Background Storage and pumping of jet-fuel have caused a severe contamination of soil and groundwater at a military facility in Denmark. The contamination was detected in 2001. ...
Access to clean water is getting tougher for many coastal communities. Despite having seawater surrounding them, the salinity level is too high for consumption, agricultural use, and use in industries. That’s where desalination systems come in. By converting seawater into freshwater, potable water, these systems become a long-term source for coastal communities’ ever-growing water ...
In remote Chilean projects, contractors often bring additional mobile water storage or use local collection systems, such as rainwater catchment or groundwater extraction, to supplement the mixer’s tank. 3. Temperature and Altitude Effects on Mixing At higher altitudes, the reduced air pressure and colder temperatures can affect the curing process and ...
Wedge Wire Filter Nozzles Designed for groundwater extraction, abstraction, and municipal water supply filter wells. 5. ...
It is especially important in the extraction, transportation and processing of crude oil and natural gas. •Application: oil and gas extraction, natural gas transportation, oil-water separation process, gas stations, etc. 6. ...
Environmental Monitoring Monitoring river flows, groundwater extraction, or wastewater discharge to meet regulatory compliance. ...
The bedrock has relatively low permeability and therefore acts as a barrier to vertical groundwater flow. The entirety of Sydney Airport is located within a ‘Groundwater Embargo Area’. This zone has been set aside as a buffer zone around the ‘Groundwater Extraction Exclusion Zone’ from ...
If you work in mining or with customers in the mining industry, you will be used to finding air operated double diaphragm pumps (AODD) in many of their processes. If this is the case for you, we invite you to read on…In this article you will find:The reasons for choosing pneumatic double-diaphragm pumps in mining.Advantages offered by Samoa Industrial’s pneumatic double diaphragm pumps in mining ...
Groundwater contamination is a significant environmental challenge faced by many regions worldwide. Pollution resulting from hydrocarbons and other contaminants can have disastrous consequences on both the environment and human health. Therefore, the need for effective groundwater remediation methods cannot be overemphasized. In this article, we will discuss some of the groundwater remediation ...
Saltwater intrusion is exacerbated by sea-level rise and groundwater extraction. Rising sea levels are pushing seawater further inland, and pumping fresh water from aquifers leaves a void that is filled by the salt water. A 2012 study found that coastal aquifers are more vulnerable to groundwater extraction than to rising sea ...
Introduction: India is the largest consumer of groundwater in the whole world. It uses around 230 cubic kilometers of groundwater per year, which is over a quarter of the global total. More than 60 percentage of groundwater in India is used for irrigation, whereas almost 85% of groundwater is used for drinking purposes. Even though groundwater is a renewable water resource, the world’s ...
Out of the total world population which happens to be around 7.9 billion, India accounts for 17% of it. The country with such a dense population holds only 4% of the world’s freshwater resources. With 20 basins throughout the country, their average annual water availability is about 1,999.20 billion cubic meters (BCM) as natural runoff. This average figure is dependent on the regions and ...
Site Summary BioLogix CL bioaugmentation was implemented in combination with dual phase extraction at an industrial site near Houston, Texas to remove trichloroethylene (TCE) from ground water. The overlying contaminated soil was excavated, but perched ground water and a deeper aquifer had TCE concentrations greater than 10,000 |jg/L A dual-phase vacuum extraction system was installed to control ...
Site Summary: BioLogix CL bioremediation was implemented at a dry cleaners site in Houston, Texas to reduce residual PCE and other chlorinated solvent concentrations in groundwater following dual phase vacuum extraction. After application of BioLogix CL® bioremediation the chlorinated solvent concentrations were reduced by 98% to 99% in less than 90 days. ...
Can managed aquifer recharge slow the land subsidence that threatens the city’s infrastructure? Before the Aztec city of Tenochtitlán fell to the Spaniards, it was an island on flood-prone Lake Texcoco. Spain founded Mexico City on its ruins and over the centuries drained most of the lake to provide more land for growth. In the late 19th century, officials began to notice that ...
Findings may be used to guide water management decisions, such as adoption of water reuse When water is pumped from aquifers, it can be replaced either naturally or artificially through groundwater recharge. Natural recharge comes from the slow infiltration or percolation of precipitation or surface water, and artificial recharge increases the rate through human-controlled ...
Site Information A confidential dry cleaners site was contaminated by residual PCE and other chlorinated solvent concentrations in groundwater following dual phase vacuum extraction. The soil and sediments beneath the site have a moderate hydraulic conductivity estimated at 10-4 cm/sec. ...
In Situ Bioremediation Eliminated Pump and Treat and Ion-Exhange Treatment Cost Site closure reached in less than half the time and at less than half the cost CL-Out bioremediation was implemented at a confidential manufacturing site to remediate nitrate and perchlorate concentrations in soil and ground water. A pump and treatment system was installed and operated for years in immediate response ...
Abstract: A chlorinated solvent plume (perchloroethylene or PCE) was discovered in the shallow ground water as a result of historical operating practices surrounding a Houston area dry cleaning facility. Permeable shallow soil at the site allowed rapid vertical migration at the source and lateral migration in the shallow ground water. This migration resulted in an off-site migration of the plume ...
” In the context of hydrogeology, it refers to a natural underground formation of permeable rock or sediment that stores and conducts the groundwater we access through wells and springs. A healthy aquifer not only supplies water, but also helps purify groundwater. ...
