Faster Dissolved Oxygen Test Kit
Purpose The purpose of my project is to determine if there is any significant difference in dissolved oxygen (DO) levels as measured by the traditional HACH® method or the newly developed CHEMets® test kit under typical field conditions. Hypothesis My hypothesis is that there is no significant difference in dissolved oxygen (DO) levels as measured by the traditional HACH® method or the newly developed CHEMets® test kit under typical field conditions. Review of Literature "Ours is a watery world, and we, its dominant species, are walking sacks of sea water. The presence of large amounts of liquid water on Earth make our planet unique in the solar system." (Hill, 1992 p. 477) People have recently become more concerned with preserving our earth for future generations. Even the government pitches in to help save our earth by enacting laws to help preserve our natural resources. There is local evidence that improved sewage treatment means improvement in water quality. Monitoring on a national level showed that large investments in point-source pollution control have yielded no statistically significant pattern of improvement in dissolved oxygen levels in water in the last 15 years. It may be that we are only keeping up with the amount of pollution we are producing. (Knopman, 1993) The early biosphere was not pleasant for life because the atmosphere had low levels of oxygen. Photosynthetic bacteria con...
