Based on this, an audit on groundwater resources was conducted in Konaseema district of Andhra Pradesh which is popularly known for highly fertile agricultural lands and the “Rice bowl” of Andhra Pradesh. Groundwater samples were collected from three different areas representing irrigation, aquaculture and domestic purposes during the pre monsoon and post monsoon seasons of 2021, 2024 and assessed the availability, quality.

The groundwater samples collected were analysed for certain water quality parameters like pH, TDS, chlorides, TH, sulfate, nitrate, fluoride, calcium, potassium and magnesium. Based on test results, the water is generally suitable for irrigation, but the nitrate levels (144 mg/L), a little bit exceeded the acceptable limits for irrigation purpose along with high calcium, magnesium. The TDS (1460 mg/L), chlorides, and nitrates in drinking water and aquaculture lands were also studied for their concentrations in drinking and aquaculture farmlands. Among the various parameters tested the nitrate, calcium, magnesium, and TDS levels are more than the prescribed limits. The investigation is said to be important for knowing the over-extraction and pollution. The study highlights the need for conservation and sustainable management of groundwater resources which are limited and facing severe stress in Konaseema region of A.P., India.

摘要

This research aims to provide the necessary baseline data on groundwater recourses its quality, quantity and utilization for formulating the sustainable management strategies for the Konaseema region. Groundwater resource auditing is necessary to conserve it through a systematic approach of investigation, quantification and evaluation of its sourcing, use and discharge with a view to achieving water balance, identifying inefficiencies in its use, preventing over-exploitation, and developing strategies for its sustainable management and conservation. Based on this, an audit on groundwater resources was conducted in Konaseema district of Andhra Pradesh which is popularly known for highly fertile agricultural lands and the “Rice bowl” of Andhra Pradesh. Groundwater samples were collected from three different areas representing irrigation, aquaculture and domestic purposes during the pre monsoon and post monsoon seasons of 2021, 2024 and assessed the availability, quality. This study also evaluates water table depths, recharge rate and seasonal variations if any. The groundwater samples collected were analysed for certain water quality parameters like pH, TDS, chlorides, TH, sulfate, nitrate, fluoride, calcium, potassium and magnesium. Based on test results, the water is generally suitable for irrigation, but the nitrate levels (144 mg/L), a little bit exceeded the acceptable limits for irrigation purpose along with high calcium, magnesium. The TDS (1460 mg/L), chlorides, and nitrates in drinking water and aquaculture lands were also studied for their concentrations in drinking and aquaculture farmlands. Among the various parameters tested the nitrate, calcium, magnesium, and TDS levels are more than the prescribed limits. The investigation is said to be important for knowing the over-extraction and pollution. The study highlights the need for conservation and sustainable management of groundwater resources which are limited and facing severe stress in Konaseema region of A.P., India.
