Highlights: The USGS and NADP collaborated on the measurement of radionuclides (Iodine-131 3Cesium-134, and Cesium-137) in wet-deposition samples following the incident at the Fukushima Dai-ichi nuclear power plant in March. Results of the study were published in the journal Environmental Science & Technology and in a USGS report. Further information regarding the study is available on both the USGS and NADP websites. See http://bqs.usgs.gov/fukushima/ and http://nadp.isws.illinois.edu/fukushima/. The 2011 National Acid Precipitation Assessment Program (NAPAP) Report: An Integrated Assessmentwas presented to the U.S. Congress. This report featured data from the NADP networks. Bromide was approved as a new analyte for NTN and AIRMoN. Data will be available in 2012. NADP data and maps were used in more than 170 scientific publications. NADP was represented at the “World Acid Rain Conference” in Beijing, China. This conference is held every five years. NADP attended the “Mercury 2011” conference in Halifax, Nova Scotia, Canada. This interna-tional conference is held biannually and focuses on mercury as a global pollutant. 33 new sites were added to the AMoN. The NADP continued its support of the European directed Global Mercury Observation System (GMOS), and supported a new East Asia initia-tive for atmospheric mercury monitoring. NADP procedures for both field operations and data quality were adopted by GMOS. NADP serves on the Scientific Advisory Board of GMOS. Installation of electronic precipitation raingages at NADP wet-deposition sites continued (see map on page 4). At the end of 2011, 251 sites out of 290 total sites were operating with the new raingage. This represents 80% of the wet-deposi-tion network. NADP participated in the Prairie Research Institute’s Naturally Illinois Expo at the University of Illinois. The Expo is attended by K-12 students throughout Illinois.
