These Regulations apply in England in relation to private supplies of water intended for human consumption and specifically concern monitoring requirements for radioactive substances in water. They transpose requirements of Council Directive 98/83/EC on the quality of water intended for human consumption and Council Directive 2013/51/Euratom laying down requirements for the protection of the health of the general public with regard to radioactive substances in water intended for human consumption. They apply private supplies of water intended for human consumption, which mean supplies of water other than a supply provided directly by a water undertaker or licensed water supplier. The Regulations, among other things: define wholesomeness in relation to private water supplies; impose a duty on the local authority to carry out a risk assessment of the private water supply; set out the specific monitoring requirements for radioactive substances; set out sampling and analysis requirements; set out the procedures that apply if a private water supply is unwholesome or is a potential danger to human health.
