Over two-thirds of the population of Puerto Rico was at potential risk of exposure to bacterial contamination in the aftermath of Hurricane Maria, according to government test results obtained by NRDC. More than 2.3 million Puerto Rican residents were served by water systems which drew at least one sample testing positive for total coliforms or E. coli after Maria devastated the island in September.
Bacterial testing was recently conducted by the Puerto Rico Department of Health in response to the hurricanes, according to the Environmental Protection Agency. NRDC obtained the results for coliform bacteria and E. coli from government sources, but has not received test results for other contaminants.
