Follow along with Peter Thomson, senior director at CAWST as he conducts the Horrcks' test to calculate the correct chlorine dosage for a batch of drinking water.
This module also includes practice scenarios and an opportunity to explore some frequently asked questions that technicians ask when using the modified Horrocks' Method.
This project is made possible by the generous support of the American people through the United States Agency for International Development (USAID).
