The U.S. Environmental Protection Agency recently released a report  that assessed likely sources of nitrate pollution - including dairy farms and crop fields - in lower Yakima Valley groundwater and some drinking water wells. Scientists sampled more than 300 wells and found up to 20 percent had high nitrate levels.They concluded that dairies were the most likely source of the contamination.

Nitrates come from manure and fertilizers. When they contaminate drinking water, nitrates can be harmful to children and some adults.

Some Yakima Valley dairy farmers, public officials, and agriculture experts have taken issue with the report.

Local dairy farmer Jason Sheehan and Steve George, President of the Yakima Farm Bureau were guests on Thursday's Mike Bastinelli show. They talked about the report, and how they see it as a threat to the dairy industry.
