Roosevelt Campobello International Park Air Quality Information
Overview
No wet deposition monitoring is conducted at Roosevelt Campobello International Park. A National Atmospheric Deposition Program/National Trends Network (NADP/NTN) wet deposition monitor has been operating at Acadia NP, 75 miles southwest of Roosevelt Campobello International Park, since 1981 (site #ME98). Site data show a decrease in concentration and deposition of wet sulfate; no overall trend in concentration and deposition of wet nitrate; and no overall trend in concentration and deposition of wet ammonium. A Canadian Air and Precipitation Monitoring Network (CAPMoN) site has been operating at Kejimkujik National Park (site #KEJ) in Nova Scotia, 95 miles southeast of Roosevelt Campobello International Park, since 1983. A review of 1984 through 1998 data shows no overall trend in concentration and deposition of wet nitrate or sulfate deposition at the site.
No dry deposition data are collected at Roosevelt Campobello International Park. A Clean Air Status and Trends Network (CASTNet) dry deposition site has been located at Acadia NP (site #ACA416) since 1998. The site has not been operating long enough to detect trends in dry deposition.
Ozone has been monitored seasonally at Roosevelt Campobello International Park since 1995 through a joint effort of Environment Canada, the Maine Department of Environmental Protection and the park. Data help provide real time maps of ozone concentrations throughout the northeast U.S. and Atlantic Canada. Data indicate no monitored exceedances of the human health based 1-hr National Ambient Air Quality Standard (NAAQS) or calculated exceedances of the new 8-hr NAAQS.
Plant species with documented sensitivity to ozone occur in Roosevelt Campobello International Park. To date, plants in the park have not been examined for ozone injury.
Visual air quality is not monitored in Roosevelt Campobello International Park. However, as part of the Interagency Monitoring of Protected Visual Environments (IMPROVE) network monitoring strategy, the aerosol sampler at Moosehorn National Wildlife Refuge (NWR), Maine, a Class I air quality area, is intended to represent conditions at Roosevelt Campobello International Park. The aerosol sampler at Moosehorn NWR (site #MOOS1) has been operating since 1994. 1996-1998 site data show that, in terms of the sources of visibility impairment, Moosehorn NWR data are consistent with those from other eastern U.S. IMPROVE sites. The data show that, on an annual basis, visibility impairment is primarily due to sulfates (sources include coal combustion and oil refineries), then organics (sources include automobiles), then nitrates (sources include coal and natural gas combustion and automobiles), then light absorbing carbon (sources include wood burning), then soil (from windblown dust). The U.S. Environmental Protection Agency’s new Regional Haze regulations require improving visibility in Class I air quality areas on both the best visibility and the worst visibility days. Long-term trend data are not yet available for the Moosehorn NWR site. Data have been collected at Acadia NP long enough to assess trends. Unfortunately, the data show that views at the park on the best, worst, and average visibility days decreased between 1988 and 1998.
