Watchman Field Guides creates practical, easy-to-follow resources for real-world emergencies. Our Water Purification and Treatment Field Guide helps families, travelers, and preparedness-minded individuals find, collect, treat, and safely store water when normal utilities are unavailable.
The guide explains four major water hazards—physical, biological, chemical, and radiological—and shows why clear-looking water is not always safe. Through step-by-step instructions, warning signs, treatment comparisons, checklists, and emergency decision guides, readers learn how to choose the proper treatment method while avoiding dangerous mistakes and cross-contamination.
From rainwater harvesting and well maintenance to hidden household water sources and emergency disinfection, every section is designed to help readers assess the danger, treat the water, and verify that it is safe.
Our mission is simple: provide dependable knowledge that helps people protect themselves and their families when clean water matters most.
