June 2026 Recently Revised Resources

CI has released new and revised resources! These CI Pamphlets have been updated to reflect the newest editions. Fun fact: CI Pamphlet numbering spans from early foundational documents (e.g., Pamphlet 1: Chlorine Basics) to much newer topics with higher numbers (e.g., Pamphlet 155: Water and Wastewater Operators Chlorine Handbook), reflecting decades of development rather than a strict category structure.
