After spending two weeks testing the water, we discovered a lot of new things and definitely learned a great deal about the East River. Doing this was really fun, we enjoyed the trips to the East River (at least most of us did), the new people we met and all the new things that we learned. Most of us thought that the water quality of the East River would be poor and that few organisms would be able to survive in this body of water. We were surprised that so many organisms live in the East River and that the results indicate a fair water quality besides the positive tests for coliform bacteria. We concluded that while the East River isnt terrible, there still needs to be more testing and protection of this area. Everyone thinks that wastewater should not be allowed to flow directly into the river. Here is a sampling of what the class had to say about what we learned.

I expected the water to be blue not green and I concluded that the reason why the water is green is because there is a lot of algae in the water.

I learned that the East River is not a river and I also learned that there are so many items you can test the water with.

I learned that there is oxygen in the water I always knew that organisms in the water had to breathe, but I did not know how. Doing the research for dissolved oxygen helped to explain to me how that happened, also that the cooler the water is the more oxygen and the warmer the water the less the oxygen. Our results prove this because on the last day, the water was the coldest it was in the two weeks and it had the most oxygen in it. In the chart (11/5), we could see that we have a temperature of 14.9 C (coldest in 2 weeks) and the DO of 6 (highest in 2 weeks).

The dissolved oxygen level (usually around 4ppm) was higher than the BOD level (around 1ppm), this shows that there is bacteria in the water. The more bacteria there is in the water, the lower the DO levels will be. This is because bacteria take in dissolved oxygen to carry on their life processes. The bacteria was taking all the oxygen from the organisms living in the water. This can affect the ecosystem negatively.

I didnt think that it would be a lot of salt in the water. I didnt know that the ocean brings in water to the East River.

My results for salinity on the last day were not what I expected to be because the rain had affected the water. I thought that I would have had a greater effect on the salinity meaning that rain would decrease the salinity of the East River greatly. However, the salinity remained around the same number before the last day it was 30 ppt it went down to 28 ppt when it rained I expected it to go down more. The East River normally has a salinity of around 30ppt because it is mostly ocean water which has a salinity of around 35ppt.

The water is mostly neutral between 7 and 8 the whole time, so its not that toxic for living organisms. We expected this pH since ocean water has a pH of around 8 and neutral water has a pH of around 7, this is a mix of freshwater and ocean water.

I expected the water that we tested to have ammonia, because I know that there were living things (organisms) in the water and these organisms especially fishes excrete waste put ammonia into the water. There were low levels of ammonia.

The turbidity was caused by algae, algae is a plant that produces food through photosynthesis so it releases oxygen into the water which I thought would affect the DO readings.

I thought the turbidity was caused by the mixing of salt water and fresh water

What I learned was there are living things in the East River. I didnt think any thing could live there. I thought it was a dirty place but I was wrong, there are living things in the water.

The results indicate poor water quality because it tested positive for coliform bacteria, which means there is human waste in the water.

I reached the conclusion that the water is very polluted and organisms can live in that type of water.

To me, the coliform results showed that the water in the East River is not healthy to do anything with or in. Everyday it was tested, it came out positive for coliform. Coliform comes in from the overflow of waste into the river. Coliform are bacteria found in the intestines and are present in feces. That is nasty and it was found in the water.

We noticed that most of these problems are because we dont take care of our water, now we hope that people take care of their environment a little more and have consideration for the waterways.

P.S. We did the testing in the cold so appreciate the work

o Dissolved Oxygen (A test used to find out water quality)
o Biological Demand Level (The measure of the oxygen used by microorganisms to decompose waste.)
o Stream Flow (The amount of water moving past a specific area in a specific amount of time. This is affected by the Watershed.)


o General Observations (Our observations of Colonial Park, our water testing site.)
o Temperature (Measures how cold the water is, some things can not grow in certain temperatures)
o PH (Measures the Basic and Acidic levels of the water)
o Nitrates (Measures nitrates, which are essential for plant and animal growth)

o Macroinvertabrates (Small animals found in the water that can help you determine the quality of the water.)
o Phosphates (How much Phosphate is in the water, which indicates pollution levels)
o Introduction Letter (an introduction about the root river and our school)



Where we were: Colonial Park Racine, Wisconsin

Weather in the past twenty four hours was clear and sunny.

