Note: *Unless proved otherwise by the occupier based on sampling and analysis carried out by a laboratory recognized under the Act not to contain any of the constituents mentioned in Schedule 2 to the extent of concentration limits specified therein.


TABLE A 2.6: QUALITY CRITERIA OF DRINKING WATER Prescribed by Indian Standards Institution (IS: 10500-1989) and Indian Council of Medical Research (ICMR) Standards of Bacteriological Quality

i) Water in Distribution System

a) Throughout year, 95% of samples should not contain any coliform organisms in 100 ml.

b) No sample should contain E. Coil in 100 ml.

c) No sample should contain more than 10 coilform organisms per 100 ml; and

d) Coilform organisms should not be detectable in 100 ml. of any two consecutive samples.

ii) Unpiped water supplies

Where it is impracticable to supply water to consumers through a piped distribution network and where untreated sources, such as wells, boreholes and springs which may not be naturally pure, have to be used, the requirements for piped supplies may not be attainable. In such circumstances disinfection is most desirable and considerable reliance has to be placed on sanitary inspection and not exclusively on the results of bacteriological examination.
