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 consumed carbon dioxide and
produced simple sugars and oxygen which created the oxygen abundant atmosphere
in which more advanced life forms could develop. (Brown, 1994) The mystery of
how Earth's oxygen levels rose is very complex. Scientists don't agree when or
how the oxygen on earth got here, but we know we could not live without it.
(Pendick, 1993) Oxygen is crucial for humans to survive. Dissolved oxygen is
also crucial for most fish and aquatic organisms to survive. Dissolved oxygen
is for them what atmospheric... [continues]
