Ten months later, remediation was boosted by circulation and solar warming of groundwater and whey dopping. The groundwater and soil were periodically sampled before and one year after the pilot test. ...
Seasonal changes can affect runoff, groundwater, and surface water supplies, making environmental sampling and water filtration more important than ever. ...
As winter melts into spring, environmental field teams gear up for one of the busiest times of the year: the spring sampling season. With snowmelt runoff, rising groundwater levels, and increased mobility in field conditions, spring is a critical window for collecting representative groundwater samples—especially in regions ...
Resilience: Weathering Challenges Like Fluoropolymers One of the most celebrated properties of fluoropolymers, such as PTFE, FEP, and PFA, is their resilience. These materials withstand extreme temperatures, corrosive chemicals, and intense wear-and-tear, making them indispensable in industries ranging from aerospace to environmental monitoring. As you plan your resolutions, think about the ...
It triggers and amplifies the remediation capabilities of nature for a fast, cost-efficient and environmentally friendly cleaning effect. A groundwater pumping and nutrient addition system was also applied to enable the fastest growth of oil degrading microbes. The application generated natural and massive mineralization of the diesel contaminant in both ...
Vane pumps, a type of positive displacement pump, are essential in hydraulic systems due to their proficiency in handling low-viscosity fluids at relatively high pressures. Characterized by their unique design, these pumps consist of a series of vanes mounted to a rotor that rotates inside a cavity. As the rotor spins, the vanes extend and retract due to centrifugal force and the interaction ...
Here’s what ESdat offers:Define Sampling Locations: Easily designate sampling locations for groundwater, surface water, soil, or landfill gas monitoring.Specify Laboratory Samples and Analyses: Specify the required analyses and containers for laboratory samples, ensuring accuracy and consistency.Recurring ...
The subject site is a former dry cleaning facility in Northern Europe, where a large tetrachloroethylene (PCE) plume was impacting groundwater on and off-site. In 2017, CAT 100 and BOS 100® were applied as part of a large-scale remediation program. Currently, a 95% average reduction in PCE plume concentrations has been observed in the monitoring wells located in the areas targeted by the ...
Marshall Iron & Metal in the City of Marshall, Michigan, operated as a railroad maintenance yard from 1899 to 1931 and a foundry from 1938 to 1960. Most recently, it served as an auto salvage/metal scrapyard from 1961 to 1996. Excavation and disposal of soil and debris were completed in the fall of 2015. During these activities, light non-aqueous phase liquid (LNAPL) was observed in an ...
The subject property formerly operated as the Retail and Commercial Farm facility. The facility formerly stored and sold feed, farm equipment, and various farming chemicals (fertilizers, herbicides, and pesticides, etc.). In 2015, prior to the potential sale of the property, a Phase I Environmental Site Assessment (ESA) and subsequent Phase II ESA were undertaken. The Phase II ESA identified ...
Several methods are employed to detect and quantify these pollutants: Sampling and Sample Preparation: To analyse emerging contaminants in water, researchers collect water samples from various sources, including rivers, lakes, and groundwater. These samples are then subjected to a series of preparation steps to ...
The textbook approach to new or legacy spills is to ensure that you have a vertical and horizontal delineation of the pollutants. This understanding of how deep and wide your pollutant has travelled is essential before you can begin any remediation, restoration, or reclamation process. The rationale for this approach is that we should not begin a remediation process until we have enough ...

30 years of data show salinity of groundwater increasing even far from coasts After 30 years of monitoring wells, the latest U.S. ...
The core barrel is then retrieved, producing a relatively undisturbed sample with near 100% core recovery. These steps are repeated to depth, producing a continuous core sample even through unconsolidated formations. ...
It includes different steps: Answering the Initial Ecological Assessment Screening Questions found in that methodology document If "yes" is the response to any of the four questions, then the sampling findings should be compared to the HSCA Screening Levels for ecological sediment, surface water, and surface soil, as appropriate. If any sampling results are ...
Hydrocarbons are organic compounds composed of hydrogen and carbon atoms and are the building blocks of many fossil fuels. Petroleum products, such as gasoline, diesel, and oil, are major sources of hydrocarbons. Spills or leaks of these products can result in soil contamination, and if left unaddressed, can have significant environmental and health impacts. In this article, we will discuss the ...
Date Conducted: March 2012 to December 2013 (project in progress) Client: Arizona DEQ Oversite Agency: Arizona DEQ Project Description: Vapor intrusion assessment of over 100 residential units located over a PCE groundwater plume. Hartman providing work scope, overseeing soil gas sampling program to define groundwater contamination, conducting ...
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. ...
Climate change studies have been increasingly common and important in recent years. The impact of human activities on the environment, global warming, and sea level rises have been well documented and debated, and whilst we have gained a deeper understanding of these issues in recent years, there is still so much more to learn. In this article, we discuss how the pQA from Hiden Analytical can be ...
Site Description Chlorinated solvents were found in soil and around water beneath a drum storage area at a manufacturing facility in central Indiana. The contamination was mainly found in the uppermost occurrence of ground water in an intratill silty sand formation. Within this zone the contamination had spread to cover an area of approximately 3,500 square ...
