The complex and often sensitive relationships between human activities and freshwater resources have been highlighted during the COVID-19 pandemic, providing unique insights into how humans interact with freshwater resources, both in terms of impacts and dependencies on these systems. In particular, mandated lockdowns in several areas of the world have resulted in relatively rapid improvements in water quality due to limited human activity, suggesting the resilience of natural systems. However, the need and challenges of providing clean water in both rural and urban areas were also highlighted by restrictions associated with the COVID-19 pandemic, with limited access to sanitation likely increasing the transmission of COVID-19. In some areas, fisheries experienced increased pressures as food distribution systems and local economies were disrupted. Moreover, ongoing changes in climate, particularly related to precipitation, have also likely exacerbated water-related issues during the pandemic. The combination of COVID-19 restrictions, regional climatic variability, and varying levels of social and economic stability suggest the need for preemptive approaches to ensure water availability and access to freshwater resources in all areas of the world in the coming decades.

Seasonal and spatial trends, and relationships between hydroclimatologic variables were analyzed to identify opportunities for regional implementation of water management strategies under climate change in the Atlantic Coast of the United States (ACUS). For this, projected climate-induced changes (RCP 8.5) in seasonal streamflow and water temperature in ACUS watersheds by the middle and end of the century were assessed. Changes in hydroclimatologic variables suggested spatial trends clearly differentiated by seasons. Northern and central watersheds are projected to experience the most dramatic seasonal streamflow and water temperature changes in winter and summer, while southern watersheds presented the largest increase of streamflow in fall, and water temperature changes greater than 3°C for all seasons. These similarities and contrasts between ACUS watersheds’ hydrologic responses provide an opportunity for regional management of climate induced impacts on water resources.

The global population has grown significantly over the past years. Quality of life is generally increased along with the higher need for energy and water, alongside the proliferation of environmental issues to be resolved. High-quality drinking water is essential for day-to-day living, for food production, for better living standards, for the somehow neglected nature and the industry. The need for water is increasing rapidly and freshwater resources cannot deal with all the requirements. Water is not accessible to all as a natural, self-renewable low-cost resource. The drought in various regions on earth followed by desertification and the gravitation of populations towards this essence of life is calling for different considerations in terms of economic and social effects.

Solutions for clean water supply in remote locations are urgently required. Water is needed in locations where agriculture is the basis for life. The development of low-cost water sources could be the basis for increased industry toward a thirsty world. It is a global question of the same type of the usage of diminishing natural energy resources and solutions for environmental problems. The future of humankind depends on proper answers related to these questions, together with the questions of global peace and human wealth on earth. Sharing water expertise and industry best practices between counties worldwide would help fight water security challenges. It is not enough, however, to produce low-cost water. It is also important to educate people towards proper usage of water that will improve their way of life.

This presentation summarizes the experience gained in Israel including main techniques for utilizing alternative water sources like brackish water, seawater, and domestic wastewater. Explanations regarding the physics and chemistry of the different processes are given. Membrane-based technologies are discussed with emphasis given to their energy consumption and cost as well as potential and actual environmental impacts.

Increasing salinity in freshwaters (freshwater salinization) is well documented in surface waterbodies, particularly in urban and high latitude environments where road salt application and other human-related activities increase major ion content in natural water. However, the mechanisms, pathways, and timescales of salinization across multiple hydrologic reservoirs (surface water, soil water, and groundwater) in the critical zone (the thin, life-supporting layer of Earth’s surface from the tops of the trees to the bottom of the groundwater) are understudied. Karst systems, which feature sinkholes, caves, and springs, may be more vulnerable to freshwater salinization than other landscapes because of highly permeable and deep critical zones. We therefore interpret 25 years of chemical data for soil, soil porewater, and groundwater and use laboratory soil experiments to understand processes that enhance salinity in these critical zones. Road salt contaminants (Na+ and Cl-) can move through soil in two ways. Soil porewater movement can slow ion transport to < 1.5 cm/day and is the main conveyance mechanism for Cl-. Soil cation exchange further slows Na+ movement by 3-5 months, a process accompanied by base cation and trace element release to porewater. Deicer-related ion concentrations in soil are highest within 25 cm of the road, and ion pulses decrease with distance. Delivery of road salt pollution to the aquifer occurs on two timescales. Ions move rapidly into the karst during the winter through sinkholes and other conduits. Over seasonal and decadal timescales, Na+ and Cl- accumulate in the aquifer as water moves slowly through diffuse pathways and when Na+ is retained and subsequently released via cation exchange. Our findings show that freshwater salinization in critical zones occurs both rapidly and over long timescales as contaminants like road salt move at different rates through the system and interact with the substrate along the flow path.

Reservoirs are vital components of our nation’s water-resources infrastructure; however, many reservoirs across the nation are slowly being filled with sediment, which reduces their effectiveness, increases maintenance costs, and compromises dam safety. The U.S. Army Corps of Engineers (USACE) has developed the Reservoir Sedimentation Information (RSI) database to help evaluate reservoir aggradation trends, life expectancy, and vulnerabilities to climate change. The focus of this study is to develop methods to estimate reservoir sedimentation rates using the RSI data and various supplemental resources.  A composite dataset was developed with RSI capacity data from 797 surveys (from 184 total reservoirs) and 29 other geospatial and climate parameters. Ten models for predicting capacity loss were developed from the composite dataset. These models consisted of a multilinear power regression equation (ordinary least squares method), four supervised machine learning algorithms, four deep neural network (machine learning) algorithms, and an artificial intelligence algorithm (AI).  This presentation will highlight methods used to derive supplemental geospatial parameters, methods used to develop prediction models, and results from capacity loss prediction models.

Harmful algal blooms (HAB) are a significant problem in drinking water sources globally and in the U.S. due to the toxic cyanotoxins they release. The most common freshwater cyanotoxins include microcystins, cylindrospermopsin, anatoxin-a and saxitoxins. Treatment options for cyanotoxins by water utilities include both chemical oxidation and powdered activated carbon. Unfortunately, the use of chemical oxidants is highly complex and depends widely on the type of oxidant (e.g., chlorine, monochloramine, ozone, permanganate, or chlorine dioxide), on the type of cyanotoxins and their variants present in the water source, and varies with water quality parameters at the source and through the treatment process (e.g. pH and temperature). In the United States, with no standard treatment regulations yet in place, water utilities are left to set their own standard operating procedures and modify their treatment approach to address cyanobacteria and cyanotoxins removal. In 2016, the freely downloadable Hazen-Adams CyanoTOX Tool was developed to assist water utilities in planning and real-time control of cyanotoxin events in water sources. This presentation will address these topics as well as the on-going research at 91Å®Éñ to support the next version of CyanoTOX.

Nutrient is a key factor for the growth of primary producers in the aquatic ecosystems. Many studies have been focusing on nutrients like nitrogen and phosphorus, while little attention has been paid to the organic micronutrients like vitamins, which are also essential factors for the growth of organisms. This presentation discusses the ecological effect of vitamin B1 (thiamine), one of vital growth factors for all living cells, on the primary producers in the aquatic ecosystems.
