He said the sample site looked clean and the residual was 0.94 mg/l. 3 repeat samples will be taken today, 1 at the original site, 1 within 5 connections upstream and 1 within 5 connections downstream. He asked if he had to call us back if the repeat samples were clean and I said no, only if they are positive.