Weather now/then was very overcast.

The water appearance was dark brown with a foamy surface.

There was no water odor even though we sniffed high and low to put it that way.

The temperature for the water was 53.8 Degrees Fahrenheit.


There were no submersed aquatic plants in the Root River.

As for the riparian vegetation there was a lot I will describe it (R meaning right, L meaning left).
R/L Hardwood trees
R/L Bushes and shrubs
R/L Tall grasses ferns etc.
L Lawn
R/L Boulders and rocks
R/L Gravel and sand
L Bare soil

The canopy cover for the Root River was rated as 25%.

The bottom substrate was recorded as boulder, cobble, gravel, and sand.

For the watershed features there was only a golf course and it was marked as a 1 and2; 1 meaning it was present and 2 meaning it has an impact on the stream.

The Root River was never channelized.



It is very important to know the temperature of the water. The animals in the water need a certain temperature to live; some animals need higher or lower temperature to survive.

Colder water has higher dissolved oxygen then warmer water. The temperature changes throughout the day, according to the weather. Also it changes through out the year.

As the temperature gets higher the photosynthesis increases too. That means the plants in the water grow faster and die faster. When they die, the plants go to the bottom and disingrate.

How to test water Temperature:


1. You take the temperature meter out
2. You push mode to turn it on
3. You put the test meter in the water
4. You check it well it is in the water
5. You record it on a piece of paper
6. You shut it off by pressing mode again

I hope you learned a little bit about temperature.



PH measures if the water is too basic or acidic. The lower the Ph the more acidic the water is, and the higher the Ph the more basic the water is. In the U.S.A. the ph of the water usually between 6.5 and 8.5. If the Ph is below 5 or above 9.5 plants and animals can not live in that water.

Motor vehicles have nitrogen and sulfur oxides and they can go into the environment. When these things combine with water vapor in the atmosphere, they form acids. The acids evaporate in the clouds and when it rains or snows the acids fall to earth. The acids can damage trees, crops, and buildings and if the acid gets in rivers or lakes it can make it very acidic. If the water is too acidic, the plants and the animals that live in the water could die.
HOW TO DO THE TEST
1. You can use a ph meter
2. And then you open the Ph meter that you are using
3. And then you put it in the water and press mode to turn it on
4. Then you take it out of the water when the numbers stop moving
5. And finally you record what it says
And thats how you do the Ph.

Stream flow, or discharge, is the volume of water moving past a cross-section of a stream over a set period of time. It is usually measured in cubic ft. per seconds (cfs). Steam flow is affected by the amount of water within a water shed, increasing with rainstorms or snow melt, and decreasing during dry periods.

Our findings: Site 1: We measured twice at the first the river was 45 ft. wide the average depth 5.999 10th ft. The Stream flow was 20.27cubic ft. per second. The second time was 37 ft. wide average depth was 0.6765 10th ft. Stream flow was 27.217367 cubic ft. per second.

Site 2: The steam with was 54 ft 9 in. The average depth was 5.8910th ft. The Stream flow is 169.6 cubic ft. per second. The second time was the stream width was 50ft. The average depth was .686510th. Stream flow was 182.70126 cubic ft. second.
Site 3: The length is 20 ft. the width is 37 ft. the average is 0.6765 ft. the steam flow is 27.21367 cubic ft.per second.

