Write introduction for this experiment (Measurements of Water Quality and
the Use of Portable Meters in Environmental Analysis)about types of water and answer all these
questions any information use. writes the reference
1. What factors give rise to hard water being slightly alkaline and “natural” river water being slightly acidic? 
2. What is considered an acceptable pH range for drinking water? Why are there health concerns about drinking water being acidic? 
3. Describe the relationship between the conductivity and the Total Dissolved Solids (TDS) for a water sample. 
4. Explain whether a conductivity measurement can give useful information about the individual type of ions present or the nature of organic pollutants present in
a sample of a healthy environmental water body.
