Simulated Pathogen Concentrations in Locally-Collected Greywater and Wastewater

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: August 02, 2025 | Last Modified: 2016-08-17
This dataset contains simulated pathogen concentrations in locally-collected greywater and wastewater. Each .zip file includes 21 .csv files, each containing 10,000 years of simulated daily pathogen concentrations in the water type designated by the title (Combined Greywater, Laundry Greywater, Shower Greywater, Sink Greywater, or Onsite Wastewater). Each .csv file corresponds to one pathogen (Ad Adenovirus, Ca Campylobacter, Cr Cryptosporidium, Gi Giardia, No Norovirus, Ro Rotavirus, or Sa Salmonella) for one population size (5-, 100-, or 1000-person). For example, ConcAdCombGW100.csv contains concentrations (Conc) of Adenovirus (Ad) in combined greywater (CombGW) for a 100-person population size (100). Data is structured as 365 rows (days) by 10,000 columns (years), with the first row and column containing year and day indices, respectively. Units are # pathogens/L water. This dataset is associated with the following publication: Jahne, M., M. Schoen, J. Garland, and N. Ashbolt. Simulation of enteric pathogen concentrations in locally-collected greywater and wastewater for microbial risk assessments. Microbial Risk Analysis. Elsevier B.V., Amsterdam, NETHERLANDS, 5: 44-52, (2017).
