bull People and pets should avoid contact with foam
bull Wash skinfur that has come into contact with suspected PFAS-containing foam with soap and water
bull Surface water concentrations of PFAS are much lower indicating water is safe for recreation
bull Additional data will be collected
bull MDH will conduct additional recreational risk assessment to verify these conclusions
