Summary: Long datasets for groundwater are of great value in environmental monitoring, but there is a global scarcity of such datasets, especially those that extend beyond 30 years. This article lists and illustrates the benefits of long-term data in hydrogeological investigations and groundwater management activities, while discussing the reasons for their scarcity.

Summary: Groundwater sustainability faces challenges due to the disparity between legal and scientific understanding, as well as the lack of attention to regulatory design in the literature. This paper aims to utilize the scientific characteristics of groundwater to inform regulatory design. The article describes seven groundwater characteristics and applies them to a case study in British Columbia, Canada, highlighting the failure of regulatory design even in a well-resourced jurisdiction. The recommendations drawn from this study can improve regulatory design and have implications for states with customary water entitlements.

Summary: Integrated Water Resource Management (IWRM) is increasingly being used to resolve water-related conflicts globally. The Philippine government has been updating its water policy and regulatory framework to promote IWRM. This study aims to identify and rank the key elements affecting IWRM changes at the subnational level in Palawan Province.

Summary: The paper provides an overview of hazardous factors related to groundwater and gives specific variables for quantifying these hazards. It presents and discusses appropriate hydraulic groundwater flow models and their suitability for modeling individual typical problems and quantifying hazards. The use of models and the application of CAD and GIS tools for data pre- and post-processing are briefly mentioned and demonstrated using examples of typical practical situations.

Summary: This study introduces a new method that combines geodetic and in situ groundwater data to estimate groundwater storage change in the Parowan Valley. The results show that both fine- and coarse-grained layers contribute equally to the total groundwater storage loss, but fine-grained layers dominate in confined aquifers. These findings have important implications for understanding the source of groundwater in depleting aquifer systems.

Summary: Groundwater systems are commonly classified as renewable or non-renewable, but this definition is challenged because it depends on how the groundwater is being used. We propose more accurate definitions for renewable groundwater use based on hydraulic principles, and suggest that a matrix framework can be used to characterize different types of groundwater use. This understanding of renewable groundwater use can contribute to sustainable groundwater management. Rating: 8/10.

Summary: Since 1900, Semarang City has been meeting its industrial water needs by pumping groundwater, leading to land subsidence due to excessive groundwater exploitation. A numerical study was conducted to model the temporal and spatial evolution of groundwater table under excess abstraction, aiming to develop a groundwater management strategy for sustainability. The results show that proper groundwater control measures can restore the groundwater level in Semarang City and ensure the sustainability of groundwater resources.

Summary: Sustainable use of groundwater while maintaining economic and social development is a major challenge. The implementation of wellhead protection areas (WHPA) has been used to overcome this challenge. This study compares different methods for delineating WHPAs and analyzes their reliability in different scenarios. The results suggest that all methods produce satisfactory results for a single well, but uncertainties and reduced precision arise as the time-of-travel increases and during multiple well pumping due to three-dimensional flow complexities.

Summary: Management of groundwater resources is hindered by a lack of data and understanding of aquifer behavior. The scarcity of groundwater data in developing countries often leads to ineffective management or abandonment of aquifers. Traditional methods of groundwater quality protection, such as prescribed separation distances, fail to consider internal and boundary characteristics that impact response rates and contamination. A study on the karst aquifer system in Lusaka found that pit latrines are a significant source and pathway of groundwater contamination. Rapid movement of dye tracers in groundwater highlights the inefficiency of regulatory separation distances in reducing contamination. Policy focus should shift to robust sanitation solutions for low-income communities.

Summary: Isotopic signatures of anthropogenic sulfate sources were investigated to assess the origin of groundwater contaminants in the Upper Silesian urban area. Significant discrepancies were found in the delta S-34 and delta O-18 values of sulfate derived from different contamination sources. Isotopic analyses confirmed the impact of urbanized and industrialized areas on surface water pollution and its potential influence on groundwater contamination.

Summary: The increase in population has led to a growing demand for groundwater resources, particularly in agriculture, in Udaipur district, India. This study assessed the groundwater reserves in the area and found that there is over-exploitation of the resource. However, there are enough static groundwater reserves to sustain during drought periods.

Summary: The Guarani Aquifer System is a massive groundwater body underlying large areas of Brazil, Paraguay, Uruguay and Argentina, with mainly weakly-cemented sandstones formed during the Triassic-Jurassic period, and is totally storage-dominated. Despite its vast regional freshwater storage, recharge is minimal and groundwater flow rates are extremely slow, with some parts of São Paulo State in Brazil having groundwater older than 730,000 years BP.

Summary: Understanding and managing the impact of return flows to shallow groundwater from irrigated cultivation of permeable soils have been seriously neglected, which does not figure in practical guidance to farmers on soil and water management. This assessment provides examples of serious groundwater salinization and identifies key factors involved, suggesting measures that can help to mitigate the problem.
