Patterson, C., G. Ramirez-Toro, C. Maldonado, AND R. Sinha. Non-PRASA Drinking Water Research on UV Disinfection in Puerto Rico. Presented at 11th CECIA IAUPR Symposium on Potable Water Issues, Bayamon, PR, February 12 - 14, 2015.

Impact/Purpose:

Over 200 public water systems in Puerto Rico are outside of Puerto Rico Aqueduct and Sewer Authority (PRASA) control with 147 of these systems serving between 100 and 500 people. Many of these Non-PRASA systems use source waters that are contaminated by human and animal wastes resulting in a higher potential for epidemic outbreaks of enteric diseases.

Description:

The U.S. EPA and InterAmerican University of San German worked with water treatment operators from Patillas, Puerto Rico on the installation, training and testing of pretreatment/UV disinfection systems in the communities of La Sofia and Apeadero. This presentation provides pathogen removal results and compares operation and maintenance costs associated with water delivery, pretreatment and disinfection systems designed for both surface and ground water supplies. These studies not only benefit small rural Puerto Rican communities, but also develop a concept or approach that can be implemented in other communities in tropical regions.
