Summary
A new database, GWDBrazil, consolidates over 351,000 groundwater well records for Brazil. This resource supports sustainable water management by providing harmonized, quality-controlled data for large-scale studies.
Area of Science:
- Hydrology
- Hydrogeology
- Environmental Science
Background:
- Spatiotemporal in-situ groundwater-level measurements are crucial for sustainable water management.
- Limited access to harmonized, quality-controlled groundwater data has historically impeded large-scale hydrological studies in Brazil.
Purpose of the Study:
- To present the Groundwater Well Database for Brazil (GWDBrazil), a consolidated and standardized dataset of groundwater well information.
- To provide a comprehensive resource supporting integrated surface water and groundwater management in Brazil.
Main Methods:
- Consolidation and standardization of data from over 351,000 wells, with records spanning 1900 to 2024.
- Inclusion of approximately 450 wells with continuous daily monitoring data (2010-2024).
- Application of cross-verification steps to ensure data accuracy and reliability.
Main Results:
- The GWDBrazil dataset includes well location, depth, purpose, distance to nearest river, and aquifer information.
- Data is available in both tabular and vector point formats.
- The database provides essential information for integrated water resource management.
Conclusions:
- GWDBrazil serves as a valuable resource for researchers, policymakers, and stakeholders involved in water management in Brazil.
- The dataset facilitates comprehensive water management strategies by offering standardized and accurate groundwater information.
- Improved data accessibility through GWDBrazil is expected to advance groundwater research and sustainable water resource utilization in Brazil.

02:34Water and Mineral Acquisition
35.3K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as:
