However, this could expose individuals to respiratory pathogens such as <jats:italic>Legionella pneumophila<\/jats:italic> and nontuberculosis <jats:italic>Mycobacteria<\/jats:italic> (NTM). Disinfection with methods like anaerobic digestion is an option but can increase concentrations of cytotoxic ammonia (personal communication). Our study aimed to model the annual risks of infection from these bacterial pathogens and the air concentrations of ammonia and determine if anaerobically digesting this wastewater is a safe option. Air dispersion modeling, conducted in AERMOD, generated air concentrations of water during the irrigation season (May\u2013September) for the years 2013\u20132018. These values fed into the quantitative microbial risk assessments for the bacteria and allowed calculation of ammonia air concentrations. The outputs of these models were compared to the safety thresholds of 10<jats:sup>\u22124<\/jats:sup> infections\/year and 0.5 mg\/m<jats:sup>3<\/jats:sup>, respectively, to determine their potential for negative health outcomes. It was determined that infection from NTM was not a concern for individuals near active spray irrigators, but that infection with <jats:italic>L. pneumophila<\/jats:italic> could be a concern, with a maximum predicted annual risk of infection of 3.5 \u00d7 10<jats:sup>\u22123<\/jats:sup> infections\/year and 25.2% of parameter combinations exceeding the established threshold. Ammonia posed a minor risk, with 1.5% of parameter combinations surpassing the risk threshold of 0.5 mg\/m<jats:sup>3<\/jats:sup>. These findings suggest that animal wastewater should be anaerobically digested prior to use in irrigation to remove harmful pathogens.<\/jats:p>","DOI":"10.1111\/risa.13607","type":"journal-article","created":{"date-parts":[[2020,10,21]],"date-time":"2020-10-21T03:54:48Z","timestamp":1603252488000},"page":"745-760","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Quantification and Comparison of Risks Associated with Wastewater Use in Spray Irrigation"],"prefix":"10.1111","volume":"41","author":[{"given":"Jameson","family":"Mori","sequence":"first","affiliation":[{"name":"Department of Pathobiology University of Illinois Urbana\u2010Champaign  Urbana IL USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sital","family":"Uprety","sequence":"additional","affiliation":[{"name":"Department of Civil &amp; Environmental Engineering University of Illinois Urbana\u2010Champaign  Urbana IL USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuqing","family":"Mao","sequence":"additional","affiliation":[{"name":"Department of Civil &amp; Environmental Engineering University of Illinois Urbana\u2010Champaign  Urbana IL USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sotiria","family":"Koloutsou\u2010Vakakis","sequence":"additional","affiliation":[{"name":"Department of Civil &amp; Environmental Engineering University of Illinois Urbana\u2010Champaign  Urbana IL USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5461-5233","authenticated-orcid":false,"given":"Thanh H","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Civil &amp; Environmental Engineering University of Illinois Urbana\u2010Champaign  Urbana IL USA"},{"name":"Carl R.
