Estimar os valores de recarga das águas subterrâneas é importante para entender a dinâmica de sistemas aquíferos perturbados por forçantes climatológicas e pelo uso e ocupação da terra. Este trabalho estimou as taxas de recarga das águas subterrâneas pelo método da variação da superfície livre em área do Sistema Aquífero Bauru (SAB) para a Estação Ecológica e na Floresta Estadual de Santa Barbara nos anos hidrológicos 2014/2015 e 2015/2016. Durante esse período a região passou por dois períodos climáticos distintos: um ano considerado normal (com taxas de precipitação em torno da média histórica dos últimos 30 anos) seguido de um ano com a presença do fenômeno ENOS (El Niño Oscilação Sul) aumentando a precipitação em 35,44% quando comparado ao ano anterior. Os resultados demonstraram, apoiados na espacialização do fenômeno pela área estudada, que apesar das diferenças nas taxas de precipitação, o percentual de recarga foi o mesmo para os dois anos, não evidenciando diferenças entre as áreas com vegetação de Cerrado e reflorestamentos com espécies exóticas como Pinus e Eucalipto.

“…The slope greater than 8 in all samples implies less or no evaporation effect (Clark and Firtz, 1997) and intercept (dexcess) value greater than 10‰ in most of the samples suggests that the probable input to the recharge is recycling water vapor contributed by the possible surface flows (Fynn, 2016). The wide variation in isotopic signature (ä18O: -10.16‰ to -4.74‰) might be the reflection of multiple recharge source (Keesari et al, 2017). Dominance of coarse particles increasing towards the northern part reveals the good aquifer sequence in the northern zone and hence proves the best recharge area.…”

The Sunsari and the Morang Districts confine the eastern region of the Koshi River and are considered as a huge potential of groundwater zones. The study mainly focuses on the concept of delineation of recharge source of groundwater and connection between aquifer system through isotopic analysis. Altogether 33 samples are collected from surface and groundwater for the isotopic analysis. Majority of the samples of flowing artesian wells are encountered under the range of -7.03‰ to -6.53‰. The shallow aquifers fall under the range of -5.94‰. to -5.34‰ and deep aquifers fall over a wide range of -7.13 ‰. to -6.53‰ for δ18O. Clustering of samples from isotopic analysis gives idea of surface water and groundwater interconnection along with the recharge source identification. Isotopic variation of majority of samples ranges from -7.34‰ to -4.74‰ while depleted value for δ18O is -10.16‰ in shallow aquifer of Jamungachhi, which indicates that the recharge source is precipitation at higher elevation. The d excess (greater than 10‰) concluded that the aquifer system in the study area is complex and recharged from various sources. The range of enrichment is measured as 2.6‰< 1.96‰<1.87‰<1.55‰ for shallow aquifers, rivers, deep aquifers and flowing artesian well. The significant increase in coarse particle towards the northern part reveals the good aquifer sequence in the northern zone and proves the best recharge area. The overall aquifer system in the study area is complex and recharged from various sources. Most of the aquifers are recharged from the river sand precipitation at higher altitude.

“…High levels of Na + in the groundwater are related to the aquifer recharge from lateral limestone formations or clays by cation exchanges or silicate weathering [ 63 ]. The domination of cations found in the studied area shows that the sources are silicate weathering and agricultural runoff [ 64 , 65 ]. The concentration of Ca 2+ ranged between 0.05 mg/L and 82.65 mg/L.…”

Rapid urbanization and industrial development in the Langat Basin has disturbed the groundwater quality. The populations’ reliance on groundwater sources may induce possible risks to human health such as cancer and endocrine dysfunction. This study aims to determine the groundwater quality of an urbanized basin through 24 studied hydrochemical parameters from 45 groundwater samples obtained from 15 different sampling stations by employing integrated multivariate analysis. The abundance of the major ions was in the following order: bicarbonate (HCO3−) > chloride (Cl−) > sodium (Na+) > sulphate (SO42−) > calcium (Ca2+) > potassium (K+) > magnesium (Mg2+). Heavy metal dominance was in the following order: Fe > Mn > Zn > As > Hg > Pb > Ni > Cu > Cd > Se > Sr. Classification of the groundwater facies indicated that the studied groundwater belongs to the Na-Cl with saline water type and Na-HCO3 with mix water type characteristics. The saline water type characteristics are derived from agricultural activities, while the mixed water types occur from water–rock interaction. Multivariate analysis performance suggests that industrial, agricultural, and weathering activities have contributed to groundwater contamination. The study will help in the understanding of the groundwater quality issue and serve as a reference for other basins with similar characteristics.
