Abstract
The goal of this project is to investigate the hydrochemistry of the prairie stream system at Glacier Creek Preserve, namely to determine the chemical behavior as it varies over time. Past sampling revealed annual/seasonal trends, which prompted this study investigating possible changes over the course of a day. To accomplish this, water samples were taken hourly for a twelve hour period in September and November 2018, and were analyzed at the Durham Science Center. All samples were obtained at the furthest downstream site available. The main focus was to study alkalinity and dissolved mineral content. Preliminary data suggests that alkalinity gradually decreases over the course of a day, regardless of the season. Ion concentrations were found to follow diurnal cyclic behaviors during the summer months, with the trends disappearing in winter.
