Groundwater management

This Technology Transfer Advances Sri Lanka's

• Nationally Determined Contribution and its adaptation targets to build climate resilience of sectors such as health, water management, urban infrastructure and settlement, which are vulnerable to the adverse impact of climate change. 

Context

UNEP-DHI Partnership presents a series of 6 webinars that will give an introduction to the basic challenges and issues related to water quality.

Join our CTCN Consortium Partner, the Tropical Agricultural Research and Higher Education Centre (CATIE) for this introductory webinar on technologies for adapting to climate change in the water sector.

Technology Description: Researchers in Dr. Alfred Spormann’s lab have developed a PCR-based method for analyzing the community composition of bacteria belonging to the genus Dehalococcoides. In much of the 20th century chlorinated organic compounds such as perchoroethylene (PCE) tricholoroethene (TCE) or vinyl chloride (VC) were used for a variety of purposes. These compounds are now common groundwater soil and sediment contaminants and clean-up costs are estimated to be billions of dollars. One method of cleaning-up these contaminants is bioremediation via reductive dechlorination.

This invention comprises a novel design for a microbial cell that has an electrode colonized by a unique strain of Geobacter lovleyi. This bacterium forms a biofilm directly on the electrode surface. The biofilm then utilizes electrons transferred directly from the electrode surface for reductive dechlorination of TCE and PCE to cis-DCE. TCE/PCE groundwater contamination is a serious issue for a majority of the \"Superfund\"" sites identified by the EPA as sites that require decontamination.

Unique particles derived from acrylonitrile or other materials which are capable of selectively absorbing uranyl from groundwater surface water and wastewater.Applications:This technology can be used to improve the quality of a water supply by safely effectively and inexpensively removing uranyl ions from the water. The presence of uranium in groundwater is a growing problem in the United States and one without effective treatment to date. These particles can also be used in portable field systems for analysis of uranyl content on site.

Chemical contaminants such as nitrogenous wastes found in aquacultures or groundwater may contaminate nearby areas and drinking water supplies. Groundwater pollution may be caused by activities such as industrial waste disposal accidental spills fuel tank leakage or application of fertilizers herbicides or pesticides to crops. Natural causes such as arsenic also may result in groundwater contamination. Organisms are a major cause of water and aqueous environment contamination and are one of the world’s largest health concerns.

Écotech Québec in Canada is a centre of excellence for cleantech in North America and is continuously compiling overviews of clean technology expertise available in the Province of Québec. The Clean Technologies overview provided by Écotech Québec offers information sheets with contact information on several hundred service providers across a variety of sectors, including Air, Green Chemistry, Water, Eco-Mobility, Energy Efficiency, Renewable Energy, Waste, Soil and Groundwater and Enabling Technologies.

Method and device for extracting groundwater using high vacuum

This technology has been identified by KOTEC(Korea Technology Finance Corporation) for WIPO GREEN's project in waste water treatment sector. Any request for contacting the technology provider will be facilitated by KOTEC. Integrated electrochemical system is composed of three electrochemical unit processes: electrochemical separator electrodialysis and electrolysis. This technology is aimed to remove various pollutants in water and wastewater including ionic pollutants such as nitrate and ammonium biological pollutants such as E. coli and heavy metals such as arsenic and lead.
