The traditional pump-and-treat solution has been applied to the remediation of PFAS-impacted groundwater, but it is expensive and can take decades to achieve any signifi cant levels of removal. ...
Continuous Water Quality Data Brings New Perspective to Pumping Tests Overview Looking for a more efficient and reliable method of collecting, transmitting and analyzing data, A&H Well Services designed a custom system using several technologies to expand their capabilities and give customers real-time access to step test and pumping test ...
Overview A Southern California groundwater management agency is capitalizing on the latest remote water monitoring technology to simplify and expand access to continuous groundwater data used to ensure a sustainable water future for its service area. Challenge The Water Replenishment District (WRD) is responsible for monitoring and testing ...
Past characterization activity documented adverse impacts to subsurface soils and groundwater. Previous remedial efforts proved ineffective and costly. Owner desired a low-cost, low-impact remedial solution that meets compliance and redevelopment objectives. ...
Monitoring wells are utilized for groundwater testing and observation. Another area to be incorporated in the ongoing HRI subsurface drip irrigation reclamation project is the BYUH 1.8 hectare rugby field and adjacent baseball field. ...
Overview Wesleyan hydrology students used the Level TROLL 700 to monitor groundwater levels and perform slug tests to understand how climate change may impact aquifer recharge in the northeastern U.S. Challenge Students wanted to explore how climate change might impact groundwater levels in the Northeast, where precipitation is becoming less ...
This is not a routine test. Obtained values during testing are applicable only to the sewer tested and time of testing. ...
Exposure may be through ingestion, dermal contact, inhalation, or groundwater. For soil assessment levels, two categories exist; Health Investigation Levels (HILs) and Ecological Investigation Levels (EILs). ...
As part of any Brownfields project, preliminary soil and groundwater tests characterize the nature and amount of contaminants present. ...
Abstract: The McArthur River mine in northern Saskatchewan is the largest single producer of uranium in the world. Most of the ore is extracted by raisebore mining methods at depths of 530 to 600 m below ground surface where pore pressures in the fractured host sandstone and gneiss are on the order of 5 MPa. Currently, ground freezing is used to isolate the ore from ground-water sources. ...
CHALLENGE: An excavation exceeding 20 feet deep which is at, or in some areas below, the water table elevation was necessary for the new construction. Groundwater testing showed contamination with volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs) and lead. ...
As part of any Brownfields project, preliminary soil and groundwater tests are needed to characterize the nature and amount of contaminants present. ...
Clean-up may not just be on your property but any other property including surface and groundwater that may have originated on your property. A Phase I ESA provides the appropriate level of “due diligence” in the transaction. ...
When it comes to groundwater monitoring, testing the water often requires the creation of a borehole at the test site to reach the water below. ...
This overburden contains all sorts of materials like clay, sand, gravel and limestone. This is also where the groundwater resides. That rising mine water particularly affects the groundwater level, not so much the groundwater ...
Underground storage tanks (USTs) removed; however, past use adversely impacted on/off-site saturated soils/groundwater. Limited test zone amended over 6-month period using additive filled passive release sock (PRS) deployment units; 2-pounds additive each, 2 units deployed per event. ...
The system also needed to be water-tight when filled with 1.6 million gallons of stormwater while passing a mandatory 24-hour leak-test. To complete the test, groundwater was pumped into the tank, then measurements were taken two days later to document any water loss. ...
Hazardous Materials at Construction Sites Hazardous materials such as silica, lead, metals, pesticides, chemicals, and gases are often found on construction sites. Where ground or groundwater testing identified hazardous materials that may be carried off-site during excavation or just routine construction activities where dust or fumes may be generated, air ...
Construction may occur on old factory sites, landfills, former railways, illegal dumps where the ground, soil, and groundwater may be contaminated from years-even decades- in the past. Most construction projects specify that a Site Specific Health and Safety Plan (HASP) be developed that addresses all the safety and HEALTH hazards and what to do to protect workers and neighbors, ...
What is groundwater? Groundwater is water that is stored below the earth’s surface. ...
