Operation Water Drop Taking It Further Problem-Based Learning Lesson

1. The first thing you are going to want to do with your Operation Water Drop kit is to use it. Test the water samples you have been given and your local drinking water (as well as three other water samples such as urban, rural and raw water, in the case of High School Operation Water Drop kits) with the kit’s contents. Record these test results.

To allow students to run tests on five different sources of water. Students are expected to collect three samples of water: Urban and Rural (includes Aboriginal and non-Aboriginal communities) treated waters, and a Raw Source Water.

Tips and advice regarding how to use the High School Operation Water Drop kit in your classroom. There are two methods to go about it - in one method different groups of students test for different components in all of the water samples, in the other method each group of students tests for all of the different components in one water sample.

What is Safe Drinking Water? (High School)

What is Safe Drinking Water? (High School)

Groundwater - found below the ground where it accumulates in between soil and rocks. The volume of water can range from small to very large similar to above ground creeks, rivers and lakes, found in bodies of water that resemble underground lakes called aquifers.

Students enter their test results for the five water samples. Students enter their results for alkalinity, ammonia, arsenic, colour analysis, copper, iron, manganese, nitrate, pH, sulphate, total chlorine and total hardness.

Alkalinity Analysis for High School Operation Water Drop

Alkalinity Analysis for High School Operation Water Drop

There is no Canadian Drinking Water Guideline for Alkalinity in drinking water, but it is an important characteristic of the water and if your local community water is less than the LLS then the water may be quite corrosive, which may result in increased levels of copper and lead leached out from household plumbing.

1.  Cover the area that you are working on with paper and use gloves as the Methyl Purple Indicator that you will be using may stain. 2. Label the 5 plastic cups as follows:  #1 Alkalinity LLS, #2 Urban Treated Water, #3 Rural Treated Water, #4 Untreated Raw Water, #5 Local Community Treated Water. 

Arsenic Analysis for High School Operation Water Drop

Arsenic Analysis for High School Operation Water Drop

Please Note: If high levels of hydrogen sulphide are present in the water sample (as is the case with some raw water samples) please expose the water sample to air for eight hours before doing the arsenic test in order to prevent an arsenic test "eruption" in your classroom!

Colour Analysis for High School Operation Water Drop

Colour Analysis for High School Operation Water Drop

The Canadian Drinking Water Guidelines has an aesthetic objective of 15 TCU (True Colour Units) for drinking water; you will see and compare the different water sources. The 15 TCU (True Colour Units) is the concentration of the Canadian Guideline sample.

Copper Analysis for High School Operation Water Drop

Copper Analysis for High School Operation Water Drop

Copper is naturally present in the environment, but the levels of contamination can be increased around agricultural land (manure spreading), near smelting facilities, and phosphate fertilizer plants, there is also significant amounts of copper released from wastewater treatment plants. The copper piping in most buildings that we consume water from also can contribute to our intake, depending on the corrosiveness of the water. 

Heterotrophic Plate Count Analysis for High School Operation Water Drop

Heterotrophic Plate Count Analysis for High School Operation Water Drop

Currently, the Canadian guidelines recommend that HPC levels should not exceed 500 CFU/ml. Although there are no laws enforcing this recommendation, if this level is exceeded in municipal drinking water, an inspection is often conducted to determine the cause of the increase.

1.  Label the 5 Agar Plates:  Control, and the names of the four water samples to be tested. (ie. Urban Treated, Rural Treated, Untreated Raw, Local Treated) 2. Label the 5 sterile pipettes:  Control (CW), and the appropriate water sample names (ie. Urban Treated, Rural Treated, Untreated Raw, Local Treated)
