Abstract

Water quality in stored rainwater changes during storage for various reasons and it is necessary to investigate these variations in order to use it safely. In this paper, an attempt is made to examine the effect of the location of storage reservoirs on rainwater quality. However, the experiment was carried out using groundwater instead of rainwater due to a lack of rainfall during the period of the experiment. Water that was stored in the containers located both indoors and outdoors was analyzed for ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, turbidity, color, coliform bacteria and bacteria periodically for about three months from the beginning of August to the end of October. The results obtained show that variations in water quality were insignificant between the water stored indoors and outdoors, but the appearance of water was quite different.
