Overview

A significant number of rivers in Wales are classified as moderate/poor quality and are termed “failing” in the context of aspirations for future water quality. Various impacts including those from legacy mining have long been known to be a primary factor, however, many engineering challenges complicate actions to improve water quality status.
 
While “modern” active water treatment technologies can be considered an “efficient” solution on the basis of cost, consideration of sustainability and “green credentials” is becoming increasingly important with an industry focus on environment and social governance (ESG) and decarbonisation. So-called “passive” treatment systems (e.g. wetlands) have thus attracted much interest as they purport to be more aligned with ESG metrics. However, “passive” treatment options often require active management/replenishment over the longer term. If true life cycle sustainability is to be assessed, then a more holistic view is required. 
 
A case study is provided from Mine Environment Management’s work with NRW in Wales, and will discuss emerging technologies that provide an alternative approach, termed Sustainable Active Treatment (SAT). A more holistic/whole life cycle methodology is considered along with a more nuanced view of the term’s passive and active treatment.

This event is being organised by the Wales Cymru N Wales / GSAT Webinar.
