Mill Creek Water Study:
Below are the results I sent to the Mill Creek Restoration Project www.millcreekrestoration.org. Unlike Keehner Park, where we did our fall study, this stream is in excellent condition (according to the data we collected), I will let you know if I hear differently.

Date: Wednesday April 28, 2010
Site: Union Center Blvd
Time: 12:30 PM to 2:30 PM
Air Temperature: 63 degrees
Weather: Sunny no clouds
School: Homeschool Network of Greater Cincinnati
Fecal coliform:
We only have purple colonies (there can be purple, green and blue)
We have 19 purple colonies which indicates excellent
All of the quick coliform tests (from the younger kids kit) turned mt dew color/foamy yellow-green.
MacroInvertabrate Study:
Group A:
Water Penny Larva (a)--found 3
other snails (a)--found 1
Group B:
damselfly nymphs (a)--found 3
dragonfly nymphs (b)--found 11
sowbugs (a)--found 3
Group C:
aquatic worms (a)--found 2
The kids also found a frog and 2 salamanders which I know aren't on the sheet, but I know they are an indicator of water health. We also found tons of snail and salamander eggs.
Water Temperature:
Temperature (group 1): 12-12=0
Temperature (group 2): 14-12=2
Temperature (group 3): 10-10=0
Official average temperature change: less than 1 = excellent
Biochemical Dissolved Oxygen:
Three groups had a result of 0
Two groups had a result of 2
Overall BOD: less than 2 = excellent
PH:
Three groups had a result of 7
Two groups had a result of 8
Overall average is 7.4 = excellent
Total Phosphate:
All 5 groups got a result of 2 = good.... we had a hard time interpreting this result as it looked more yellow than pink....we went with 2, since it wasn't clear.
Turbidity:
All 5 groups got a result of 0 = excellent
Nitrates:
3 groups have 0
2 groups have 2.5
Average would be 1.0 =excellent
Here are the field trip details:
What: Mill Creek Restoration Water Quality Program
Where: Union Center Blvd Creek You park in the parking lot for the RAVE Theater near the second entrance to the shopping center (the sign says theater entrance). The stream is down under Union Center Blvd.
When: Wednesday April 28th 12:30 PM (please eat lunch beforehand)
Who: Homeschoolers ages 6-14
RSVP: Laura
Please come dressed for the weather (rain or shine--the program is held regardless of weather) and wear boots or water shoes as we will be getting into the water to do the macroinvertebrate study, water temperature and to pull water samples.
The water quality study is extremely hands on and includes macroinvertebrate collection, water sampling, and running tests on the water including nitrate levels, water turbidity, phosphate levels,
dissolved oxygen, ph levels, water temperature and fecal coliform bacteria testing. Each child will get to participate in running each of the tests, they will rotate in groups through stations where each
test will be conducted.
Mill Creek in southwest Ohio is one of the most severely polluted and physically degraded streams in the United States. In 1997, because of its multiple stressors and sources of pollution, the national river conservation group American Rivers designated Mill Creek as "the most endangered urban river in North America."
The stream flows 28 miles south from its headwaters in Butler County through the geographic heart of Hamilton County and the City of Cincinnati to its confluence with the Ohio River, just west of the
downtown riverfront. Its watershed covers southeast Butler County and approximately the central third of Hamilton County and encompasses all or parts of 37 political jurisdictions. Within the City of Cincinnati, over forty neighborhoods are located in the Mill Creek drainage basin.
