Groundwater contamination doesn’t move in neat, predictable intervals. Yet for decades, environmental monitoring programs have relied on quarterly or annual sampling as the standard approach to understanding subsurface conditions. While this method has been widely accepted, it introduces a critical challenge: it captures only snapshots in time,not the full story. As regulatory ...

The Interstate Technology and Regulatory Council published its Vapor Intrusion Toolkit in January 2026. The Toolkit consolidates three earlier ITRC documents into one resource: the 2007 VI-1 guidance, the 2014 PVI-1 petroleum guidance, and the 2021 VIM-1 mitigation ...

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 ...

Why Do Static Monitoring Networks Waste Money? Most groundwater monitoring programs operate under networks designed years or decades ago. These networks persist unchanged despite accumulating data that could inform more efficient sampling strategies. The result represents a hidden cost that compounds annually, with typical contaminated sites paying 20 to 40 percent more than necessary for ...

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 ...

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 ...

The Global Contamination Challenge Over 2 million contaminated sites exist globally, and we continue polluting more sites than we clean up. This disparity between the problems we face and our ability to solve them through innovation creates what I call an ingenuity gap. The gap persists not because solutions do not exist, but because industry practices lag behind scientific advances by decades. ...

When contractors think of truck-mounted soil sampling rigs, they often picture large models mounted on heavy-duty trucks that have difficulty getting into hard-to-access areas. However, Lone Star Drills offers the option to mount some rigs on light- to medium-duty trucks that offer quick setup and more versatility than large truck-mounted drills. Below, we run through benefits you’ll ...
Cubic Instruments Solution: Advanced Gasboard-9050 CEMS for Gas Turbine Combustion Optimization To meet the demanding requirements for industrial applications, Cubic Instruments, a leading manufacturer of advanced gas sensors and gas analyzers, has developed Continuous Emissions Monitoring System (CEMS) Gasboard-9050, which is well-suited for supporting real-time gas turbine ...
How our in-house pilot studies replicate field conditions to generate meaningful methane data. In a previous blog we discussed some of the pros and cons of BMP studies on anaerobic digesters. While they’re excellent for showing how much methane can be produced from a food substrate, they have less utility as a representative site study and will only work well in some cases. The best-case ...
However, concentrations of airborne synthetic particle in indoor and outdoor environments are not well understood due to the complexities of sampling, sample processing and identification. ...
In modern laboratories, efficiency, accuracy, and traceability are non-negotiable. As labs handle increasingly complex workflows and growing sample volumes, manual data entry and paper-based tracking systems are no longer sustainable. One powerful way to improve operational performance is by integrating barcoding technology with a Laboratory Information Management System (LIMS). This integration ...
The ActiveCount Remote Impactor Kit is designed to provide a flexible, modular solution for viable sampling in critical environments. Whether you rely on a house vacuum system, use an ActiveCount viable sampler, or require a remote sampling setup, this kit is engineered to adapt seamlessly to your existing processes and scale as your needs evolve. ...
They can be very useful in transporting heavy loads such as pallets or containers as well as lifting, retrieving and placing materials and goods between locations. ...
Summary This study aims to evaluate the on-site impacts of Qwik-Zyme D, a product by Aquafix, Inc., in an aerobic digester at the Columbus, WI Wastewater Treatment Facility. Qwik-Zyme D is formulated to enhance the degradation of hard-to-degrade organic compounds and has shown promising results in boosting solids reduction in various field applications. Over a 12-week period (April 28 2024 ...
Cost and Throughput: Financial constraints play a significant role in method selection. 16S rRNA sequencing is generally more economical and allows for high-throughput analyses, while metagenome sequencing is more expensive due to the complexity of data generated. Sample Complexity: For samples with a well-defined set of known microorganisms, 16S ...
The current sampling methods for electric meters mainly include the following types, each with its own characteristics and applicable scenarios: 1.Transformer-Sampled Electric Meter · Definition and Principle A transformer-sampled electric meter uses voltage transformers and current transformers to collect the user’s voltage and current signals, ...
The Harrison Wastewater Treatment Plant is a 2.3 MGD average daily design flow wastewater plant servicing the City of Harrison in Southwest Ohio. During the pilot testing, the plant was receiving an average daily flow of approximately 1.1 MGD. Due to local industries and residential waste, the influent wastewater to the Harrison plant occasionally experiences a high fat, oil, and grease (FOG) ...
