Abstract

Introduction: Potable water is one of the most basic logistics requirements of Armed Forces, in camps, on official as well as personal moves. It directly affects the health of the soldier as well as the combat readiness of committed forces. This study was under taken to assess the effectiveness of major water sterilization formulations available currently and make recommendations regarding usage in the armed forces.
Materials and Method: A comparative study was conducted to assess the effectiveness as well as acceptability for use of four water sterilizing formulations: OFWS; Halazone; NaDcc; and Iodine which can be used for purification of water at individual level. Eight regiments in a forward location were selected by random procedure and all personnel proceeding on leave during a three month period formed part of the study. These eight units were then randomized into four groups.
Results: NaDcc was most acceptable followed by Halazone and OFWS with Iodine being least acceptable. Iodine users –mentioned inability to understand usage, unacceptable taste and odour, complicated usage, longer duration to act. Halazone and OFWS users mentioned that these were complicated to use and took a longer duration for the formulation to take effect. Halazone was found to have the least acceptable taste followed by OFWS. There was no statistical difference between the protective effectiveness of the formulations as per tests conducted in lab.
Conclusion: NaDcc was the most acceptable formulation and its benefits were demonstrated to far outweigh that of older formulations like OFWS, it should be immediately introduced in the Armed Forces.
