Microplastics and the New Definition of Water Purity
Microplastic particles have emerged as a significant class of environmental contaminants in recent years. Defined as micro plastic particles smaller than 5,000 µm but larger than 1 µm they are now widely detected across marine and terrestrial ecosystems, as well as in drinking water and biological samples. Although their long-term health implications are still being investigated, early studies indicate potential associations with inflammatory responses, cellular stress, and broader biological interactions.

In environmental testing, detecting PFAS is tricky. Measuring compounds at single digit parts-per-trillion (ppt) or sub-ppt levels leaves little room for error, yet some of the biggest risks don't come from the sample itself, but from the laboratory environment.

Upgraded telemetry technology helped Dŵr Cymru Welsh Water manage an unprecedented volume of alarms during a major weather event, writes Julian Booth, SCADA service delivery manager, Ovarro.

Xylem is proud to be one of the partners in the The River Deep Mountain AI (RDMAI) project. This is a collaborative, open-source initiative led by Northumbrian Water. The open-source release of a suite of artificial intelligence and machine learning (AI/ML) models is set to transform the way water quality data is collected and used.
