Water Monitoring


What why

What/Why?

  • Water testing

    • Identifying water content

    • Allows scientists to have a full understanding of what is affecting their stream or river.


Water monitoring

How?

  • Physical Tests

  • Chemical Tests


1 ph level

1: pH Level:

  • The pH level tells us how acidic or basic our water.

  • The pH range is 0 to 14 with 7 being neutral.

  • While a range of 6.5 to 8.2 is optimal for most organisms


How to t est the ph

How to test the pH

Fill the test tube to the 10ml line.

Add one pH tablet.

Cap the tube and mix to dissolve tablet.

Compare the color of the sample to the pH color chart.

Record result as pH.

pH 4 1 poor

pH 5 1 poor

pH 6 3 good

pH 7 4 excellent

pH 8 3 good

pH 9 1 poor

pH 10 1 poor

pH 11 1 poor


Water monitoring

2. Temperature

  • How hot or cold the water is

  • Colder water can hold more dissolved oxygen than warmer water.


Water monitoring

How to take the Temperature

Place the thermometer 4 inches below the surface of the water for 1 minute. (in a river)

Remove the thermometer and record the results in degrees Celsius.


3 dissolved oxygen

3: Dissolved Oxygen

  • The oxygen amount in the water.

  • Used by fish and other organisms to breathe

  • Fast moving water has more dissolved oxygen than slow, stagnant water


Water monitoring

How to test the Dissolved Oxygen

Fill the test tube to the top of the tube with sample water.

Add two Dissolved Oxygen tablets to the test tube.

Cap the tube. Make sure no air bubbles are in the sample.

Invert until the tablets dissolve (4 minutes)

Wait 5 minutes

Compare the color of the sample to the Dissolved Oxygen chart.

Record result in units ppm (parts per million).

30 C 0 53 106

Dissolved Oxygen % saturation score

91-110% 4 excellent, 71-90% 3 good, 51-70% 2 fair, <50% 1 poor


4 turbidity

4: Turbidity

  • Turbidity is the measure of how clear the water is.

  • Caused by suspendedsediments such as clay, silt, organic and inorganic matter.

  • (Turbidity should not be confused with color since darkly colored water can still be clear and not turbid).

Tributary of Goose Creek, May 13, 2008


Water monitoring

How to test the Turbidity of the water

Fill the turbidity tube to the line.

Place the base of the tube on the outline on the Turbidity Chart.

Look down through the sample water at the Secchi disk icon under the tube.

Compare the appearance of the Secchi disk icon under the tube to the gray Secchi disk on either side of the tube to determine the turbidity.

Record the units in JTU (Jackson Turbidity Units)

JTU Score

0 4 excellent

0 to 40 3 good

40 to 100 2 fair

>100 1 poor

5 phosphates

5: Phosphates

  • Phosphorus is a nutrient that acts as a fertilizer for marine plants.

  • Over half of the phosphates in lakes, streams, and rivers comes from detergents.


Water monitoring

How to test for Phosphates

Fill the test tube to the 5ml line.

Add one Phosphorus tablet.

Cap the tube and mix until the tablet has disintegrated.

Wait 5 minutes.

Compare the color of the sample to the Phosphate color chart.

Record result in Phosphate ppm.

Phosphate ppm Score

4 excellent

3 good

4 2 fair


6 coliform bacteria feces

6: Coliform Bacteria (Feces!)

  • Fecal Coliform Bacteria is naturally present in the human digestive tract but is rare in unpolluted waters.

  • Its presence in water serves as an indication of sewagecontamination.


Water monitoring

How to test for Coliform Bacteria

Fill the tube to the 10 ml line.

Replace the cap.

Stand the tube upright, with tablet flat on the bottom of the tube.

Incubate the tube upright at room temperature for 48 hours. Store out of direct sunlight.

Compare the contents of the tube to the Coliform Bacteria Color Chart.

Test Results Score

Negative 3 good

Positive 1 poor


7 nitrogen content

7: Nitrogen Content

  • Nitrogen is a nutrient that acts as a fertilizer for aquatic plants.

  • Nitrogen enters the water from human and animal waste, decomposing organic matter, and lawn and crop fertilizer run-off.


Water monitoring

How to test the Nitrogen content

Fill the test tube to the 5 ml line.

Add one #1 nitrate tablet.

Cap the tube and mix until the tablet has disintegrated.

Add one #2 nitrate tablet.

Cap the tube and mix until the tablet has disintegrated.

Wait 5 minutes.

Compare the color of sample to the Nitrate Color Chart.

Record the result as ppm Nitrate (parts per million)

If reaction is yellow record 0 ppm.

Nitrate (ppm) Score

2 fair

1 poor

40 1 poor


Invertebrates

Invertebrates

  • Invertebrates (animals without backbones) are a natural and important part of any natural water body.

  • By identifying which species are found, we can accurately determine the overall health of a stream or river.
