The provision of safe drinking water has been one of humanity's most successful public health interventions and is a defining aspect of a devel+oped country. However, ignorance of the potential risks, inappropriate training of staff and managers working on drinking water systems still results in unnecessary waterborne disease outbreaks in affluent communities. Microorganisms present in drinking water sources such as bacteria have been targeted with the aim of limiting their growth as well as eliminating them. A chemical contains a mixture of chitosan, polyvinyl alcohol, nanomagnetic iron oxide, as well as nanocarbon were used. This chemical obtained in the form of nanofibers by the electric spinning process, where the properties of this substance and its shape studied using the scanning electronic microscope (SEM) as well as the transmission electronic microscope (TEM), the type and shape of bacteria. This paper aims to show the bacteria effects on the public health, clearfy their shape and type, as well as stopping and eliminating the bacterial growth
