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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
