  WATER QUALITY STANDARDS FOR COASTAL WATERS MARINE OUTFALLS.
  In a coastal segment marine water is subjected to several types of uses. Depending of the types of uses and activities, water quality criteria have been specified to determine its suitability for a particular purpose. Among the various types of uses there is one use that demands highest level of water quality/purity and that is termed a “designated best use” in that stretch of the coastal segment. Based on this, primary water quality criteria have been specified for following five designated best uses:-
   
  Class Designated best use
  SW-1(See Table 1.1) Salt pans, Shell fishing, Mari culture and Ecologically Sensitive Zone
  SW-1I(See Table 1.2) Bathing, Contact Water Sports and Commercial fishing.
  SW-1II(See Table 1.3) Industrial cooling, Recreation (non-contact) and Aesthetics
  SW-1V(See Table 1.4) Harbour
  SW-V(See Table 1.3) Navigation and Controller Waste Disposal
     
  The Standard along with rationale/ remarks for various parameters for different designated best uses, given in Table 1.1 to 1.5
       
TABLE 1.1 PRIMARY WATER QUALITY CRETERIA FOR CLASS SW-1 WATERS (For Salt pans, Shell fishing, Mari culture and Ecologically Sensitive Zone)
 
S.No. Parameter Standards Rationale/Remarks
1. 2. 3. 4.
1. pH range 6.5-8.5 General broad range, conductive for propagation of aquatic lives is given. Value largely dependant upon soil-water interaction.
2. Dissolved Oxygen 5.0 mg/l or 60 percent saturation value whichever is higher Not less than 3.5 mg/l at any time of the year for protection of aquatic lives.
3. Colour and Odour No noticeable color or offensive odour. Specially caused by chemical compound like creosols, phenols, naptha pyridine benzene, toluene etc. causing visible coloration of salt crystal and fainting fish flesh.
4. Floating Matters Nothing obnoxious or detrimental for use purpose Surfactants should not exceed an upper limit of 1.0 mg/l and the concentratic not to cause any visible foam.
5. Suspended Solids None from sewage or industrial waste origin Settle able inert matters not in such concentration that would impair any usages specially assigned to this class.
6. Oil and Grease (including Petroleum Products) 0.1 mg/l Concentration should not exceed 0.1 mg/l as because it has effect on fish eggs and larvae.
7. Heavy Metals: Mercury (as Hg) Lead (as Pb) Cadmium (as Cb) 0.001 mg/l 0.001 mg/l 0.01 mg/l Values depend on: (i)        Concentration in salt, fish and shell fish. (ii)       Average per capita consumption per day. (iii)     Minimum ingestion rate that induces symptoms of resulting diseases.
Note: SW-1 is desirable to be safe and relatively free from hazardous chemicals like pesticides, heavy metals and radio nuclide concentrations. Their combined (synergistic or antagonistic) effects on health and aquatic lives are not yet clearly known. These chemicals undergo bio-accumulation, magnification and transfer to human and other animals through food chain. In areas where fisheries, salt pans are the governing considerations, and presence of such chemicals apprehended/reported, bioassay test should be performed following appropriate methods for the purpose of setting case specific limits.
