On 5/20/20, WDNR has decided to change the Copper and Lead compliance sampling window for MUNICIPALITIES from June 1st through Sept 30th NOW TO July 1st through October 31st due to COVID-19. If you have not received bottles for this sampling yet, we have adjusted those orders to ship a month later. NNs and OTMs compliance sampling window will remain the same from June 1st through Sept 30th
