A Simple Do-It-Yourself Home Water Color Test

Filtering and purifying water for human consumption means you are inhibiting physical and live elements from passing into and through your body when drinking water. Pure water should be clean and clear of any color. Filter or become the filter is true. Here's a simple way for you to see for yourself at zero cost, the level of color in your water.

- What you will need -

2 x Empty and clean white styrofoam cups.

1 x Bottle of store purchased spring or filtered water. Small bottle.

Find a convenient location to place the styrofoam cups. Try, as much as possible, to set the indoor lighting conditions to always be the same when you conduct the visual inspections. Daytime is preferred.

You can print out this page and use it to enter your findings.

Sampling will be at the kitchen faucet. First take off the spigot screen so as not to create any undue air mixing and then proceed as follows.

1) Run the cold water for at least 3 minutes at full flow then lower the flow.

2) Mark one cup with a "T" and fill it with the water from the tap.

Water sample draw date: __________________________mm/dd/yy.

Water sample draw time: __________________________hr/mm. AM___ PM ___

3) Now fill the other cup with water from your purchased bottled water. Fill to the same level as the first cup.

- Visual color inspection -

4) Now place the cups side by side and look at them from the top straight down.

Does the tap water have a color: Yes ___ No ___

If yes what color: _____________________________

If yes how dark is the color on a scale from 1 to 10: _____

- Long term inspection -

5) Now cover the cups and let them sit on the counter for the next few days. If there are metal ions, these will turn red, manganese ions will turn black, hyrdogen sulphide will turn black, and so on. You can have an endless mix of colors. Sometimes it could take up to 7 days for all changes to take effect with major changes occuring within the first hours to 3 days. During this time, you can occasionally visually inspect the samples and note the date, time and changes you see by repeating step 4. If you have a digital camera, you can take pictures of the changes as required.

You can do this water test on any water source that you frequently use, either at home, the cottage or at work. Although the results cannot be quantified in terms of parts per million (ppm) or milligrams per litre (mg/l), this home test will enable you to better understand the effects of your water over time. You can also do a second test as above but on filtered or purified water to see the difference between your regular tap water.
