“…Compared to the large number of studies on surface water, few have been performed to identify and understand the process of cyanotoxin contamination in groundwater. The knowledge of groundwater cyanotoxin contamination due to microcystin infiltration from HABs polluted lake at the vicinity remains notably limited (Mohammed and Shehri, 2009;Tian et al, 2013;Yang et al, 2016). Due to lake-aquifer interaction, microcystins are likely to enter the groundwater near lakes when mass of cyanobacteria blooms occur (Yang et al, 2016).…”

“…Another contamination case of groundwater getting polluted by surface-water HABs was found in the Huai River Basin, China (Tian et al, 2013). There, Tian et al (2013) collected water samples from upstream, midstream, and a tributary of the Shaying River, ponds, and groundwater wells. Their multilinear regression analysis yielded a best-fit model relating microcystin in groundwater to that of the midstream of Shaying River.…”

“…The hydraulic connectivity of the river-aquifer system controls the spread of contaminants from the river into the aquifer, or from the aquifer into the river (Batlle-Aguilar., 2008). Likewise, microcystin can contaminate groundwater due to surface watergroundwater interaction (Mohamed and Shehri, 2009;Tian et al, 2013;Yang et al, 2016).…”

Ganming Liu and Angélica Vázquez-Ortega, Committee co-chair Cyanotoxins, which are produced and released into the surrounding water during harmful algal blooms (HABs), can severely deteriorate water quality and cause health-related issues and economic loss. HABs and cyanotoxin studies have been typically focused on the surface water domain (e.g., lakes, estuaries, and rivers), with few investigating or reporting on groundwater. This study aimed to explore whether groundwater can be contaminated by cyanotoxins (microcystins) from HABs in surface water due to surface water and groundwater interaction. Specifically, we created a 3-dimensional (3-D) MODFLOW/MT3DMS model to simulate pumping-induced reverse groundwater flow and solute transport from Lake Erie to the aquifer underneath South Bass Island in Ottawa County, Ohio. Simulation results show that, under the default setting, it took ~2 months, ~3 months and ~13 months for the water in pumping well to reach the EPA advisory levels of microcystins for detection (0.1 µg/l), infants and children (0.3 μg/l), and school-age children to adults (1.6 μg/l), respectively. Furthermore, scenario analyses showed that higher pumping rate and higher lakebed leakance would accelerate the microcystin transport to groundwater well. Higher hydraulic conductivity, interestingly, would increase the time to reach those EPA levels due to mixing and dilution effect. The 3-D model developed in this study was capable of simulating the complex surface-water and groundwater interaction and transport processes in the Great Lakes setting. As the first of its kind, this modeling study provides insight for managing coastal groundwater aquifer and resources while dealing with the threat of HABs in the Great Lakes. iv Dedicated to my father for his irreplaceable love, dedication and hard work to make me a successful person v ACKNOWLEDGMENTS First of all, I would like to thank my parents, Golam Faruque and Suchitra Chakraborty.

“…However, the effects of chronic dietary exposure to sublethal microcystins remain a concern, and the synoptic-grab-sample approach employed in the present study for spatial reconnaissance purposes is not sufficient to assess the temporally variable risk associated with fluvial cyanotoxins [61]. Microcystins have been categorized as suspected group 2B tumor promoters [62] and may be linked to elevated cancer rates [63]. These results demonstrate the need for further investigation into the occurrence, sources, and ecosystem dynamics of microcystins, as well as other cyanotoxins not assessed in the present study, in streams in the southeastern region and throughout the United States, because microcystin accumulation has been shown to adversely affect fish health [54] and is a growing concern for human and wildlife consumption [59,60].…”

Despite historical observations of potential microcystin-producing cyanobacteria (including Leptolyngbya, Phormidium, Pseudoanabaena, and Anabaena species) in 74% of headwater streams in Alabama, Georgia, South Carolina, and North Carolina (USA) from 1993 to 2011, fluvial cyanotoxin occurrence has not been systematically assessed in the southeastern United States. To begin to address this data gap, a spatial reconnaissance of fluvial microcystin concentrations was conducted in 75 wadeable streams in the Piedmont region (southeastern USA) during June 2014. Microcystins were detected using enzyme-linked immunosorbent assay (limit = 0.10 µg/L) in 39% of the streams with mean, median, and maximum detected concentrations of 0.29 µg/L, 0.11 µg/L, and 3.2 µg/L, respectively. Significant (α = 0.05) correlations were observed between June 2014 microcystin concentrations and stream flow, total nitrogen to total phosphorus ratio, and water temperature; but each of these factors explained 38% or less of the variability in fluvial microcystins across the region. Temporal microcystin variability was assessed monthly through October 2014 in 5 of the streams where microcystins were observed in June and in 1 reference location; microcystins were repeatedly detected in all but the reference stream. Although microcystin concentrations in the present study did not exceed World Health Organization recreational guidance thresholds, their widespread occurrence demonstrates the need for further investigation of possible in-stream environmental health effects as well as potential impacts on downstream lakes and reservoirs.

“…The Huaihe River Basin (HRB) is one of the most densely populated areas with a large grain production capacity, and the core ability to undertake industrial transfer. As one of the basins with the greatest human-water conflicts, the HRB has witnessed numerous serious water environmental issues, the longest treatment processes, and highest cancer incidence (Tian et al, 2013;Zhuang, 2014a, 2014b;Zhang et al, 2014). The basin has a dual water cycle and the use of water resources and the relationship between the cycle and development are complex.…”

Abstract:There have been substantial conflicts in the human-water relationship in the Huaihe River Basin (HRB). To achieve sustainable economic development without degrading the water environment in the HRB, we develop a three-dimensional water environmental supporting capacity (WESC) model based on water environmental carrying capacity (WECC), water environmental pressure (WEP), and water pollution prevention and control capacity (WPPC). Geographic information systems spatial analysis with the analytical hierarchy process method and dynamic weighted summation is applied. Several proposals for suitable locations for industry and environmental protection strategies for water were presented. The following results were obtained. (1) The spatial differences in WECC are substantial; areas with high-value WECC zones are mainly located along the main stream of the Huaihe River on the south side. WEP is generally high, with an overall low level of pollution prevention and control in the whole HRB. WPPC and WEP show high spatial overlapping due to the fact that areas with higher environmental pollution usually have high level of economic development, and thus have a strong capacity for pollution control. (2) Overall, WESC is moderate in the HRB. In particular, areas with a high WESC value only account for 56.24% of the HRB in 2010. Distinct differences in WESC also exist between areas located in the south compared with in the north of the basin, and areas alongside the downstream region compared with alongside the upstream and midstream regions. (3) Consequently, according to the guidance for industry zoning in the HRB, the areas in the south and alongside the downstream and sub-streams with a low WEP value and high WECC and WPPC, traditional industries should be developed based on strict environmental access and pollution emission standards. While for the areas along the midstream of the HRB and along the whole Yishusi River Basin, which have a high WEP value, industrial restructuring and technological upgrading are suggested. Action should be taken to limit development and protect the environment in the upstream region of the basin, which is a key source of drinking water, in the eastern route along the line of the South-to-1200 Journal of Geographical SciencesNorth Water Diversion Project, and in the ecologically fragile region alongside the basin. This will ensure good environmental functionality including subsistent provision of clean water, while at the same time satisfying the urgent need to adjust, transform, and upgrade the industrial structure.
