How much do we know about the groundwater quality and its impact on Brazilian society today?

Abstract: Groundwater is an essential resource for society and the environment in Brazil. More than 557 m3/s (17.5 km3/y) are extracted through 2.5 million wells to meet demand in cities and the countryside, generating an economy of R$ 56 billion per year (US$ 14 billion/year). The aquifer has a remarkable function in the hydrological cycle because its large storage regulates the perenniality of rivers, lakes and preserves mangroves, marshes, and vegetation in dry periods. Aquifer discharges maintain between 24% (annual… Show more

“…Likewise, groundwater degradation is also a current issue. Hirata & Suhogusoff (2019) highlighted that aquifers have remarkable functions in the hydrological cycle, regulating the perenniality of rivers and lakes and preserving mangroves, marshes, and vegetation in dry periods. However, there has been a growing increase in groundwater contamination with anthropic compounds such as chlorinated organic solvents, heavy metals, and nitrate.…”

“…The conservation of natural environments in areas more prone to aquifer recharge should be a priority goal in water management integration programs. According to Hirata and Suhogusoff (2019), the use of groundwater in Brazil represents only 2% of the natural recharge rate, and this resource, once preserved, is an essential element for water security in a climate change scenario.…”

“…A prime example of the importance of groundwater resources is evident in Brazil, which possesses several vast aquifers noted for their exceptional water quality [5]. Among these, the Guarani Aquifer System (GAS, Sistema Aquífero Guarani, in Portuguese) stands out as a crucial freshwater resource [6].…”
