soil contamination monitoring Applications

By Modern Water - Monitoring Division based in Cambridge, UNITED KINGDOM.

Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.

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.

The Sorbisense method allows for measuring the average concentration of substances in groundwater over a period of up to 1 month with only one sample.

The system provides methods for measurements in both unsaturated and saturated zone and provides access to dynamic boundaries of contaminants and more realistic risk assessments. For example, through direct measurements of seepage from contaminants and by continuous measurement of emissions from cropland.

Overview

Being able to trust your instruments to make quick, easy and accurate measurements in the field is key when dealing with regulatory requirements. The InfraCal2 infrared analyzer is the choice of experts for measuring oil in produced water; oil contamination in soil; and fats oil and greases in waste streams.

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

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.

With the growth of contamination generated from agricultural and industrial production, it causes a threat to the enviroment including drinking water, atmosphere and soil. The chemists have always seeked out the effective analytical methods to detect and identify chemical contaminants. Dikma provides innovative products and application solutions according to government regulations and industry standards, for air and water quality monitoring, gas detection.

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.
