1987: Rochester Embayment 'Area of Concern' created to improve public health

"Biomonitoring of Great Lakes Populations Program by the Toxic Substances and Disease Registry and the Department of Health and the Department of Health and Human Services" This was the original intent of identifying 'areas of concern'.

Not so much about the 'black tern. 

From the Federal Register Volume 76, Number 214 (Friday, November 4, 2011):; 

In 2009, the Great Lakes Restoration Initiative (GLRI) was enacted as Public Law 111-88. The GLRI makes Great Lakes restoration a nationalpriority for 16 Federal agencies. The GLRI is led by the U.S. 

Environmental Protection Agency (US EPA). Under a 2010 interagency 
agreement with the US EPA, the Agency for Toxic Substances and Disease 
Registry (ATSDR) announced a funding opportunity called the 
``Biomonitoring of Great Lakes Populations Program'' (CDC-RFA-TS10-
1001).
    This applied public health program aims to measure Great Lakes 
chemicals in human blood and urine. These measures will be a baseline 
for the GLRI and future restoration activities. The measures will be 
compared to available national estimates. This program also aims to 
take these measures from people who may be at higher risk of harm from 
chemical exposures.
    Three states were funded for this program: Michigan, Minnesota, and 
New York. The health departments in these states will look at seven 
AOCs and four types of sensitive adults: Michigan--urban anglers in the 
Detroit River and the Saginaw River and Bay AOCs; Minnesota--American 
Indians from the Fond du Lac Community near the St. Louis River AOC; 
and New York--licensed anglers and immigrants from Burma and their 
family members living in four Lake Ontario and Lake Erie AOCs. These 
include the Rochester Embayment AOC, the Eighteenmile Creek AOC, and 
the AOCs along the Niagara and Buffalo Rivers.
