NOTES:
- PARTICULATE MATTER: TYPE I water should be contain less than 500
particles per liter that are greater than 0.20 micron in size.
- Other parameters such as particle size, heavy metal content, and/or
trace elements and carbon dioxide should be considered and monitored
when appropriate for special or specific uses.
- Organisc and other contaminants may be reduced with the use of
activated carbon.
- Any method of preparation of the three types of water is acceptable
