The use of per- and poly-fluoroalkyl substances (PFAS) in numerous industrial, commercial, and military applications has resulted in their widespread distribution in the environment. Research reports have demonstrated that PFAS are present in the atmosphere, surface water, sediment, soil, groundwater, treated wastewater, biosolids, landfill leachate, and drinking water. This presentation will briefly discuss the nature, sources, and properties of PFAS, their transport, and fate in the environment, with example case studies.
Special Seminar - Diversification of South Africa’s Water Supplies Under Conditions of Drought
Shafick Adams, Water Research Commission, Pretoria, South Africa
Please note special time
Certain parts of South Africa are experiencing drought and the country’s traditional water supplies are under stress. There is a need to unlock more water resources and drive efficiency in the use of existing supplies to ensure water security. Under a changing climate, the main input into South Africa’s water resources, rainfall, becomes more variable in time and space, which means there is a need to adjust how water resources are managed and valued. Groundwater is one example of failure to use available resources to meet growing demands and increase local resilience to drought episodes. This talk will aim to give a broad overview of the challenges and opportunities that exist to diversify South Africa’s water supply mix at a variety of scales.
The Occurrence and Fate of PFAS (Per-/Poly-Fluoroalkyl Substances) in the Environment
Desert Waters International Symposium
In many regions of the world, protecting water for natural areas isan urgent matter. There are many ideas and potential lessons to be learned from our international neighbors to help Arizona reframe the link between healthy watersheds and healthy, thriving businesses and communities.
