Non Technical Summary
From the NADP web site:The National Atmospheric Deposition Program (NADP) monitors precipitation chemistry.The program is a cooperative effort between many different groups, including federal, state, tribal and local governmental agencies, educational institutions, private companies, and non-governmental agencies.HistoryIn 1977, U.S. State Agricultural Experiment Stations (SAES) organized a project, later titled the National Atmospheric Deposition Program (NADP), to measure atmospheric deposition and study its effects on the environment.Sites in the NADP precipitation chemistry network began operations in 1978 with the goal of providing data on the amounts, trends, and geographic distributions of acids, nutrients, and base cations in precipitation. The network grew rapidly in the early 1980s. Much of this expansion was funded by the National Acid Precipitation Assessment Program (NAPAP), established in 1981 to improve understanding of the causes and effects of acidic precipitation. Reflecting the federal NAPAP role in the NADP, the network name was changed to NADP National Trends Network (NTN). Today, the NADP is SAES National Research Support Project - 3. The NTN network currently has 263 sites.-----We are conducting standard NADP operations at a single network node, the site known as Palo Duro Canyon State Park (site code TX43), 25 miles southeast of Amarillo, TX.

Goals / Objectives
Characterize geographic patterns and temporal trends in chemical or biological atmospheric (wet and dry) deposition Support research activities related to: (a) the productivity of managed and natural ecosystems; (b) the chemistry of surface and ground waters, including estuaries; (c) critical loads in terrestrial and aquatic ecosystems; (d) the health and safety of the nationâ¿¿s food supply; and (e) source-receptor relationships

Project Methods
Weekly collection of rainfall samples in a 5-gallon, plastic bucket using specialized samplers with rainfall detectors. Weekly measurement of precipitation using a continuous, weighing rain gauge. Transmission of rainfall data to NADP headquarters via email. Independent corroboration of cumulative, weekly rainfall depth by tare-weighing the rainfall sampler bucket. Sterile submittal (i. e., to the NADP laboratory) of precipitation sample in 32 oz. wide-mouth Nalgene sample bottle via United States Postal Service.

Progress 06/30/20 to 09/30/20

Outputs
Target Audience:Agricultural producers, livestock producer associations, and policy makers concerned with atmospheric deposition of inorganic macronutrients. Changes/Problems:Field campaigns to measure fugitive dust and dry deposition from livestock facilities have been paused during the COVID-19 pandemic to reduce respiratory stress on our agency's employees. No change in routine PAL190/TX43 operations, however. What opportunities for training and professional development has the project provided?Technicians and Senior Research Associate are learning to design experimental apparatus to measure the effects of low relative humidity and high solar-ultraviolet intensity on the viability of dust-borne, dry-deposited bacteria carrying antimicrobial-resistance markers. How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?(1) Additional field campaigns to measure AMR-expressing bacteria in dry-deposited, fugitive dust from livestock facilities. (2) Continued management and operation of PAL190/TX43 deposition site at Cañonceta, TX.

Impacts
What was accomplished under these goals? (1) Continued excellent data return to both NADP and CASTNET networks. (2) Awarded a $151,500 grant from the USDA-NRCS Conservation Innovation Grants (CIG) program to help mitigate nitrogen deposition from livestock operations into Rocky Mountain National Park. (3) Characterizing and quantifying near-field, dry deposition of bioaerosols downwind of open-lot livestock facilities.
