INTRODUCTION Environmental Material Science ("LiORA") provides a new generation of Internet of Things (loT) enabled non-dispersive infrared (NDIR) water sensors that provide high-resolution quantification of groundwater (GW) petroleum hydrocarbon (PHC) concentrations. The current generation water sensor transmits data at 30-minute intervals using a 4-channel pyroelectric NDIR detector, along ...

Understanding What Monitoring Frequency Reveals Why Frequency Determines Knowledge I spend considerable time thinking about how we measure things underground. The physical act of lowering a bailer into a well or watching a pump purge three volumes of stagnant water forms only part of the story. The deeper question concerns what those groundwater measurements tell us and what the measurements ...

Fast Dissolved Gas Analysis for Groundwater Age, Recharge and Flow Paths Mass spectrometry for groundwater studies provides real-time detection of transient events and supports reliable, efficient groundwater quality monitoring to help ensure the safety and sustainability of water supplies. ...
REMEDIATION APPROACH The material was injected in form of an aqueous suspension employing the pressure injection into permanent wells in August 2018. The groundwater and soil were periodically sampled before and after the remediation event. ...
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 ...
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 ...
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 ...
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 ...
