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 ...

Low Flow Groundwater Sampling Using RotaPump Inertial Lift Pump

This article tells you how to perform low flow groundwater sampling using a portable, surface-mounted pump with no decontamination required before each use and no chance of cross contamination between wells. An inertial lift pump moves a dedicated (stored in the well) pumping tube rapidly up and down. A one-way valve on the bottom admits water on the down stroke and ...

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 ...

Case study - Low-flow groundwater sampling on a nuclear site

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 ...

Optimal groundwater contamination monitoring using pumping wells

This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...

Technical Bulletin: Multilevel Sampling

The topic of this CL:AIRE Technical Bulletin is multilevel sampling systems for characterising contaminated groundwater. Contaminated groundwater can present considerable problems for landowners: it can occur at significant depth, sources of the contamination are not often obvious, it can migrate from one property to another, and groundwater flow directions can be altered due to seasonal ...

Analysis of TNT and RDX in groundwater

MATRIX: Water ANALYTE: TNT and RDX LIMIT OF DETECTION: TNT 1 ppb (mg/L), RDX: 5 ppb (mg/L) BACKGROUND: This application describes a field screening method for determining TNT and RDX concentrations in water. The method uses solid phase extraction to remove and preconcentrate the analytes from water. In the method, a 2 ...

Improving Groundwater with Chemical Treatments

Groundwater contributes to the health and well-being of a natural environment in the area and those systems connected to it. There are times that contaminants create an imbalance in groundwater, and a groundwater treatment system needs to be applied. Here are some chemical treatments that work to help ...

Norfolk CC tackle groundwater contamination with low-flow

Quick and easy access in deep wells Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. Elizabeth Guilford of Norfolk County Council hired the low flow kit from Geotech and used it on a Norfolk CC landfill where leachate contamination of groundwater was suspected. Samples taken at 2m intervals ...

Groundwater Contamination Plume Remediation - Case Study

19 CMT Multilevel Systems Successfully Installed in Challenging A facility in Pontypool, Wales, UK was once the location of a plastic forming plant. Over time, chemicals produced through the plastic forming processes were lost into the groundwater beneath the facility, creating a large contaminant plume. Years later it was determined that the plume is ...

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 ...

In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...
