Currently, expanding uses for urban surface water such as undesignated swimming, intensified recreation, and other unregulated uses require a high microbial water quality, which is not currently covered in existing regulation. Contact with microbiologically contaminated water can result in many severe illnesses like gastroenteritis; fever; skin, ear, and eye complaints and respiratory disease. This project aims at developing effective monitoring and mitigation techniques to keep safely multifunctional urban surface water use. Through comprehensive screening of current microbiological water quality, influence of environmental parameters and mechanistic study important pathogens, nature-based technologies will be developed to remove pathogens pollution.
