Wastewater treatment employees may be exposed to HAV from contact with the working surfaces, water, or air throughout various stages of the wastewater treatment process. This study examined working surfaces at a wastewater treatment plant for the presence or absence of HAV. The areas assessed by swab samples (3M Enviro Swabs) were similar to those of a prior study and included door handles, bin handles, and railings in the preliminary treatment building (screens) and grit channels. A lunchroom and control location were also sampled. The locations were identified as those with the highest potential for splash of wastewater and in places employees routinely spend time. One influent sample was also collected daily. The study was conducted over three days, two weekdays and one weekend day. All surface and water samples were sent to a laboratory in Cincinnati, Ohio for qualitative detection of Hepatitis A Virus. HAV was detected/100mL in one of three influent samples. All swab samples were negative for HAV. Future studies may use a wipe or other alternative sampling approach since adherence and recovery of viral materials from swabs is difficult. Employees should receive training on HAV to include information on the health effects and infectivity of HAV, appropriate hygiene practices, and proper personal protective equipment. 2018 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1533208035412584 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1533208035412584 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