Dissolved oxygen test are important because it tells us how much oxygen is dissolved, which tells us what kind of animals live in the water and what kind of water quality there is. Oxygen can enter the water in many ways. Other things can affect D.O. (Dissolved oxygen) levels like decaying plant of animals, because decaying bacteria needs oxygen to break down the matter, so they take that oxygen from the water. So you will get different D.O. results in different types of the day because water is colder in the morning and warmer in the afternoon. It will also change in seasons depth of water. D.O. levels are normally measured 2 ways, ppm which is parts per million, or percent saturation, which takes the maximum amount of oxygen in the water, then measured how much oxygen is in the water, then they are compared. Over all, dissolved oxygen is very important and very interesting.

1. Take out the dissolved oxygen (DO) test kit. Follow the instructions that are with the kit. Remember to record your results in the ppm (parts per million).
2. When collecting your water sample, here are some important guidelines:
Sample the water away from the bank and BELOW the water surface level.
Be careful not to get any air bubbles in the sample during collection; it may result in a false high reading.
Allow the water to gently fill the DO sample bottle from bottom to top.
Put a lid on the bottle while its UNDER WATER.

3. Test the DO level immediately. Biological activity in the sample and exposure to air can quickly change the DO level.

4. Repeat the DO test THREE times.

WHAT TO EXPECT

0.0-4.0 POOR
Some fish and macro invertebrate
Populations will begin to decline.
4.1- 7.9 FAIR
8.0-12.0 GOOD
12.0+ RETEST
Water maybe artificially aerated.

1. Take 2 samples of water- one is tested right away then we waited.
2. Record the DO level (ppm) of one immediately using the method described in the dissolved oxygen test.
3. Place the second water sample in an incubator in complete darkness at 20*c for 6 days. If you dont have an incubator ,wrap the water sample bottle in aluminum foil or black electrical tape and store in a dark place at room temp(20*c or 68*f).
4. After 6 days take another dissolved oxygen reading (ppm) using the dissolved oxygen test kit.
5. Subtract the day 6 reading from day 1 reading to determine the BOD level. Record your final BOD result in ppm.

What your results mean:
1-2 is very good because there will not be much organic waste present in the water supply.
3-5 Fair: Moderately Clean
6-9: Poor: Somewhat pullulated usually indicates organic matter is presented and bacteria are decomposing this waste.
100or greater: VERY poor: very pullulated contains organic waste.

The Phosphate Test
What is the Phosphate Test for?
A phosphate test is used to find out how much phosphate is in the water. Phosphates can get in the water from soil that has fertilizer in it. Fertilizer has phosphate in it.

How to do the Phosphate Test
To do the phosphate test you will need these items:
1. phosphate test kit
2. bottle with a closable lid
3. data collection student worksheet
Here are the steps to do the phosphate test:
1. Remove the cap from the plastic bottle and fill it with your water sample. Fill it to the 10 ml. mark.
2. Add 1 packet of reagent HI 3833-0.
3. Replace the cap and shake the water and reagent until the reagent disappears.
4. Remove the cap to your plastic bottle and transfer your water to the color comparator cube in you test kit and let it sit for 1 minute
5. After 1 minute is up, determine which color on your cube matches the solution.
6. Record your data.



Nitrates usually come from fertilizers, sewage, and industrial waste. High levels of nitrates are good because it causes plant life and algae to grow. Nitrate is the same thing as nitrogen so animals and plants need nitrogen to build protein. Nitrogen is an element.

1. Fill the glass cuvet to the 10 ml mark.
2. Add 1 packet of reagent HI 3874-0.
3. Replace the cap shake vigorously for exactly 1 minuet. A deposit may remain, but will not effect measurement. Time and the manner of shacking can affect the results.
4. Wait 4 minutes to let the color develop. Remove the cap and fill the color comparator cube with 5 ml of the treated sample.(to the mark)
5. Determine which color matches the solution in the cube and recorded the result as mg\L (ppm) of nitrate-nitrogen.
6. It is better to match the color with a white sheet at about 10 cm behind the comparator.
7. To convert the reading to mg\L of nitrate (NO3), multiply the reading by a factor of 4.43.
Health and Safety
The chemicals contained in this kit may be hazardous if improperly handed. Read Health and Safety Data Sheets before performing the test.

