Ecologia has recently carried out a field trial of our Autonomous LNAPL Monitoring System (ALMS), at a former oil refinery in Northern Europe. Near-continuous data were recorded over a number of days. The ALMS was able to operate for an extended period of time without operator input, and record the level of the LNAPL and groundwater every ten seconds. The accuracy and precision were such that the small movements in fluid levels as a response to rainfall were able to be tracked. These were picked up by the system automatically, and verified using an interface probe.
In addition to providing high-quality data, the system removes the need for continuous operator presence. Risks to staff are minimised, dramatically lowering health and safety concerns. In addition, the system removes the need to disrupt any site operations, reducing the logistical burden on site owners and operators.
