This is the third report on the Cumberland Piedmont Network's (CUPN's) efforts to monitor both ozone and ozone's associated foliar injury generated by the CUPN. This report includes data collected in calendar year (CY) 2010, displays results in tabular and graphic form (accompanied by a brief interpretation) and concludes with a summary of the key results and recommendations. The CUPN's ozone and foliar injury efforts in CY2010 focused on three parks: Chickamauga and Chattanooga National Military Park (CHCH), Mammoth Cave National Park (MACA) and Stones River National Battlefield (STRI). Since these parks were where efforts were focused on in CY2010, they will be hereafter referred to as the "focus parks". Results presented in this report are primarily based on data collected at these three parks.

The National Park Service's (NPS) Organic Act of 1916 states that the mission of the NPS is to promote and regulate the use of national parks, monuments, and other units "... to conserve the scenery and the natural and historic objects and wildlife therein and to provide for the enjoyment of the same in such a manner and by such means as will leave them unimpaired for the enjoyment of future generations." One task embodied by this mission is preserving and protecting water resources and water dependent environments in parks. Ensuring the integrity of park water quality, due to its importance in sustaining natural, aquatic park ecosystems and supporting human consumptive and recreational use, is fundamental to successfully addressing this task. The first step in ensuring the integrity of park water quality is defining historic and extant water quality.
