Household water quality checks to resume following easing of lockdown June 28, 2021, 12:01 am Water quality sampling checks are set to re-start at households across the country after a year-long halt due to the coronavirus pandemic. Scottish Water samplers will once again be carrying out checks at randomly selected addresses to ensure the water Scottish customers use meets high quality standards. Nationwide household sampling has been paused during the pandemic to help prevent the spread of the virus and keep employees and customers safe and healthy. However, alternative sampling arrangements, which were agreed with the Drinking Water Quality Regulator (DWQR), were put in place to monitor quality levels throughout the past year.
