Using sensors in environmental monitoring

Southern England - Environmental field teams spend significant time travelling between sites, not only driving up harmful carbon dioxide emissions, but also increasing health and safety risks from potential road traffic accidents. The use of networks of environmental sensors, which can transmit field survey information using telemetry, is having a real impact on improving quality of life by reducing the risk of road traffic accidents and cutting carbon dioxide emissions, while also resulting in a significant improvement in the quality and resolution of environmental survey data.

Using sensors in environmental monitoring

Environmental monitoring and sampling has traditionally been done by field surveyors visiting sites, taking measurements and submitting samples to laboratories for analysis. However, the huge advancement in environmental sensor technology now provides viable alternatives for many forms of monitoring and sampling in the field. 

In the case of an oil and gas land contamination site that was being assessed in the south of England, the use of environmental monitoring sensors - powered by solar energy and with the ability to transmit high resolution data remotely - led to a significant 60% reduction in miles travelled. 

The data collected included: 

  • Changing groundwater depths with time
  • Hazardous gas concentrations in the subsurface 
  • Thickness of liquid phase contamination in monitoring wells

This represented a 10,000% increase in the size of the dataset, for the same cost as a traditional survey approach. 

An online portal enabled everyone involved in the project to view the data in real-time. This supported the development and buy-in to a robust risk management strategy for this complex site from the many different stakeholders involved; another major benefit to the client.
