Haverhill to Newburyport Water Quality Data

Volunteers Doug Clinch, Captain Lew Zediana and Emily Sullivan brave all kinds of weather to gather monthly samples for the Merrimack River Watershed Council. The eight samples, plus one duplicate sample, are gathered from a boat belonging to Lew. YSI measurements are also taken at each site with a duplicate measure taken at a randomly chosen depth each time. The data from June 27, 2013 is represented below.
