This investigation was to determine if the type of water used: bottled, tap, or polluted urban river water, would have an impact on Raphanus sativus seed germination and plant growth. Ten samples from each of the three sources of water were used for the investigation. A control group of ten samples was watered using snow melt as this is the most naturally occurring water in our earth system. Raphanus sativus seeds were used for this research due to its very short growing cycle. All supplies were gathered and the same protocols were used for each sample in every type of water used. The water used was tested before application, and the gathered data recorded in logbook. Each result was compared to the model for healthy water provided by the DEQ (Department of Environmental Quality). The following parameters were tested: dissolved oxygen, air/water temperatures, nitrates, phosphates, pH, copper, and turbidity. All manufacturer directions will be strictly followed and results recorded for further study. One Raphanus sativus seed was planted in each peat pot, using the same soil type, and given the same amount of water and sunshine. A calendar log was kept that recorded day of first growth, how many trials germinated in each type, and measurement of plants once they germinated during this investigation. Results were analyzed and showed the data partially supported the hypothesis.
