Changes in pH, hardness and alkalinity can all indicate a change in chemistry that may have resulted from a spill, sewage or increased algal blooms.
Benefits of test strips
Testing is fast easy and convenient it is said they deliver greater accuracy then liquid test kits
Reduces the chance of human error of associated with other tests.
No measuring samples or counting number of drops.
Require less technique
Ensure proper handling and storage
Store in a cool dry place
pH is a measure of the acidity or alkalinity of water. It is usually measured by using a colorimetric test – test strip changes colour with increased acidity or alkalinity. pH varies naturally within streams as a result of photosynthesis. There are a number of reasons that water may have extreme pH values:
The pH scale ranges from 0 to 14:
A ph range of 6.5 – 8 is optimal for freshwater.
A range of 8 – 9 is optimal for estuarine and sea water.
Acidic 0 to 6.9
Alkaline 7.1 to 14
