| Sample Date | [i] Entero CountEntero CountEnterococcus (“Entero”) is a fecal indicating bacterium that lives in the intestines of humans and other warm-blooded animals. It is the EPA preferred indicator for sewage contamination. | Quality | [i] Temp (f)TemperatureHudson River water temperature changes seasonally. Surface water temperature can change on small scales in the river reflecting natural and human influences. | [i] SalinitySalinityEstuaries like the Hudson are where freshwaters in rivers meet the sea. Salinity tells us about the relative contribution of fresh and salt water within a particular region of the estuary. | [i] ChlorophyllChlorophyllA measure of the amount of microscopic algae present in the water. High chlorophyll counts can mean high levels of the nutrients phosphorus and nitrogen, and the threat, or presence, of algae blooms. | [i] TurbidityTurbidityTurbidity is a measure of the amount of fine particles suspended in the water. As turbidity rises, light penetration, a key factor for aquatic plants and algae, diminishes. | [i] OxygenOxygenOxygen concentrations in the water are closely connected to biological activities. Surface waters are typically in equilibrium with the atmosphere such that the oxygen concentration near the surface is close to fully saturated (100%). |

Enterococcus is an EPA-approved fecal contamination indicator.
Samples taken by Riverkeeper, Lamont-Doherty Earth Observatory and CUNY Queens College staff, and processed on the Riverkeeper vessel, according to the 2014 Quality Assurance Project Plan.
Rainfall data comes from wunderground.com. Wet weather is a common trigger of fecal contamination.
Water Quality scoring is based on the 2012 Recreational Water Quality Criteria from the US Environmental Protection Agency (EPA) for safe swimming. Learn More