This is a picture of a nitrate test.


Macroinvertebrates
Stream bottom macroinvertebrates cannot move to avoid pollution, a macroinvertebrate sample can be an indicator of water quality. The macroinvertebrates that you find can give you information about water pollution that you wouldnt notice when the sample was collected.

Species of macroinvertebrates that are found in colder waters that need high levels of dissolved oxygen are indicators of a healthy stream. Macroinvertebrates that are found in warm water are indicators of an unhealthy stream.

Testing
There are two types of seining net. The types are the kick seine and the dip net. The kick seine is best for rocky or gravel stream beds. The dip net can be use in many kinds of stream beds. The net should be on the stream
Bed with no water going under the net.

Crossroads

This was a rather enjoyable project. We learned many things at our neighboring schools pond. Our hypothesis stated that our water quality would be good enough for organisms to live in. We did tests of the DVHS pond water to see if the ponds water was able to sustain life. The dissolved oxygen levels being at 5.4, which is average. Our nitrates and phosphate levels were exactly the same, zero. Our water temp was 21 degrees Celsius, and carbon dioxide level was 5.0 (average). This data proved our hypothesis correct. Plus, when we were there we saw many organisms living in the pond. We saw dragonfly nymphs, fish, worms; protozoas like pond scum, algae and diatoms. We also saw water beetle larva and plants like anacharis..

We learned that water needs good oxygen levels in order to support living organisms. We interpreted from our data that the pond is healthy for organisms that are already living in the water and it is of good water quality, but most likely not able to be drank by humans.

In conclusion, our hypothesis: We think our water is good was correct in the sense that it is good for the plants, animals and other living organisms that live there, but in another sense the water is bad for us to drink.

 



Verdigre Public School

I learned a lot about farm pond water. The temperature of the water was about 9 degrees Celsius. The nitrate level test resulted in 1.3 ppm (parts per million) and the pH level test resulted in 7.66. E. Coli forms were clearly present. In order to find out if E. Coli was present, we incubated the water for 48 hours. After the first 24hrs the water was yellowish-brown, which indicates E. Coli. We incubated it another 24 hours for a total of 48 hrs. The water appeared more chalky. We tested it to see if it was fluorescent. Sure enough, it was.

I also learned that even though farm ponds may look disgusting and filthy, some of their qualities aren't that bad. There are a lot of E. Coli in the pond though.

Since there are no fields nearby, there is a low number of nitrates. The pH level is almost neutral because of the few acidic and basic factors that would play a role in changing the pond (to be more acidic or more basic).

Next time, I would like to try taking samples from different areas in the pond (middle, middle edge, very edge, etc.) I would also like to try taking samples from another pond on the same farm and compare the results from that pond with this pond.

Global Water Sampling Project: Final Report
W.H. Cushing Workplace School
Calgary, Alberta


The children at W.H. Cushing Workplace School, from kindergarten to grade 3, really felt like scientists when they gathered and analyzed their water samples. We are very interested in learning about the results that other schools came up with, as well as in sharing our results.

For the most part, the children thought that our water quality would be good, although some were concerned about the quality. In particular, it was the variation in water colour that made some children suspicious of the quality.

Our water testing results support the hypothesis that our river water is of good quality. As a school, we each did a portion of the tests, and below is a summary of each classs reaction to the data that they gathered:

Kindergarten:
On November 3, 2004 we went to the Bow River to do our water testing. Our water was very clear and had no odour that we could observe. We found that the temperature of our water was 1 degree Celsius in the morning and 2 degrees in the afternoon. When we tested our waters pH level, we found that it was 7. This means that our waters pH is just like that comes from our taps. We also tested our water for phosphates; we found that our water had 1 ppm of phosphates. This means that there is not a lot of dishwasher or laundry detergent in our river. The last thing that we tested for was our dissolved oxygen. Dissolved oxygen lets us know how much oxygen is in our river. We found that our river has 2 ppm of DO. Dissolved oxygen levels below 3 ppm are reported to be stressful to most aquatic organisms, so we were a little concerned when we saw this number. Because we noticed many plants and animals growing in and around the river, we concluded that there must have been a mistake made when we gathered our sample and did the testing. Overall, we believe that our river is very clean, and this is great news!

