Chemical Investigations Programme: where are we now?
About Ruth Barden
Ruth Barden has over 20 years experience in the water industry, particularly focussed on environmental and wastewater aspects. Ruth leads Wessex Water’s environmental investigation programme, catchment partnerships and environmental policy. This involves elements of research, innovation and a high degree of collaboration with a wide range of stakeholders.
The water industry has been collaboratively delivering the Chemical Investigations Programme since 2010, furthering our understanding of the occurrence and fate of substances in sewage. We can characterise sewage effluent and have tested a number of existing and novel treatment technologies to understand their removal performance and costs. Over this time period we have also seen a decline in the concentrations of certain substances. However, new substances of concern are emerging which need further investigation.
