The aim of the present study was to investigate the effect of treated wastewater, untreated wastewater, and municipal water on the quality and quantity characteristics of the bell pepper Urfa Isot (Capsicum annuum cv. Urfa Isoto) and the Capia red pepper (C. annuum L. cv. Capia). We also investigated whether various irrigation waters affect the amount of heavy metal residues. When the results of the analyses were examined for morphological, chemical, and leaf characteristics, the untreated and treated wastewater applications were found to be superior for all parameters compared to that from municipal waters. Between the two wastewaters. the untreated wastewater yielded better results than the treated wastewater. According to the results of heavy metal analyses, no residue was found in the peppers studied, which are classified as the plants from which the fruits are consumed. A hazard index value was determined to be <1. In this case, it was revealed that consumption of the peppers irrigated with the treated wastewater used in our study had no negative effects on the health of the consumer.
