Data from: Risk of Gastroenteritis from Swimming at a Wastewater-Impacted Tropical Beach Varies across Localized Scales

This dataset contains measurements of concentrations of MST marker HF183 and fecal indicator microorganisms (fecal coliforms and enterococci). Water samples were collected just outside the river plume in three rivers that impact a Costa Rican beach during the rainy and dry season. Microorganisms were filtered from a 500-mL grab sample onto a 0.45-µm, mixed cellulose ester. Enterococci and fecal coliforms were cultured.HF183 was quantified from nucleic acid using quantitative PCR. We examined microbiological water quality in three rivers that impact a Costa Rican beach.
