Jersey Water has announced 100% compliance in its water quality results for the 2021 business year. There were no instances of pesticides and nitrates exceeding the regulatory limits in treated water. In addition, the bacteriological compliance of water leaving the treatment works and treated water reservoirs achieved 100%.
For the eighth consecutive year, Jersey Water has successfully treated and maintained nitrate concentrations below the regulatory limit in drinking water through the careful selection and blending of water sources.
Throughout the year the Company completed 12,000 sampling tests on untreated water from streams, storage reservoirs and the inlet to our treatment works. 15,000 laboratory tests were taken on treated water from our water treatment works, in the mains network, and at the treated water reservoirs to monitor performance and ensure water quality compliance.
Julie Taylor, Jersey Water Operations Director, said, “We are delighted to have achieved 100% regulatory compliance for the supply of drinking water. This is a real team effort from across the entire business working seamlessly to ensure our processes are operating to the highest standards possible. We are particularly grateful to the Jersey farming community for their continued improvement and outstanding efforts to help protect water sources before it reaches our reservoirs. We are delighted to be sponsoring the Farming Conference 2021 at La Mare Wine Estate on Thursday 11th November.
“As part of the Action for Cleaner Water Group, we continue to work with the Government of Jersey and the farming community to deliver water quality improvements and protect the environment from pollution risks. Over the next year, we will increase our focus on proactive catchment management activities to monitor raw water quality to protect and safeguard our precious water sources.”
Jersey Water is part of the Technical Officer Group to resolve the issue of historic PFAS pollution in the St. Ouen’s Bay aquifer and Pont Marquet area. The drinking water supply in Jersey is fully compliant with the most stringent international regulatory quality standards for PFAS in drinking water. The Company monitors the level of PFAS in the affected water sources as part of its comprehensive sampling and analysis programme to ensure that the water meets the most rigorous standards by a comfortable margin.
