Determining Water Quality of the Rouge River near Hines Dr. Outer and Dr. Intersection in Dearborn H

Hypotheses for the Water Quality in Rouge River

1. Creating 2 data tables.

2. Write 2 differents hypotheses of 500 words for each, and tell how you arrived at the 2 hypotheses, and then write for each hypothesis whether the data prove or disprove hypotheses.

I will write the professor’s explanation for the two parts for each question.

I will give some information about 3 selected locations in Rogue River.

Each location had 4 packs of leaves each with 10 gms of

1. Oak

2. Maple

3. Aspen

4. Mixed (Oak, Maple, Aspen) in equal proportion to a total of 10 gms.

My dr said “This information is from a previous experiment’s result for colonization. 
It looks kind of similar to what we are expecting. You have to present 2 different results in 2 unique tables or write another 2 forms you think appropriate and present them in a different graph for each to make them visually understandable. You have to expand those results with whatever you noticed at the site and find explanations for all those you noticed at the river and surrounding area.”

*Location 1 (Please include descriptions of sites in your paper)

The leaves were decomposing and had signs of colonization

1. Maple- Caddis fly larvae 10, Midges 6 and Dragonfly larvae 2 Stonefly 1

2. Oak- Caddis fly larvae 11, Midges 2, and Dragonfly larvae 1

3. Aspen - Caddis fly larvae 20, Midges 6 and Dragonfly larvae 2 Stonefly 1

4. Mixed Caddis fly larvae 22, Midges 10, and Dragonfly larvae 2

The leaves were decomposing and had signs of colonization

1. Maple- Caddis fly larvae 11, Midges 2, and Dragonfly larvae 1

2. Aspen- Caddis fly larvae 16, Midges 2, clam 1

3. Oak- - (Missing)

4. Mixed -Caddis fly larvae 28, Midges 2, and Dragonfly larvae 2

Here also decomposition just started so very limited colonization

1. Maple– Caddis fly larvae 11, Midges 6 and Dragonfly larvae 3 Stonefly 2

2. Oak - Midges 2 types=10 (4+6) beetles- 2 , Caddis fly larvae 5, isopod 1

3. Aspen-Midges 10, Caddis fly larvae 2

4 Mixed- Midges 6 and Dragonfly larvae 3

Using the result from the previous information you are going to determine the water quality of the Rouge River in the region near the Hines Dr. Outer and Dr. intersection area in Dearborn Heights.

From the first Rouge River lab, these are the hypotheses that had found.

The water quality of the Rogue River at the Helms Haven Park area is good.

So, for this lab, you are trying to test your hypothesis (given above) with the data provided.

To find which macroinvertebrates indicate good water quality which indicates polluted water you can use the list given below.

Group 1 - pollution sensitive (require higher DO, neutral pH, cold water) E x. mayflies, stoneflies, caddisflies

Group 2 – somewhat pollution tolerant Ex. scuds, dragonflies, damselflies, clams, beetles, isopods.

Group 3 – pollution tolerant (can tolerate low oxygen, lower/higher pH, warmer water) Ex. aquatic worms, midge larva.

With the data I gave from a previous study you are going to create 2 different tables:

With four columns with the titles:

?Highly sensitive

?Somewhat tolerant

?Pollution tolerant

?Do not know

List all the organisms from the previous study to the appropriate columns.

Then you count the number of macroinvertebrates from each site and determine the 2 hypotheses are supported or not  supported. You can add all the individuals from each type from each site and record a total number for each table.

Then you write unique 500 words for each hypothesis, (Use the map Rouge River Spring Macroinvertebrate Monitoring) and tell how you arrived at the 2 hypotheses and is the 2 hypotheses are supported by the data or not.
