Water Monitoring Testing

What is a pH Level?

pH (Acidity) is a measurement of the acidic, or basic, quality of water. The pH scale ranges from a value of 0 (very acidic) to 14 (very basic), with 7 being neutral. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically. Natural waters with conditions favorable for supporting life usually have a pH reading between 6.5 and 8.5.

pH Level Test

What You'll Need:

  • Large test tube.
  • Sample container with your collected water sample.
  • Protective gloves.
  • Color chart from your test kit.

pH Level Test Procedure:

  1. Fill the larger test tube from your kit to the 10 mL line (upper line) with your water sample.
  2. Take one pH Wide Range TesTab from the foil pack that says "pH" and add it to the test tube.
  3. Cap the tube and mix by turning the tube over and over until the tablet disintegrates. Bits of material may remain in the sample. But, that's OK.
  4. Compare the color of the sample to the pH color chart from your test kit. Record the result as pH on your field data sheet.

Most natural bodies of water have a pH level of 6.5 pH to 8.2 pH. But, if you live near a body of water affected by industrial waste, agricultural runoff, or drainage from improperly run mining operations, your results may differ quite a bit.

This full-featured set of instructions took an extremely technical and difficult-to-understand set of instructions and broke them down into layman terms that school teachers were able to understand. As a result two foreign schools in Uzbekistan and Warsaw, Poland were able to participate in the World Water Monitoring Day event. These instructions also served as the replacement for the on-site training that some of the local teachers missed.

If you need help writing or editing instruction content, contact me today. I'm also really good at testing the accuracy of procedures. I will actually go through the process of whatever the instructions cover and ask questions if I come across something unclear or inaccurate. Then, I rewrite what's unclear or inaccurate. I also include applicable computer screen shots for software instructions and other illustrations to help the user better understand the task they are performing.
