The NADP site LA30 is located at the LSU AgCenter Southeast Research Station which is approximately 100 kilometers north of New Orleans, LA. This marks the 31st year for the site to be part of the NADP program, a national program that has been in existence for 36 years. The LA30 site successfully monitored weekly rainfall precipitation and forwarded the samples and data to the national headquarters at the University of Illinois. The data from the LA30 site and the other 265 sites nationwide was compiled into national and regional summaries for total precipitation, nitrate, sulfate, ammonium ion, pH, magnesium, calcium, chloride, bromide and mercury. The summary publication indicated that Louisiana is in the top 10% for rainfall (>160cm) and sulfate deposition (>10kg/ha). However, Louisiana has been and continues to be low to moderate in nitrogen, chloride, calcium and magnesium and bromide deposition. As with most of the coastal states and parts of the lower Mississippi River Valley, mercury deposition was high (>18ug per square meter). The pH of the precipitation was a 5.1 for the Louisiana site which is similar to most sites east of the Mississippi River and has not increased appreciably over time. These trends, when compared to historic levels. Indicate an improvement in precipitation quality as most modern industries have implemented methods and new technologies to prevent pollutants from entering the environment.

The NADP site, LA30, is located at the LSU AgCenter Southeast Research Station approximately 100 kilometers north of New Orleans, LA. The site completed its 30th year in the NADP program, a national program that has been in existence for 35 years.Weekly rainfall precipitation was monitored with water samples and data forwarded to the national headquarters at the University of Illinois. Results were compiled into regional and national trend summaries for total precipitation, sulfate, nitrate, ammonium ion, pH, magnesium, calcium, chloride, bromide and mercury. Ofthe 260 national sites, the summary indicates that Louisiana is in the top 10% in rainfall (>160cm) and chloride/ sulfate deposition (>10kg/ha), However, it is low to moderate in nitrogen, calcium, magnesium and bromide deposition. As with most coastal states, mercury deposition was high (>18 ug per square meter). At a pH of 5.0, precipitation acidity was similar to most sites east of the Mississippi River.These trends, when compared to historic levels, suggest an improvement in precipitation quality as more industries strive to remove pollutants from the environment.The accracy of data collection will be enhanced in 2014 with the implementation of new digitally automated equipment at the LA30 site.

Outputs
OUTPUTS: LA30 site reports are prepared monthly to document local precipitation type, amount and chemistry. The National Atmospheric Deposition Program (NADP) also publishes an annual summary that contains average precipitation and chemistry for all 115 sites throughout the US (including Alaska and Puerto Rico). This data is being used by state and federal agencies, universities, policy makers, primary and secondary schools and others to make informed decisions on environmental issues related to precipitation, deposition chemistry and atmospheric mercury trends. The data is also available via the web site http://isws.illinois.edu. PARTICIPANTS: Mike McCormick (PI), Jerry Simmons, LSU AgCenter. TARGET AUDIENCES: state and federal agencies, universities, policy makers, primary and secondary schools PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
The NADP site LA30 is located at latitude 30.7819, longitude 90.2021 on the Louisiana State University Agricultural Center's Southeast Research Station near Franklinton, LA. The station is located approximately 100 kilometers north of New Orleans. The National Trends Network is the largest North American network that provides a long-term record of precipitation chemistry for the U.S. According to the most recent NADP summary, precipitation at site LA30 in Louisiana may be characterized as moderately high in volume (110-130 cm), low in nitrites, nitrates, ammonium ion and calcium and moderately high in chloride. Average precipitation pH was 4.9 which is typical of precipitation from most Gulf Coast states. In general, precipitation east of the Mississippi River had a pH of less than 5.0 while west of the river pH values were less acidic ranging from 5.3 to 6.3. Nitrogen deposition was relatively low at this site (3.8 kg/ha) compared to that recorded in Midwestern states which was over 8.0 kg/ha at many sites. Although not assayed at this site, data from Mississippi and Florida sites indicate that precipitation in Gulf Coast States contains some of the highest levels of mercury in the U.S. (15-20 microgram/square meter). Currently, the NADP site LA30 is the only Louisiana NADP site that is participating in the National Trends Network that provides a long term record of precipitation chemistry.

Impacts
The NADP site LA30 is located at latitude 30.7819 and longitude 90.2021 on the Louisiana State University Agricultural Center's Southeast Research Station near Franklinton, LA. The station is located approximately 100 kilometers north of New Orleans. In the spring of 2011, a new more remote site was selected on the Southeast Research Station for the NADP equipment. The site was moved due to construction of an asphalt plant close to the original site. Solar panels and new equipment were installed. Automated precipitation collection equipment is visited weekly, and total precipitation and a precipitation event chart are collected. A precipitation form is used to record total precipitation weight, precipitation in cm, contaminants, etc. A subsample of precipitation equaling approximately one liter is mailed to the Central Analytical Laboratory at the University of Illinois. According to the most recent NADP summary, precipitation at site LA30 in Louisiana may be characterized as moderately high in volume (125-150 cm), low in nitrites, nitrates and calcium, and moderately high in chloride. Average precipitation pH was 4.9 which is typical of precipitation from most Gulf Coast states. In general, precipitation east of the Mississippi River had a pH of less than 5.0 while west of the river pH values were less acidic, ranging from 5.3 to 6.3. Nitrogen deposition was relatively low at this site (2.8 kg/ha) compared to that recorded in Midwestern states which was over 7.0 kg/ha at many sites. Although not assayed at this site, data from Mississippi and Florida sites indicate that precipitation in Gulf Coast States contains some of the highest levels of mercury in the US (15-20 microgram/square meter).

Outputs
OUTPUTS: Weekly precipitation amounts and precipitation chemistry from this National Atmospheric Deposition Program (NADP) site (LA30) were included in an annual summary that provided precipitation averages and precipitation chemistry for 115 sites throughout the US. This data is being used by state and federal agencies, universities, policy makers, primary and secondary schools and others to make informed decisions on environmental issues related to precipitation, deposition chemistry, and atmospheric mercury trends. The data may be accessed via the web site http://isws.illinois.edu. PARTICIPANTS: Jerry Simmons, NADP site LA30 technician. Mike McCormick, NADP site LA30 administrator. In 2010 the other Louisiana NADP site at the New Iberia Station in south central Louisiana was closed. Currently, the LA30 site near Franklinton, LA is the only Louisiana NADP site particpating in the National Trends Network that provides a long-term record of precipitation chemistry. TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

The NADP site LA30 is located on the Louisiana State University Agricultural Center's Southeast Research Station near Franklinton, LA. The station is located approximately 100 kilometers north of New Orleans, LA. Automated precipitation collection equipment is visited weekly and total precipitation and a precipitation event chart are collected. A precipitation form is used to record total precipitation weight, contaminants, etc. and a sub-sample of precipitation equaling approximately one liter is mailed to the Central Analytical Laboratory at the University of Illinois. According to the most recent NADP summary, precipitation in southeastern Louisiana may be characterized as low in ammonium, nitrate, and sulfate concentrations but moderately high in mercury concentrations, as is most of the Gulf Coast region. Total annual precipitation for this site was 122.89 cm in 2010 with an average pH of 5.0. Annual precipitation was about 15% lower than historical averages due to unusually low (<2 cm) rainfall in September, October, and December 2010. The collection equipment at this site will be replaced with new more efficient digitized monitors in the spring of 2011 and a new more remote site (consistent with NADP guidelines) established at the Southeast Research Station. The project was renewed for another five years on October 1, 2010.
