    IMPACT OF INDUSTRIALIZATION ON WATER QUALITY AND SOIL HEALTH IN BADDI-BAROTIWALA-NALAGARH INDUSTRIAL HUBS OF HIMACHAL PRADESH
    (2010) KHAJURIA, NEETAN; TRIPATHI, D
    ABSTRACT The present investigations entitled “Impact of industrialization on water quality and soil health in Baddi- Barotiwala-Nalagarh industrial hubs of Himachal Pradesh” was carried out in Solan district of Himachal Pradesh during the year 2008-2009. The soil, water and plant samples were collected from thirty sites of three locations. The soil samples were collected at two depths (0-15 cm and 15-30 cm) and water samples were collected from Sirsa river, Sandhouli nullha, Balad khud, borewell and tap during pre and post monsoon seasons. The pH ranged from 7.89 to 8.65 and highest was recorded in textile industry effluent and lowest in paper industry effluent. The effluents from textile andpharmaceutical industries registered maximum (4.49 dS m_1) and minimum (1.49 dS m_1) electrical conductivity, respectively. Whereas, highest TSS (2599 mg/l) and lowest TSS (169 mg/l) was recorded in effluents of chemical and paper industry, respectively, which were quite above the BIS standard limits (100 mg/l). The contents of chloride present in the effluents of industries were ranged from 496 to 645 mg/l. The BOD values varied from 1.88 to 2.41 and found to be within safer limit (30 mg/l). The highest COD (1403.00 mg/l) was registered with chemical industry and minimum (303 mg/l) in textile industry. The soils of the industrial area registered slightly acidic to slightly alkaline pH. The EC values in surface soils, during pre and post monsoon season at different sites ranged from 0.11 to 0.38 and 0.12 to 0.34 dSm_1. The organic carbon content in surface soils of different sites varied between 3.00 - 8.25 and 3.72 - 8.78 g kg_1, whereas in locations from 4.38 to 4.83 and 4.83 to 5.48 g kg_1 during pre and post monsoon season, respectively. The available N, P and K were rated as low, high and low to medium, respectively considering the critical limits of these elements. However, DTPA extractable Mn, Fe, Cu and Zn were found to be low to high, high, high and low to high in their status, respectively. Further, the content of Pb, Ni and Cd were below permissible limit of 5.00, 2.00 and 0.05 mg kg_1, respectively. Lead content in surface soils, during pre and post monsoon season of different sites ranged from 0.46 to 2.18 and 0.50 to 2.19 mg kg_1. Nickel content in different sites ranged from 0.09 to 0.62 and 0.16 to 0.65 mg kg_1 in surface soils. The cadmium content ranged from 1.00 to 1.09 and 0.02 to 0.21 mg kg_1. The concentration of Mn, Cu, Fe and Zn in plant samples ranged from 8.10 to 10.04, 0.53 to 0.86, 8.84 to 9.25 and 0.74 to 1.59 mg kg_1at different locations during pre monsoon season and ranged from 8.16 to 10.09, 0.54 to 0.92, 8.94 to 9.30 and 0.75 to 1.59 mg kg_1 during post monsoon season. The concentration of Pb was above the permissible limit. The pH of river and nullhas water ranged from 8.04 to 8.29. The EC values, irrespective of season of river and nullhas water ranged from 414.00 to 9324.00 μSiemens/cm. The corresponding values for bore well and tap water ranged from 0.40 to 1.37 dSm_1. The HCO3 - and CO32- concentration were within permissible limit. The concentration of Ca, Mg and Na in borewell and tap water ranged from 22.67 to 64.33; 8.33 to 29.00 and 17.33 to 43.00 mg/l. The BOD and COD concentration of river and nullhas water ranged from 0.54 to 203.33 and 15.33 to 527.67 mg/l. The concentration of Fe, Cu, Mn and Cd in river and nullhas water ranged from 0.51 to 1.12; 0.03 to 0.09; 0.10 to 0.35 and 0.03 to 0.10 mg/l. The microbial biomass carbon of Nalagarh, Baddi and Barotiwala in surface soils during pre and post monsoon season varied between 35.78 - 89.87; 34.16 - 108.83 and 42.93 - 128.45 mg MB-C/100g soil, respectively.
