Between July 30th - August 4th, 2009, 13 EPA scientists worked aboard the OSV Bold on a nutrient survey from Boston Harbor to Penobscot Bay in midcoast Maine. You can read through the attached web archive to see the daily plan and data results.
Overall, EPA collected approximately 200 water samples in coastal Massachusetts, New Hampshire and Maine, with special attention in Penobscot Bay, Massachusetts Bay and southern Maine. Analyzing these samples helps tell us about how healthy this coastal water is, and if we are doing the right things to protect the environment.
Figure 1. The anticipated sample stations are plotted on this map.
Based on water sampling that was done in 2004 and 2005, EPA will revisit those areas to compare past results with current water quality conditions. EPA will sample stations R1-1 through R1-25, plus additional areas within Penobscot Bay if time allows.
