Human exposure to antibiotic residues in drinking water has not been well evaluated. This study is the first attempt simultaneously and efficiently identify quantify 92 filtered tap (multistage filtration at tap) (n = 36) collected from 10 areas of a large city southern China, Chinese brands bottled/barreled 30) six foreign bottled 18) obtained market. The average median concentrations all detected compounds was 182 ng/L water, 180 105 666 146 respectively. A total 58 antibiotics were 45 36...
Abstract The Himalayas are critical for supplying water ∼2 billion people who live downstream, and available is highly sensitive to climate change. role of the groundwater system in sustaining northern Himalayan rivers remains unknown, this compromises Asia's future sustainability. Here, we quantify spatiotemporal contribution river flows Yarlung Zangbo Basin (upper reaches Brahmaputra). Our results show that recharge represents ∼23% mean annual precipitation, translating into ∼30 km 3 /yr...
Over the past several decades, China has rapidly depleted groundwater storage, and lagged in managing protecting this resource. As a result, dried up rivers, land subsidence, saltwater intrusion, wetland losses are extensive. To assist with vital resource, we constructed first national-scale numerical flow model of to provide comprehensive overview understanding subsurface dynamics. The is three-dimensional 10 km by horizontal resolution five discretized vertical layers (up 1700 m below...
Driven by the need for integrated management of groundwater (GW) and surface water (SW), quantification GW–SW interactions associated contaminant transport has become increasingly important. This is due to their substantial impact on quantity quality. In this review, we provide an overview methods developed over past several decades investigate interactions. These include geophysical, hydrometric, tracer techniques, as well various modeling approaches. Different reveal valuable information...
Abstract Mountainous areas are referred to as “water towers” since they the source of water for many low‐lying communities. The hydrologic budgets these areas, which particularly susceptible climate change, typically poorly constrained. To address this, we analyzed partitioning between baseflow and mountain block recharge (MBR) using a regional groundwater model northern Qinghai‐Tibet Plateau run with multiple scenarios. We found that ~19% precipitation is recharged, approximately 35%...
Key Points Shallow groundwater (<10 m deep) of alluvial plain responds to land surface regimes and dominates seasonal water budget variations Groundwater system in mountainous upstream impacts the evapotranspiration surface‐groundwater interactions downstream sustains ecosystem by contributing vegetation growing season buffering lateral flow
Shenzhen Megacity, southern China. "Sponge City" is a Chinese concept aimed to mitigate flood risk, tackle chronic water scarcity, and improve the urban environment. It consists of combination new storage infiltration facilities distributed on large scale. The similar strategies developments already adopted in Western world. In this paper, constraints interactions between sponge facilities, landscape subsoil are identified for hilly, sub-tropic terrain. Using geomorphological zonation at...
Quantifying the temporal variation of wastewater treatment plant (WWTP) discharges is essential for water pollution control and environment protection in metropolitan areas. This study develops an ensemble machine learning (ML) model to predict from WWTPs quantify contribution extraneous (mixed precipitation infiltrated groundwater) by leveraging power ML population migration big data. The approach applied at 265 Guangdong–Hong Kong–Macao Greater Bay Area (GBA) China. major conclusions are...
ABSTRACT The study describes the hydrogeological setting of Pearl River Delta, a sub-tropical area southern China encompassing metropolises Guangzhou, Shenzhen, Hong Kong and Macau. In last 40 years, booming economy population about 60 million has increased water demand satisfied by huge system dams reservoirs. Aquifers in studied are underutilized only few recent studies have addressed characterization at local scale. Understanding groundwater dynamics Delta is important for developing...
Abstract Rising water demand for agricultural, industrial, and domestic sectors continue to stress resources worldwide. In southeastern China, coastal cities megacities typically rely on thousands of reservoirs, incurring high construction maintenance costs. However, rural areas in this region, underlain by shallow, low‐permeability bedrock due regional metamorphism, host exploitable groundwater along major tectonic fault lines. To understand dynamics these fractured aquifers, study...
Groundwater temperatures in the vicinity of a 200‐ha power plant cooling lake central Wisconsin were monitored field for 1 year, and response subsurface to seasonal changes air was simulated by means mathematical model. The lake, which has been use since May 1975, when 500‐mw electric generating unit began operation, loses water groundwater system at rate 2 × 10 4 m 3 /d. zone thermally altered is confined relatively small area hydraulically downgradient from lake. However, situated...
Abstract This paper presents a simple yet effective approach and methodology for the problem of evaluating ground‐water remedial alternatives at waste disposal site, discusses application this in case study. The attainment areas, which represent areas (outside contaminant source itself) remediation is required, are first identified. Simulation flow three dimensions, augmented by fluid particle tracking, utilized to evaluate travel times ground water through areas. mixed linear reservoir or...
ABSTRACT The impact of the use a heat pump for residential heating and cooling on ground‐water temperatures was simulated by means mathematical model which couples equations flow with those transport. A hypothetical case using data typical southern Wisconsin considered. Water pumped from recharged to sandstone aquifer two‐well system. withdrawn deep well injected into shallow during cycle system operated in reverse. After ten years operation, water had changed less than one degree centigrade...
