Abstract— In this paper the spectroscopic measurements of spark discharge in water were investigated. A point-topoint type discharge was generated between a stainless steel hollow needle electrode and a stainless steel rod electrode in a cylindrical reactor made from PTFE. It was found that the emission spectrum generated in surface water is not affected significantly by the presence of chemical and microbiological contaminates. The spark discharge was shown to be a very unstable type of discharge in the sense that every 20 ms spark pulse had a different emission intensity.
