of water quality

ƒ NWQS helps DOE to identify problem areas & develop appropriate strategies for water quality management.

37 DEPARTMENT OF ENVIRONMENT MINISTRYMinistry OF NATURAL of Natural RESOURCESResources & Environment & ENVIRONMENT CLASSIFICATION River water quality is classified into 6 classes according to the beneficial uses of the river. CLASS USES Class I Conservation of natural environment Water Supply 1 – practically no treatment necessary Fishery – very sensitive aquatic species Class IIA Water Supply II – conventional treatment required Fishery II – sensitive aquatic species Class IIB Recreational use with body contact Class III Water supply III – extensive treatment required Fishery III – common, of economic value, and tolerance species; livestock drinking Class IV Irrigation

DATA PROCESSING

„ About 5,256 samples were taken annually , generating over 157,600 water quality data each year.

„ Data processed and used to calculate Water Quality Index.

„ Water quality status of each river basin were determine by averaging the WQI from the total stations & sampling frequency every year.
