“…Like groundwater, HCHs, DDTs, and endosulfan were the most commonly and dominantly traced pesticides in surface water. However, drins (aldrin, dieldrin, and endrin) and heptachlor were also traced in many surface water (Arisekar et al, 2019 ; Bakore et al, 2004 ; Kumar et al, 1995 ; Maurya & Kumar, 2013 ; Nag et al, 2020 ; Sankararamakrishnan et al, 2005 ; Singh et al, 2007 ). Elevated levels of HCHs were detected in the surface waters of Nagaon (1.2–22.2 µg/L) and Dibrugarh (1.03–16.2 µg/L), Assam (Mishra & Sharma, 2011 ); Chilka lake, Odisha (0.03–6.08 µg/L) (Nag et al, 2020 ); and Swarnamukhi river, Andhra Pradesh (ND–2.97 µg/L) (Kurakalva & Aradhi, 2020 ).…”

Chemical pesticides in the hydrogeological system are a global concern as they pose a severe threat to humans and other organisms. In agriculture, around 4.12 million tonnes of pesticides were used globally in 2018, which is 50% more than in the 1990s. Various pesticides detected in the hydrogeological system of India since the 1990s have been documented and reviewed to understand the prevalence, source, history and degradation pathways. This review contributes to a better understanding of existing pesticide pollution and the state of hydrogeological resource deterioration. Small to excess levels of pesticide residues were detected in groundwater, surface water, soil, and sediments. Pesticides that were most commonly and predominantly found in the hydrogeological system were HCHs, DDTs, endosulfan, heptachlor, drins (aldrin, dieldrin, endrin), chlordane etc. β and γ-HCH isomers among HCHs, whereas p,p ′-DDT and p,p ′ - DDE among the DDTs were detected most prevalently. In many regions, pesticide residue levels in water have exceeded the maximum residue limits of WHO and BIS, while those in soils and sediments have exceeded the threshold effect level and probable effect level. Higher pesticide residues were detected in the water resources of rural agricultural areas compared to peri-urban or urban areas. A positive correlation of pesticide residues between water resources and soil has been observed in some regions, suggesting a similar contamination source. Diagnostic ratios of pesticides reveal their source, history and degradation pathways. Diagnostic ratios observed in various studies conducted in India suggest historical as well as recent use of banned pesticides. Strengthening current policies and regulations, monitoring pesticide use, changes in pesticide application practices, awareness among farmers, and the use of prominent removal techniques are necessary to tackle pesticide contamination in India.
