The quality of bathing water around the South West coastline has come under increasing scrutiny in recent years.
With concerns over public and environmental health rising, a new project is looking to develop a remote, faster and more efficient means of testing the region's seas and alerting authorities to any potential health hazards that are discovered.
The new initiative is being developed by Molendotech Ltd and the University of Plymouth, who between them have considerable expertise in marine autonomous systems and advanced water testing technologies.
Its aim will be to offer remote near real-time water quality assessments through an autonomous water sampling and testing device that builds on existing technology already developed by the project partners.
The project will leverage the use of Bacterisk, a near real-time bacteria risk assessment kit that provides an assessment of water quality in 15 minutes (instead of other methods that currently take longer than 48 hours) and adapt it to allow the remote assessment of water quality.
In Devon and Cornwall, there are 150 bathing water sites and monitoring the water quality of all the coast in near real time would be challenging and costly.
Bacterisk is already being used by water utilities and other stakeholders in the UK to reduce the risk of public health for water users as current methods deliver a late response and are not adequate at protecting the health of the population.
The new system could allow water samples to be collected from the seabed to the surface as frequently as every 30 minutes. The results would then be communicated automatically to those responsible for identifying and managing public health issues.
