The draft Private and Public Water Supplies (Miscellaneous Amendments) (Scotland) Regulations 2015 amend the Private Water Supplies (Scotland) Regulations 2006 and the Public Water Supplies (Scotland) Regulations 2014 with the aim of further protecting human health from the adverse effects of any contamination of water for human consumption purposes.
In particular, they set out the general principles and monitoring frequencies, specifying in more detail the requirements in relation to radon, tritium and indicative dose, screening strategies, calculation of indicative dose and analytical performance characteristics. As required by the Directive, they set a threshold value for radon which if exceeded would require an assessment of whether there is any risk to human health. The Directive states that the level set may be higher than 100 Bq/l but lower than 1,000 Bq/l. The draft regulations set the threshold value at 100 Bq/l.
The regulations do not transpose the new Directive with regard to bottled drinking water for sale, which is transposed in other legislation.