Grades 1/2 Miss Harvey
We did a test for phosphates. We saw the water sample turn light blue. This indicated a low level of phosphates in our Bow River water sample. It took over five minutes to turn light blue.

The phosphate level of our water sample was 1.5 ppm, which is a good level.

Through this water sampling, we learned that some water has phosphates, and some doesnt. We learned that phosphates are in the water when lots of algae and plants grow in the water. We learned that a high phosphate level is not a good sign. When we put the tablet in the test tube and waited for five minutes, we didnt know it would turn a different colour, but it did. We found out that the Bow River water was clean, because it turned light blue. This means good. We wonder if the Bow River sometimes has a high phosphate level. We were very happy to find out that our results were good. It made us glad.


Grades 1/2 Mrs. Lynn
Our water temperature was 5 degrees Celsius (we went in the afternoon on a bright, sunny day J). The nitrate level was 4 ppm. We thought that the nitrate level was at a safe level. Some of us believe that the water is good because the nitrate level is at a natural level. We also still believe that the water is good because plants and fish live in the river. As well, many of us thought the water was cleaner than when we started because we have been picking up garbage and straining leaves out of the water with our families. Some of us still think that the water quality is poor because there are probably germs that we cannot see and because of the animal waste and human garbage. We want to learn more about water filtration. We also want to use our voices and posters to tell people about water. Water is special and valuable.

Grades 2/3 Ms. MacCallum
Our class was very excited to gather water samples with the grade 9 students from the National Sport School. In small groups, we gathered our samples and performed the tests. Across all of the groups there was a slight variation in results, so what we have reported is an average, or the values around which most groups seemed to centre. When doing the Dissolved oxygen test, our results varied from 1 ppm to 4 ppm, with most groups obtaining results of 4 ppm. We were convinced that the low numbers for dissolved oxygen must have been because of errors. We found the nitrate level to be 4 ppm, which is good. Phosphate levels varied between 1 and 2, which ranges from excellent to good. Our initial hypotheses were mixed some of us thought that the River water quality was good and some thought that it was poor. After analyzing the results, we have concluded that the overall water quality of the Bow River varies from good to excellent.

 



Pembroke Hill School

Our hypothesis was that the sewage effluent from the Country Club Plaza residences and businesses would significantly change the water quality of Brush Creek, decreasing the water hardness and pH while increasing the chlorine count and fecal coliform level. We anticipated that the the Plaza would cause significant increase in nitrate, phosphate, and BOD readings.

Was our hypothesis confirmed? Not entirely. We did find that dissolved oxygen and BOD readings increased downstream of the Plaza. We suspect that the high dissolved oxygen reading is at least partly due to the fact that the creek is highly aerated by running over waterfalls and wide, shallow, concrete areas after it leaves the Plaza. Higher BOD levels could be due to increased bacterial contamination from the Plaza, but fecal coliform was so high at all locations that no difference could be detected with our testing kits. Next semester we will use more sophisticated coliform sampling techniques to resolve this issue.

Hardness, chlorine, pH, nitrate, and phosphate readings were essentially the same both upstream and downstream of the Plaza.

Nitrate, phosphate, and chlorine readings were all essentially zero both upstream and downstream of the Plaza, which frankly was surprising considering that residential areas and golf courses were upstream. We expected more fertilizer run-off. Perhaps this was due to the time of year--we may find higher phosphate and nitrate levels in the spring. The low chlorine levels indicate that very little treated water is entering the creek.

