I welcome the witnesses. It has been said of the water quality monitoring report the EPA has done that the agency concludes that the average nitrates concentration has increased since 2012-13. Claims have been made that this is not supported by any data. How has the EPA reached its conclusion if the data do not exist? Dr. Cotter spoke about trends and so on but data should be used here across the board. Is the report based on data or are there data missing here that we should know about?
