Average concentrations in 2014 for Ammonium (mg/lP) in samples from monitoring locations on the Irish Environmental Protection Agency Water Framework Directive (WFD) Groundwater Monitoring Network.

This is USDA-ARS data from the publication, "Characterization of particle size distributions and water-soluble ions in particulate matter measured at a broiler farm." This study was conducted in June of 2018. Data included here are from several measurements: Gas-phase ammonia measurements measured by an electrochemical sensor (Cairpol) in part-per-billion (ppb) with 1 minute time interval. Particle number concentration inside and outside the house measured by two optical particle counters (MetOne) in number per cubic centimeter (mg/cc) with 20 second interval. Particles were measured from 0.5-10 micrometers in 8 size bins. Particle number concentration measured by a scanning mobility particle sizer (TSI) and given as the differential number per size bin over 80 bins from 10-500 nanometers with a 5 minute time interval. Water-soluble ions in particulate matter measured by an ambient ion monitor (URG) measured in microgram per cubic meter with a 1 hour time interval.

Across the United States, high levels of ammonia in drinking water sources can be found. Although ammonia in water does not pose a direct health concern, ammonia nitrification can cause a number of issues and reduce the effectiveness of some treatment processes. An innovative biological ammonia-removal drinking water treatment process was developed and, after the success of a pilot study, a full-scale treatment system using the process was built in a small Iowa community. The treatment plant included a unique aeration contactor design that is able to consistently reduce ammonia from 3.3 mg of nitrogen/L to nearly nondetectable after a biofilm acclimation period. Close system monitoring was performed to avoid excess nitrite release during acclimation, and phosphate was added to enhance biological activity on the basis of pilot study findings. The treatment system is robust, reliable, and relatively simple to operate. The operations and effectiveness of the treatment plant were documented in the study. This dataset is associated with the following publication: Lytle , D., D. Williams , C. Muhlen , M. Pham , K. Kelty , M. Wildman, G. Lang, M. Wilcox, and M. Kohne.

This is a compilation of logs and data from Well 9-1 in the Roosevelt Hot Springs area in Utah. This well is also in the Utah FORGE study area. The file is in a compressed .zip format and there is a data inventory table (Excel spreadsheet) in the root folder that is a guide to the data that is accessible in subfolders.
