Abstract
The present paper examines the seasonal variations in groundwater quality (Pre-monsoon & Post- Monsoon) with an emphasis on paper industry effluents from the Sirpur-Kaghaznagar area. Spatial distribution of samples from 24 sites collected during pre and post-monsoon using surfer software gives an insight of important parameters such as pH, EC, TDS, BOD, COD, DO, Ca+, Mg2+, Na+, F, Cl-, NO3,- SO42- and TH to be significantly elevated beyond the acceptable and permissible levels prescribed by BIS limits. Also, the Physico-chemical analysis of paper mill effluent collected from 12 different sites revealed that parameters such as pH, EC, TDS, BOD, COD, Alkalinity, SO42-, Cu, and Fe were beyond the BIS permissible limits for effluent discharge and designated a profound negative impact on groundwater quality and lead us to conclude that the overall quality is deteriorated due to the influx of paper industry effluents.
Highlights
Water is a prime resource, its effective use and management are considered very important for the future demands of the increasing population
The collected effluent samples were stored at - 40C to stop the chemical reactions and the samples were characterized for its chemical properties by adopting standard protocols
The results indicated that the values of Cd, Cu and Fe were found higher than the prescribed limits of BIS standards for irrigation water which reflect the toxic nature of paper mill effluents
Summary
Water is a prime resource, its effective use and management are considered very important for the future demands of the increasing population. Industry which consumes large quantities of water for processing the pulp and paper. It consumes about 250-300 m3 of water per ton of paper produced and the estimated production capacity soon will be huge. Considering the long term adverse effects of pulp and paper industry, the research work was begun to know the exact status of water quality due to the influence of paper mill effluents surrounding area of kaghaznagar, Telangana. Study Area Sirpur-Kaghaznagar located in the eastern Telangana being part of Adilabad district is a small town. It lies between 19.33330 N-79.48330 E (Fig-1) with an average elevation of the area is 174 meters (574 feet). Water level difference observed during pre-monsoon was 0.22-31.25 m below the ground and post-monsoon recorded 0.3-17.15 m
