Qualitative Introduction to Water Pollution Kit

Scientific Concepts and Processes

• Chemically examine natural waters
• Gain a basic understanding of water analysis
• Interpret tests
• Identify ten common pollutants in natural waters
• Measure pH of water samples

What are some common causes of water pollution in todays world?

• Organic waste from sewage
• Industrial chemicals dumped into ground water
• Rain contaminated by air pollution
• Fertilizers and pesticides washed into water from farmlands

This kit provides an unsophisticated, but effective way to examine their regions natural and treated waters. The easy-to-perform chemical tests in this kit qualitatively identify many common water pollutants.

Pollutants are detected through color changes: the deeper the color, the greater the pollution. Results are safe, reliable and very dramatic. Tests are performed for these common pollutants:

While conducting these tests, students also learn about the different methods used in quality water testing methods, How to interpret results from these methods, and how to identify the pH of locally collected water.

This kit includes enough material to conduct 50 tests for each of the ten major pollutants.
