Preparation of slow-releasing oxygen materials and study on their properties
Slow-releasing oxygen materials were prepared to overcome some limitations regarding the low dissolved oxygen (DO) concentration and the low efficiency of in-situ purification in groundwater. Tests on slow-releasing oxygen materials that could be used to change the reductive environment in groundwater by slowly releasing oxygen were carried out. Oxygen-releasing laboratory experiments were ...

Deriving site‐specific soil clean‐up values for metals and metalloids: Rationale for including protection of soil microbial processes
Although it is widely recognized that microorganisms are essential for sustaining soil fertility, structure, nutrient cycling, groundwater purification and other soil functions, soil microbial toxicity data were excluded from the derivation of Ecological Soil Screening Levels (Eco‐SSL) in the United States. Among the reasons for such exclusion were claims that microbial toxicity tests were too ...

The Opportunity for Municipal-Agricultural Water Partnerships in California
Policy report puts an emphasis on nontraditional sources like desalinated and recycled water Despite their dissimilarities, the people and economies of California’s San Joaquin Valley and the major cities of Southern California are inextricably linked by their reliance on the same water resources, and they share an interest in protecting them to secure a future supply of dependable, ...

Temperature effects on bank filtration: redox conditions and physical-chemical parameters of pore water at Lake Tegel, Berlin, Germany
In the city of Berlin, artificial groundwater recharge techniques, such as bank filtration and infiltration ponds, are an important source for drinking water production. Climate change with increasing surface water temperatures can influence the water purification processes during bank filtration mainly due the intensification of metabolic processes leading to a decrease of oxygen and an increase ...

Evaluating the performance of water purification in a vegetated groundwater recharge basin maintained by short-term pulsed infiltration events
Infiltration of surface water constitutes an important pillar in artificial groundwater recharge. However, insufficient transformation of organic carbon and nutrients, as well as clogging of sediments often cause major problems. The attenuation efficiency of dissolved organic carbon (DOC), nutrients and pathogens versus the risk of bioclogging for intermittent recharge were studied in an ...

Polluted sites: Groundwater decontamination requires robust level sensors
Whether it be old landfills, coal tips, former military sites or refineries, what remains behind is contaminated ground, which is a danger to both humans and the environment. In the rehabilitation of these sites, level sensors are required which are resistant to the often aggressive hazardous substances encountered. Contaminated sites are not only characterized by adverse health or environmental ...
