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, ...
In the absence of safety measures (as in old landfills) and depending on soil conditions, hazardous substances are flushed by rain into the groundwater. Depending on the type of usage, a number of different hazardous substances can be found, including, among others: Heavy-metal compounds: Copper, lead, chromium, nickel, zinc and arsenic (a metalloid) Organic materials: Phenols, ...
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 ...
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. ...
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. ...
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 ...
