At Home and Abroad: The Study Room in Exiles in parts per billion (ppb) or even lower. It has been found that mostly two herbicides, Alachlor and Atrazine, and one insecticide, Malathion, are found in significant levels in groundwater of India. In lower Ganges basin, Malathion concentration is much higher than the permissible limit. Signific观察 发表于 2025-3-23 22:23:55

Fluoride is found as the major contaminant in all the three regions as F varied from 1.9 to 4.5 mg/L in Jaisalmer, while in Pokhran and Bhatinda it has varied between 1.1 and 6.1d-limonene 发表于 2025-3-24 05:31:53
Overview of the Groundwater of South Asiaal anthropogenic activities, particularly irrigation (accounts for >80% of the groundwater withdrawal), lead to groundwater depletion in most of areas within the region. Varying precipitation rates and subsurface hydraulic condition are providing more challenges to groundwater governance. Widespreadincarcerate 发表于 2025-3-24 09:05:12
Groundwater Availability in the Kabul Basin, Afghanistanbeen used to estimate water resources in the basin, the potential effects of increased groundwater withdrawals, and potential climate-induced changes to recharge in the basin. Simulated increases in groundwater withdrawals will affect areas of the basin with the greatest population growth, while a c灯丝 发表于 2025-3-24 13:04:19
Estimating Present-Day Groundwater Recharge Rates in Indianergistically influence high recharge rates. Most of the regions on the central and southern study areas exhibit lower recharge rates (<200 mm/year). Magnitude of estimated recharge rates was quite similar from different approaches of groundwater recharge calculation; however, inconsistency in the oPalpitation 发表于 2025-3-24 15:08:12
Groundwater of Hard Rock Aquifers of Indiafrom 0.9 to 1.8 cubic metre per hour (m./h). The cumulative yield from the weathered zone and underlying saprolite may range up to 9–10.8 m./h. The yielding fractured zones are mostly encountered within 100–150 m depth and could occur deeper also, as observed in Karnataka State in southern part of Ienchant 发表于 2025-3-24 19:59:00
