Confidential Site Near Los Angeles, California - Case Study
This site recently completed its 33rd quarter of groundwater monitoring with the Snap Sampler. To compare variability of the Snap Sampler with traditional volume purge methods, contaminant concentration changes over 9 monitoring periods were compared. Quarter-to-quarter changes in contaminant concentrations were tabulated and quarter-to-quarter relative percent change was compared. There were 81 ...

Recycling Facilities Can Be Hazardous to Workers’ Health
A great majority of municipalities and private companies in the United States have recycling facilities where metal, glass, chemicals, paper, wood, batteries, electronics, and clothing are deposited from collection trucks, and sorted by workers, usually along conveyor belts. The workers in these facilities are potentially exposed to a wide variety of health hazards. Vehicle Exhaust One health ...

Low-flow groundwater sampling on a nuclear site - Case Study
Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...

Application of a novel sampling bailer device for the analysis of dissolved methane concentrations in municipal wastewater during and following anaerobic treatment
Modern wastewater utilities need to be able to measure and quantify the amount of methane from their treatment facilities in order to understand the potential energy that can be produced and the amount of methane being lost. This paper describes the application of a novel sampling bailer designed for the collection of wastewater samples that minimises methane losses. Samples collected during ...

Headspace gas chromatography with flame ionization detection (HS-GC-FID) for the determination of dissolved methane in wastewater
There is currently a need for a simple, accurate and reproducible method that quantifies the amount of dissolved methane in wastewater in order to realize the potential methane that can be recovered and account for any emissions. This paper presents such a method, using gas chromatography with flame ionization detection fitted with a GS-Gas PRO column coupled with a headspace auto sampler. A ...

Leaks and spills - LNAP and DNAPL detection and clean up
Any tank can leak. Most leaks can be cleaned up and responsible operators need equipment that does what’s needed. With an ATEX Zone 0 certified interface meter site operators can successfully achieve LNAP and DNAPL detection when monitoring petrochemical sites, tank farms, petrol station forecourts, landfills or remediation sites. If site technicians detect leaked product with an interface ...

Effective Groundwater Monitoring Using Dedicated Pumping Tubes
This article describes a groundwater monitoring procedure that does not require decontamination of pumping equipment, eliminates the chance of cross contamination between wells, and uses a surface pump. Two surface pumps are described, one for water level depths less than 25 feet and one for water level depths greater than 25 feet. Install Dedicated Pumping Tubes A dedicated pumping tube ...

Mather AFB demonstration of hydrasleeve no-purge samplers
MWHS Americas, Inc. (MWH) was contracted by Dolver Company, Inc. to perform a Point Source Bailer Demonstration at Mather Air Force Base (Mather). This demonstration was initiated to evaluate no-purge technology and indicate the feasibility of using the HydraSleeve no-purge samplers as an alternative groundwater sampling method. On June 18, 2002, eight HydraSleeve point source bailers were ...

A new no-purge, non-displacement groundwater sampler
What Is It? The HydraSleeve sampler is designed to collect representative water samples from monitoring wells without purging. The disposable sampler collects a discreet sample from only the 'fresh formation' water in the screened interval of the well. It is fast, inexpensive, simple to use, generates no purge water and collects a sample suitable for all analytical parameters. Why It Works The ...

Performance Testing of Conventional and Innovative Downhole Samplers and Pumps for VOC`s in a Laboratory Monitoring Well
Untitled Document ABSTRACT Concentrations of groundwater contaminants in samples that differ from concentrations in the aquifer can lead to incorrect conclusions about the extent and severity of contamination and the effectiveness of remedial measures. Sample collection and storage techniques affect measured concentrations in samples, particularly of organic compounds that ...

Evaluation of Sampling and Field-Filtration Methods for the Analysis of Trace Metals in Ground Water
Selected ground water sampling and field-filtration methods were evaluated to determine their effects on field parameters and trace metal concentrations in samples collected under several types of field conditions. The study focused on conditions where traditional approaches may produce turbid samples, which often leads to filtration of suspended particles from the sample before laboratory ...

Stable lead isotopes reveal a natural source of high lead concentrations to gasoline-contaminated groundwater
Concentrations of total lead as high as 1,600 g/L were detected in gasoline-contaminated and uncontaminated groundwater at three gasoline-release sites in South Carolina. Total lead concentrations were highest in turbid groundwater samples from gasoline-contaminated and uncontaminated wells, whereas lower turbidity groundwater samples (collected using low-flow methods) had lower total lead ...

The Alternative to Pump and Treat
Sometimes, an important technological advance begins with a small step – back! Such is the case with remediation of hydrocarbons from groundwater utilizing existing recovery and monitoring wells. For the past few years, state government has based decisions on the amount of clean up that they require by the risk posed to the environment. Risk Based Corrective Action, commonly called 'Rebecca' ...

Decontaminating Groundwater Sampling Devices
These studies are the second part of a two year project that examines decontaminating groundwater sampling devices. In the first year, the efficiency of various decontamination protocols was tested using small test pieces of materials that are commonly used in groundwater sampling devices. Those tests showed that a hot detergent wash and rinse followed by hot air drying (105°C) was the most ...

Groundwater Monitoring with the Waterra Inertial Pump
Untitled Document Abstract The Waterra Inertial Pump has been available for use in narrow diameter monitoring wells for several years. This device offers many advantages over other types of sampling equipment. Since this pump operates via a principle not used by any other type of device and is commonly constructed of materials not widely used in field sampling, some ...
