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.
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.
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.
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.
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)
