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.
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 2 plastic cups as follows; label one cup Alkalinity LLS and the other cup Local Community Treated Water. 3. Pour the 50 mL of Alkalinity LLS into the cup labeled Alkalinity LLS.
In your city, the drinking water was being inspected. After thorough inspection of your city’s water supply, there was data collected on many different aspects of your water supply. As the health and safety inspector it is your job to look through this data and find anything that may be hazardous to the public.
To determine if the water sample meets Canadian Drinking Water Guidelines for Colour. Testing will be done on Local community treated water. The Canadian Drinking Water Guidelines has an aesthetic objective of 15 TCU (True Colour Units) for drinking water; you will test and compare your result to see if it meets these guidelines.
