3.11.1 The Government Regulation
References of the regulation can be listed at follows: 1
Government Regulation No. 822001 about Water Quality Management and Water Pollution Control.
2 Environmental Ministerial Decree No. 1152003 about the Guidance of Water Quality
Status Calculation. 3
Regional Regulation - West Java Province No. 32004 about Water Quality Management and Water Pollution Control.
4 Regional Regulation about Guidance of Water Quality Status Calculation.
3.11.2 River Water Quality 3.11.2.1. Parameter of the Water Quality
According to the Government Regulation PP 822001, generally the classification
of parameters of water quality is classified into 4 main groups, which are: Physics, Chemistry, Biology Microbiology and Radioactivity, the later separating chemistry
parameter into Inorganic Chemistry and Organic Chemistry.
3.11.2.2 Determination of Water Quality Parameter
The number of water quality parameters depends on the usage and class of water. There is a standard on this subject. Water Quality Standard, called BMA Baku Mutu Air
which is effectively used in West Java was based on the classification of water as the Group A, B, C, D and Group BDC as well Group CD.
3.11.2.3 Grouping of Water Quality Characteristics
Study of water quality parameters show 8 groups of parameters as follow:
37 1
Physics parameter, Anion and Cation; 2
Cation parameters, Anion and pH; 3
Anorganic parameters, Non metal 4
Biodegradable organic and Dissolved Oxygen: BOD COD; 5
Metals and Heavy metals; 6
Non pesticide Organic parameters 7
Pesticide parameters; 8
Microbiology parameter; 9
Radioactivity parameters; 10
Water flow debit.
3.11.2.4 Monitoring the Water Quality

Evaluation of Class and Status of Water 3.11.3.1
Evaluation of Water Class Status
Government Regulation No. 82 Year 2001 classifying the water into four classes’ base on the usage of water. The polluted or heavily polluted water normally classified into
the fifth class.
39
Table 9. Class of Water and the Usage PP 822001
Class Intention of Usage
First Class Drinking waters, or any other use with the similar requirements.
Second Class Service water, recreational, gardening or any other use with the similar requirements.
Third Class Fresh water aquacultures, farming, , or any other use with the similar requirements.
Fourth Class Irrigation water or any other use with the similar requirements.
Fifth Class
Lower quality than the above classes
