TITLE:

GROUNDWATER AT RISK: METHODS FOR ASSESSING NITRATE CONTAMINATION IN ARID REGIONS

KEY WORDS:

Water insecurity; Water quality; Aquifers; Watershed; DRASTIC

PAGES: 40
BIG AREA: Engenharias
AREA: Engenharia Sanitária
SUMMARY:

Growing concern over nitrate contamination in groundwater has driven the application of different methodological approaches for evaluating vulnerability and contamination risk, as well as the potential associated health hazards. Research focused on this issue in hyper-arid, arid, and semi-arid environments—regions highly dependent on groundwater resources—remains recent and incipient in the global context. Therefore, this study conducted a comprehensive review of the topic by analyzing 461 articles obtained from the Web of Science database and deepening the investigation within the context of arid regions through the selection and analysis of 44 articles. The results showed that most studies have an investigative character, conducted mainly in physical-natural units, especially watersheds and aquifers, with emphasis on intrinsic physical parameters used in index models. However, hydrodynamic and hydrochemical variables are less explored. Furthermore, aspects such as seasonality, contaminant dynamics, groundwater-level fluctuations, and artificial aquifer recharge are still approached in a limited manner. In light of this, it is recommended that studies deepen the analysis of applied parameters and adopt integrated approaches that consider local specificities in order to support the sustainable management of groundwater resources in areas vulnerable to nitrate contamination.
