In 2001 NEERI collected water samples from Clean Water Reservoirs of Jaipur. Testing of physio-chemicals parameters was done. The water samples were found to high concentration of TDS, hardness, alkalinity, Calcium and Magnesium . The average values of the before mentioned parameters have been graphically presented for the 25 CWRs.The full article is available at http://www.indiawaterportal.org/post/39393.

2.  In 2001, NEERI collected water samples from 25 Clean Water
Reservoirs of the city.
 Samples were collected for few days in three seasons ( summer,
winter, monsoon).
 Testing of physio- chemical parameters as mentioned in BIS:10500
were carried out.
 No bacteriological parameter was tested at CWR level.

3.  The samples were found to have high concentration of TDS,
hardness, alkalinity, Ca and Mg.
 In the subsequent slides graphs of the average levels of the above
mentioned parameters are shown.
 The red line indicates the maximum limit of the parameters as given
in BIS:10500 drinking water standards.
