Determination of the pH value provides information about the acid or base action of the soil solution. This in turn is enormously important for the nutrient supply and microbial activity of the soil. For example, many metals (trace elements) are considerably more mobile in acidic soils. If the soil pH values are very low, toxic levels can soon be reached and these can damage the roots of plants. On the other hand, excessively high pH values quickly lead to a shortage of trace elements because of immobilization.<...

Low flow groundwater sampling is a methodology used around the world to simulate ambient flow conditions and take water quality readings. A wide variety of pumps are used to draw a sample from the well such as bladder, inertial or peristaltic pumps and usually combined with a flow controller. Once the sampling methodology for your site has been selected, then choosing the right multi-parameter probe is vital.

The reasons for testing water quality in groundwater are numerous. Monitoring water quality and conducting tests is a good way to gather data on aquifer hydraulics. It can also be used to monitor parameters such as rhodamine, which helps to understand movement of underground water. Human activities can have an impact on groundwater quality, and conducting tests in this field can help to track these effects. Leachate from landfill and fertiliser can both find their way into groundwater. It is important to...

InfraCal TOG/TPH Analyzers allow for TPH (Total Petroleum Hydrocarbons) in soil testing at remediation sites such as leaking underground storage tanks and produced water evaporation ponds. Site managers can avoid having costly soil remediation equipment sit idle while waiting for off-site lab results. Sampling requires a few simple steps that can be performed by non-technical personnel. The soil is mixed with the extraction solvent, shaken, filtered, and then presented to the InfraCal Analyzer for measurement....

Over the past few decades, soil monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related to soil hydrological processes. Monitoring soil moisture conditions provides important information for the protection of, and in the understanding of local and...

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.

The migration of magma towards the surface in a volcano is usually accompanied by the release of gas that was previously dissolved in the magma itself. In an open conduit volcano, most of the gas escapes through the main conduits of the volcano and then through the craters. However, a significant proportion (approximately 10%) of the total quantity of gas can escape laterally through faults and fractures that are normally present in the flanks of a volcano. Therefore, increases in the amount of gas emitted...
