GoForth, NC Case Study
ABSTRACT Trap & Treat® BOS 200® was used to remediate petroleum hydrocarbon impacted groundwater within fractured bedrock and overburden soil at a former retail gasoline site in North Carolina. After a thorough remedial design characterization was completed, BOS 200® was surgically injected over two field events to successfully achieve the site cleanup goals. CHALLENGES The site was formerly a general store with two 1,000 gallon USTs; the primary constituents of concern were Benzene, Toluene,...
Fractured Bedrock Remediation - Case Study
ABSTRACT BOS 200® successfully remediates petroleum groundwater impacts in fractured bedrock at a former truck stop. Based on the post-injection groundwater results from the pilot test and full-scale injection, a No Further Action letter was issued in February 2015. CHALLENGES Over a period of 20 years, site investigation activities revealed a 320 foot (ft) long dissolved hydrocarbon plume within the fractured bedrock. Light non-aqueous phase liquid (LNAPL) was identified in one monitoring well and benzene...
Large Precipitation Events are Critical in Replenishing Groundwater Resources
Large precipitation events that occur about every 10 years are a critical source of recharge for replenishing groundwater resources, according to a new study by the U.S. Geological Survey and the Bureau of Reclamation. Groundwater is a vital source of water in the western United States, and will be increasingly important with continued population growth and climate variability. Understanding the role of these large recharge events in replenishing aquifers and sustaining water supplies is crucial for long-term...
Future hydrogeologist wants to mitigate groundwater contamination
NGWA continues its monthly spotlight look at the 2016 Len Assante Scholarship winners from the National Ground Water Research and Educational Foundation. This month we get to know winner Jay Kim. Kim, of Kalamazoo, Michigan, received the first Richard Haderer Award of $3,000. Kim is working on his master’s degree in glacial geology and hydrogeology at Western Michigan University. The Haderer Scholarship was established in 2016 by Paul Haderer in honor of his late brother, Richard. Working as a hydrogeologist...
Removal of perfluorooctanoic acid (PFOA) in groundwater by nanofiltration membrane
Perfluorooctanoic acid (PFOA) is very persistent in the environment and resistant to typical degradation processes. PFOA has been widely used in surface-active agents and as an emulsifier in several products and can contaminate groundwater. Groundwater is considered as an important source of water; hence removal of PFOA contamination in groundwater is needed. This study aimed to examine the removal of PFOA in spiked deionized water and spiked groundwater samples by nanofiltration (NF) membrane. PFOA removal...