The following methods were used for each of the tests:

Nitrate, Phosphate, Hardness, Chlorine, and pH were all tested using Hach Test Cubes.

Dissolved Oxygen and BOD were determined using a LaMotte Dissolved Oxygen Test Kit.

Coliform was measured using a Flinn Scientific Bacterial Pollution Coliform kit.

Location Note #1: The location upstream of the Plaza is in a mixed neighborhood, with high-income residential neighborhoods and a golf course on one side of the creek, and a neighborhood shopping center, including two service stations, on the other. Feeder creeks leading to this location are largely paved, with straight stone or concrete sides, and run through middle-class residential neighborhoods.

Some foaming of the water was detected, as was the presence of small amounts of oil on the surface. By spring, we hope to find or develop a test for hydrocarbons, which would be useful considering that this part of the creek is subjected to service station and parking lot runoff.

Location Note #2: The location downstream of the Plaza consisted of an old urban development project, in which Brush Creek was entirely paved with high concrete or stone sides. As a result, the creek was very wide and very shallow (about 1-2 centimeters deep) at our sampling point. It also was running along an amazing dry stone wall 20-30 feet in height and under a beautiful old stone and steel bridge which, sadly, is scheduled for demolition. This architecture certainly affected the dissolved oxygen level by aerating the water, but made the environment unsuitable for any but the tiniest animals and plants.

We are looking forward to the spring sampling! Thanks for this opportunity.

National Sport School

The grade 9 class at the National Sport School really enjoyed this project. We learned a great deal about water quality, the water quality of the Bow River specifically, and what is required to ensure that we are drinking safe water.

We had the opportunity to watch aquatic biologists at work. They demonstrated benthic macroinvertebrate sampling and electrofishing for us.

Our class realizes how fragile this resource is, as well as how easily it can become contaminated.

The class came up with a variety of hypotheses. Some of us felt the water quality would be great and some of us were felt it would be poor because it passes through our city. We found out that the Bow River meets all of the guidelines with the exception of dissolved oxygen. Our DO levels were low but we think that this is due to an error in sampling.

Thank you for this exciting opportunity!

According to our observation of the water quality in this area, we discovered that there is a relation between diluted oxygen level with various kind of plants and animals living in the water. This was shown from the amount of living plants and animals that live in the water along that river. We didnt purposely measure the diluted oxygen level, but by seeing all those living plants, we could say for certain that the water in the river certains sufficient diluted oxygen as a result of plants photosynthesis.
We measure the pH level, it was 6, it was neutral-a little acidic. This means the water in Cikahuripan Village can be consumed. Besides measuring the pH level, we also measured the water clearness, and we came to conclusion that the more unclear (cloudy, muddy) the water is, then the less diluted oxygen it has. This kind of water categorized as Poor Water Quality. We have also observed the macro organism found on the site and we could say that the water in the river is Fair Water Quality. It can be consumed although it is not the best.
Our observation didnt meet fully our expectation, we did expect that the water river can be categorized as Good Water Quality, because it is a water spring. People of Cikahuripan Village use it both for their daily lives, drinking, cokking, taking a bath and recreational use such as fishing, although it is not enjoyable enough to swim in it.

Bernice A Ray School

This was a terrific experience. We learned a lot about our local watershed and the Connecticut River. Our hypothesis stated that because we live in a rural area, we thought our water quality would be good. We learned through performing water sample tests that our water quality is very good but we have some concerns about the dissolved oxygen levels and the river's ability to support and sustain a healthy living environment for fish and insects. We have such an interest in learning about water quality that we sent out water quality testing strips to volunteers who sent us back data from almost all fifty states and from countries such as Ireland. We even received water samples from the North and South Pole! This project has led us on an amazing journey and allowed us to make connections within the classroom and throughout the globe through investigating our own water supply and analyzing the data from other states and countries. Thank you for sharing your data with us!
