Jersey Water is currently evaluating various methods to reduce per- and polyfluoroalkyl substances (PFAS) in its water supply, with results from ongoing tests expected next year. The utility's chief executive officer, Helier Smith, indicated that the construction of a new treatment plant, if deemed necessary, could incur costs of up to £210 million.
Smith warned that such an expenditure could lead to a substantial increase in customer bills, potentially raising them by 70% to 110%. "Nobody wants that, especially Jersey Water," he stated, emphasizing the goal of finding a "proportionate and cost-effective" solution that minimizes the impact on bills.
A scientific panel's final report has recommended that Jersey Water adhere to lower levels of PFAS. However, the utility's cost projections have been met with skepticism. Ian Cousins, an environmental expert advising the panel, suggested that the £210 million figure might be an "exaggeration." Cousins noted that tackling PFAS in other regions has often been achieved by retrofitting existing water treatment facilities rather than building entirely new ones, and he believes a lower-cost approach is feasible.
Ministers are expected to provide a more detailed response to the panel's report later this year. The timeline for implementing measures to address PFAS in other locations has typically ranged from three to five years, according to Cousins. The exact source of PFAS contamination on the island has been linked to areas such as Jersey Airport's training grounds, as shown in aerial imagery.
The discussion around the cost and feasibility of PFAS treatment highlights a broader challenge faced by water utilities worldwide. These synthetic chemicals, often referred to as 'forever chemicals,' are persistent in the environment and have been linked to various health concerns. The potential financial burden on consumers in Jersey underscores the complex trade-offs between environmental protection and affordability.
