Abstract
Present study entitled, “Characterization of ground water quality of Pataudi and Farukh
Nagar blocks of Gurgaon district”, to quantify and map water for general quality for irrigation
and having nitrate and fluoride and to assess the effect of different quality waters on
physico-chemical properties of soils in respective blocks, was undertaken. For this purpose, 261
and 171 tube-well random water samples from Pataudi and Farukh Nagar blocks respectively
were collected. On the basis of water analysis, soil samples from Pataudi and Farukh Nagar
blocks were collected and analyzed for their physical and chemical properties.
pH, EC, SAR and RSC in irrigation waters of Pataudi varied from 7.10-9.30,
0.52-10.71 (dS m-1), 0.30-26.62 (mM L-1)½ and Nil-15.20 (me L-1), respectively. Likewise corresponding values of water quality for Farukh Nagar varied from 7.20-9.05, 0.45-13.40 dS
m-1, 0.42-25.56 (mM L-1)½ and Nil-10.25 me L-1, respectively. Cations were in the order: Na+
> Mg+2 > Ca+2 > K+ while anions were HCO3- > Cl- > SO4-2 >CO3-2 upto EC 2 dS m-1 and
thereafter the trend was Cl- > HCO3- >SO4-2 >CO3-2 in both the blocks. As per Manchanda
(1976) classification, 52.9, 13.0, 5.4, 18.0 and 10.7 per cent waters of Pataudi block were
classified under good, marginal, saline, sodic and saline-sodic categories, respectively. Likewise
60.2, 11.1, 9.4, 8.2 and 11.1 per cent of the respective under ground waters were found in the
corresponding category in Farukh Nagar block. As per AICRP (1989) classification, 42.5, 11.1,
5.4, 11.5, 13.8, 7.7 and 8.0 per cent waters of Pataudi block were classified under good,
marginally saline, saline, high SAR saline, marginally alkali, alkali and highly alkali categories,
respectively. Likewise 40.2, 8.2, 9.4, 11.1, 13.5, 12.9 and 4.7 per cent of the respective under
ground waters were found in the corresponding categories in Farukh Nagar block. The use of
poor quality water resulted salt accumulation in both the surface (0-15 cm) and sub surface
(15-30 cm) layers. Mostly highest ECe and SARe were observed in the upper layer (0-15 cm) of
soil in both blocks. In Pataudi, out of 261 samples, 25.7% samples contained nitrate and 39.5%
samples had fluoride beyond permissible limits. For Farukh Nagar, these values were 32.8 and
37.4 per cent, respectively.
