DESCRIPTION:Program: One Health Session: One Health Poster Session 2b: Var
 ious One Health Topics Presenter : Kei Kohmoto Abstract Transient non-com
 munity (TN) systems are public water systems that serve more than 25 peop
 le for 60 or more days a year\, including restaurants\, gas stations\, an
 d campgrounds. These systems must meet drinking water quality standards u
 nder the Safe Drinking Water Act\, complicated by seasonal operations and
  varying maintenance practices. These standards are set by the Wisconsin 
 Department of Natural Resources\, which has primacy from the EPA to do so
 . This work examined compliance and water quality issues in south central
  Wisconsin\, a region with nitrate contamination concerns linked to agric
 ultural land use practices.We conducted inspections of over 80 TN systems
  in south central Wisconsin from June through August of 2025. Inspections
  evaluated physical infrastructure\, including well casings\, conduits\, 
 treatment systems\, and pressure tanks for quality status and potential c
 ross-contamination sources. Combined with assessing nitrate concentration
 s and total coliform presence (which can be an indicator of e. coli)\, we
  evaluated compliance with the SDWA. Though violations were not common\, 
 when found\, the most common are damaged conduits (often from lawn mainte
 nance equipment)\, corroded well casings\, and cross connections in drain
 age spaces. These can make the system more vulnerable to contamination. T
 hough nitrate is often present\, the maximum contaminant level is rarely 
 exceeded. As of July\, no assessed systems tested positive for total coli
 form. Numbers will be finalized in August upon completion of work. These 
 findings highlight water quality considerations relevant to TN water syst
 ems that can pose public health risks\, including infantile methemoglobin
 emia from high nitrate exposure and sickness from total coliform/e coli e
 xposure. Improved compliance can help increase confidence in drinking wat
 er quality and strengthen collaborative relationships between regulatory 
 agencies and businesses. Proactive maintenance protocols and proper educa
 tion can reduce contamination risks\, while fostering cooperative rather 
 than punitive regulatory approaches that facilitate effective and trustwo
 rthy partnerships.\n\nSpeaker:\nKei Kohmoto\n\nAdmission:\nRegistrationFe
