Contaminant Site Investigation Applications

Characterization of contaminated groundwater requires detailed monitoring to eliminate data gaps, improve predictive numerical models, and track remedial efforts. The Westbay System is a reliable, cost-effective technology for obtaining detailed information, enabling groundwater professionals to carry out comprehensive and defensible contaminant site investigations and long-term monitoring.

Groundwater Monitoring for Construction Sites

All construction affects groundwater and a water management plan will be required. From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater. Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise and flood in a shorter time, but also to dry up sooner. These conditions cause great difficulties for subsistence farmers in developing countries. Urbanisation also causes faster run off because of the non permeable surfaces such as roads, roofs and car parks. This also creates drainage problems that can lead to contamination and erosion of natural water courses.

Measurement of naphthalene in ambient air to monitor workplace exposure limits & at remediation & Superfund sites

The Series 8900 Naphthalene Analyzer provides direct measurement of Naphthalene in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits and at remediation and Superfund sites. The Series 8900 Naphthalene Analyzer employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Naphthalene and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Naphthalene is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Airport Environmental Monitoring

Water pollution from airport run-off is increasingly coming under public and government scrutiny. As environmental regulations tighten, the ability to monitor for aviation fuel contamination from runway run-off has become essential.

Monitoring sites at airports can be extremely challenging often with no power or telephone lines available and with limited access for maintenance. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited for this application. Installed at various locations around the airport, deployed with it’s own integrated anti-biofouling system, utilising the GSM network, the monitoring sites send data to a secure ftp site, where any internet enabled device can access the data. In this way the systems act as any early warning system allowing any hydrocarbon discharge to be detected in real-time.

Optional environmental monitoring features include remote control to allow the user to turn equipment on and off, change the sample rate and detection range. There is also a facility to allow SMS text and email alarm notifications triggered by user-defined set-points together with customised web pages, data displays and automated data downloads via an ftp server.

Airport runoff can contain high concentrations of various pollutants, in particular polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), the environmental levels of which have to be monitored. An understanding of the magnitude of contamination due to airport runoff water is important for the effective management of airport infrastructure. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited to the airport environment.

Oil in Water Analysis for Flowback or Produced Water

The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote lab results can take several days to a week. InfraCal TOG/TPH Analyzers allow for oil in water testing at the well site in less than 10 minutes. The sampling requires a few simple steps that can be performed by non-technical personnel. The water is mixed with the extraction solvent, shaken, and then presented to the analyze for measurement. The same InfraCal TOG/TPH Analyzer can be used for TPH in soil if a spill or pond leak occurs to determine the contaminated area. The analyzer features: -Results in under 15 minutes -Detect levels as low as 10 ppm -Portable, rugged, lightweight, easy-to-use -Battery operable -Ideal for field or lab use

Homeland Security

Safe Training Systems (STS) manufacture a range of simulated ionising radiation monitors suitable for use by homeland security departments. The range includes contamination and radiation simulators from manufaturers such as Ludlum, Rotem, TSA and Thermo. In particular instruments such as the Rotem Ram Gene 1 mk II and the TSA PRM470 CS are popular with UK services. US users still prefer instruments such as the Thermo RO2 and Ludlum 3 for their instrument training. STS offers a wide and versatile range but will also consider making instruments to users specifications. Please see our web site for full details at www.radiationsimulation.com
