Abstract The movement of water, matter, organisms, and energy can be altered substantially at ecohydrological interfaces, the dynamic transition zones that often develop within ecotones or boundaries between adjacent ecosystems. Interdisciplinary research over last two decades has indicated interfaces are “hot spots” ecological, biogeochemical, hydrological processes may provide refuge for biota during extreme events. Ecohydrological have significant impact on global biogeochemical cycles,...
Abstract Estimated annual water availability per person in 2025 is likely to result at least 400f the world’s 7.2 billion people facing serious problems with obtaining freshwater for agriculture, industry or human health (Gleick 2001). To meet present and future needs currently available surface groundwater resources, while same time preserving terrestrial aquatic ecosystems, will require a sustainable approach managing water. This paper discusses importance of resources industrialized...
The sustainability of rural groundwater supply infrastructure, primarily boreholes fitted with hand pumps, remains a challenge. This study evaluates whether coverage targets set out within the Millennium Development Goals (MDG) inadvertently increased challenge to sustainably manage water infrastructure. Furthermore, drive towards decentralised service delivery contributes financial burden assets. A sample size 14,943 Afridev pump was extracted from comprehensive live data 68,984 points...
The current occurrence of nitrate in the major aquifers England and Wales is presented evidence for denitrification critically reviewed. Denitrification principal attenuation process subsurface its potential mitigating widespread inputs considered. study focuses on three most important aquifers: Cretaceous Chalk, Permo-Triassic Sandstone Jurassic Limestone. Elevated ground-water concentrations are shown to be continue rise, with leaching from soils predicted remain significant. Some 60%...
Countries located on the East African Rift System (EARS) are vulnerable to fluoride in their groundwater; a vulnerability for developing country of Malawi at southern rift periphery that is not well characterised. Groundwater occurrence documented here better understand and manage risks posed. Available literature Gov't archive data spanning some fifty years have been collated augmented by our own 2016–18 surveys groundwater quality Southern Malawi, targeting deep-sourced springs. In total,...
This paper describes the proceedings of a Special Session on Natural Source Zone Depletion (NSZD) at AquaConSoil conference, held virtually in June 2021. It spans research across Europe, United States America and Australia. NSZD has been described as ‘combination processes that reduce mass LNAPL light non-aqueous phase liquid) subsurface’. investigations have focused range hydrocarbon products, such gasoline, diesel, jet fuel, well crude oil. Key include aerobic biodegradation, fermentation...
Pumped groundwater sampling evaluations often assume that horizontal head gradients predominate and the sample comprises an average of water quality variation over well screen interval weighted towards contributing zones higher hydraulic conductivity (a permeability-weighted sample). However, pumping rate used during may not always be sufficient to overcome vertical flows in wells driven by ambient gradients. Such are reported with screens between 3 10m length where lower rates more likely...
The concept of Stranded Assets has been used for nearly 50 years across many sectors, most recently it a focus investment portfolios in light the possible impacts climate change. However, to date there no in-depth determination impact rural water supply, despite international development targets from Rio, through Millennium Development Goals (MDGs), and now Sustainable (SDGs). limiting factor carrying out such an assessment is requirement full detailed asset register recording all supplies...
