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 ...

The Well Redundancy Problem Every groundwater monitoring network includes wells that cost money but provide no commensurate value. This statement reflects reality at contaminated sites worldwide, not a criticism of the hydrogeologists who designed these networks. Contamination plumes evolve over time, and our understanding of subsurface conditions improves as data accumulates. A well that ...

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. ...
In the quest for cleaner water and more accurate environmental monitoring, advancements in water sampling methods are essential. Among the latest breakthroughs, PTFE (polytetrafluoroethylene) tubing is proving to be a game-changer, setting new standards for efficiency, reliability, and precision in water ...
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 ...
Enzyme activities are often monitored because they give researchers a deeper understanding of industrial and biomedical reactions and spectrometry is one of the most common methods used to monitor enzyme activity. It is an effective and accurate method that allows real-time analysis of reactions and their byproducts. This blog will outline how dissolved species analysis helps to study enzyme ...
Volcanic gases are released by active volcanoes and significantly impact our atmosphere and environment due to the air pollutants, gases, and particles they emit. The four most common types of volcanic gases are carbon dioxide, hydrogen sulfide, sulfur dioxide, and water vapour. These can be monitored via ground-based instruments so that analysts can understand more about the gases and their ...
Climate change studies Stable Isotope Analysis Monitoring nitrogen pollution in coastal waters Measuring isotopically labelled species in wastewater Specialised inlet technology for denitrification studies Enzyme Activity Studies Real-time analysis of dissolved gases in enzymatic solutions Direct measurements of reactants and products in real-time ...
The units are used for remote monitoring of groundwater resources around Thailand, compared to previously taking samples from around the country and sending them to the main cities for analysis. The Groundwater Analysis Division at the Department of Groundwater Resources for Thailand has quite a mandate! ...
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 ...
Client: Lake Simcoe Region Conservation Authority: Ms. Katie Howson, Subwatershed Protection Planner, 120 Bayview Pkwy, Box 282, Newmarket, ON L3Y 4X1 (905.895.1281) Key Personnel: E.J. Wexler, D. Kassenaar, A. Kodippili The Lake Simcoe Protection Plan contains policies requiring that each subwatershed in the Lake Simcoe Watershed undergo a Water Budget and Stress Assessment to ...
Wexler Working for the Toronto and Region Conservation Authority (TRCA), Earthfx provided key surface water and groundwater analysis components of the Humber River Watershed Plan. The watershed is the home to over 800,000 residents, including the western portion of the City of ...
Project Description: Land development in the Greater Toronto Area (GTA) is encroaching on the high recharge areas of the Oak Ridges Moraine (ORM). The ORM provides drinking water for over 2 million residents and headwater streamflow for all the major rivers in the GTA. As part of provincial efforts to protect the moraine, Earthfx was hired to develop a database, regional scale groundwater flow ...
TerraStryke Products LLC (TerraStryke) develop-distribute biostimulation additives proven to cost-effectively enhance chlorinated volatile organic compound (cVOC) biotransformation safely and completely. Our patented biostimulation additive ERDENHANCED leverages existing biogeochemical conditions to facilitate chlorinated alkane/alkene destruction. ERDENHANCED is proven to expedite residual mass ...
It is an essential technique for groundwater chemistry. Consequently, it is used in the analysis of the chemical composition of rock materials. Human dependence on groundwater for various uses such as drinking water necessitates the need for extensive analysis and understanding of groundwater chemistry. Since ...
LIAG purchased the state-of-the-art Javelin Wireline including both 2.38 (60 mm) inch and 3.5 inch (90 mm) NMR logging tools in order to have a high degree of flexibility for groundwater analysis projects. The LIAG staff are very happy to have their new Javelin tools which will allow them to perform NMR measurements in a wide variety of borehole and well sizes, ...
