pH |
pH in the simplest terms is a scale that
tells whether water |
|
|

 |
is acidic or basic. The
scale goes from 0 to 14, where 7 is |
|
|
|
|
considered neutral anything below
7 is considered acidic anything above 7 |
|
|
Parrish Waters and His Micro Friends |

is considered
alkaline, or basic. Most rivers fall into the 5-8 range. |

This is the
pH testing cube. The cube has different |
|
|
|
|
colors,
that represent different levels of pH. After you mix in |
|
|
|
|
the
chemical provided in the kit, the sample will turn a color |
|
| |
|
and you then
have to match the color to one of the colors on the |
|

cube. |

Dissolved
Oxygen |
Dissolved Oxygen, or DO2 is
basically the measure of |
|
| |
|
dissolved oxygen in water. Oxygen
get into water by aeration |
|
| |
|
like a fast moving current or a
waterfall, it can also get in as |
|
| |
 |
a waste product of
photosynthesis.
|
|
| |
|
|
|
|
| |
|
This is the
Dissolved Oxygen test equipment. |
|
|
|
|
This test is very time
consuming and tedious, it is real easy |
|
| |
|
to mess up, in that case you
would have to start over. |

Nitrate |
Nitrate or NO3, a
water soluble molecule, is formed |
| |
|
after nitrogen from
ammonia mixes with oxygenated water |
| |

|
| |
|
This is the
Nitrate test. This test was also time consuming and |
|
| |
|
at times
confusing, but after many trials we finally figured it out |
|
| |
|
and it was successful. |

Phosphate |
Phosphate comes from the phosphorus
found in soil |
|
| |
|
minerals and rocks. As rocks and
minerals begin to |
|
| |
|
erode, and break down, ions are
released, and it is dissolved into the water. |

test. |

Hardness |
Hard water requires more
soap and synthetic detergents |
|
| |
|
for home laundry and
washing, and contributes to scaling |
|
| |
|
in boilers and
industrial equipment. Hardness is caused by compounds of |
| |
|
calcium and
magnesium, and by a variety of other metals. |

|
| |
|
|
|
| |
 |
This is the hardness
test. This test was rather simple, all you had to |
|
| |
|
do was dip hardness
strip into the water and match the color with a |
|
| |
|
number on the side of
the bottle. |
