ADOPT-AN-OUTFALL
TIPS AND SUGGESTIONS
The
following are tips and suggestions to keep in mind when testing your
water sample:
- If possible, take the temperature of the
water at the source rather than in the container.
- When collecting water samples, tape a broomstick
to the water sample container to avoid getting yourself wet.
- Prepare the Dissolved Oxygen sample for
testing at the site to avoid trapping air bubbles on the journey home.
You may test for Dissolved Oxygen at home.
- If testing for Turbidity at home, be sure
to mix the water sample since sediments or particles may have settled.
- If the Dissolved Oxygen levels readings
are at 10 ppm, record 10+ ppm on your data sheet.
Observation
Instructions
Temperature
Lower the thermometer 10 cm below the water
surface and keep it submerged for 2 minutes. Read the temperature
while the thermometer is still in the water. Look up the temperature
reading on the chart entitled “Optimal Stream Life at Various Temperatures”
in the manual.
pH
Rip off about a 5 cm strip of pH paper.
Dip the paper in the water and then match the colour to the chart
on the roll. Repeat the test to check for reliability.
Look up the pH reading on the chart entitled “pH Scale” in the manual.
Smelling
Never smell the water sample directly.
Use the wafting technique. Hold your nose about 15-20 cm away
from the mouth of the container. Use your hand to waft the odour
towards your nose. If you detect a smell, look up the smell
on the Water “SENSE” Wheel and Interpreting Your Results, or in the
chart below.
Seeing
Examine the water sample from all angles
if it is possible (top, side, bottom). If you detect something
odd, look it up on the Water “SENSE” Wheel and Interpreting Your Results,
or in the chart below.
If you have questions regarding monitoring
an outfall and water quality testing, please
email (see below) the education coordinator.
We welcome your input! We would
love to post tips and tricks you have discovered along the way.

Contaminants can
go undetected by our senses. For example, micro-organisms from animal
wastes leave no sensory clues. Always be careful and protect yourself
from the water. Wear gloves and wash your hands after testing!
