2014 Hudson Data Jam Competition

Making data "sing" through creative expression

 

The Hudson Data Jam Competition challenges students to creatively tell stories for a general audience using data from the Hudson River watershed.

Fecal Indicator Bacteria & Rainfall (Riverkeeper)

Fecal Indicator Bacteria & Rainfall (Riverkeeper)

 

These data show the fecal indicator bacteria (Enterococci) and rainfall amounts at five sites along the Hudson River. The data shown represent single samples. The data were collected by G. D. O’Mullan, A. R. Juhl, and J. Lipscomb for Riverkeeper.

According to Riverkeeper's Hudson River Testing Sites webpage, Enterococcus is an EPA-approved indicator of fecal contamination in water. Water quality can be determined by looking at Enterococcus counts in cells per 100mL of water. Acceptable water quality is between 0-60 cells/100mL. A beach advisory is issued for sites that have between 61-110 cells/100mL. Water quality is unacceptable at sites with over 111 cells/100mL.

Wet weather is a common trigger for fecal contamination. Rainfall data for the sample collection dates and the three days prior to sample collection were obtained by Riverkeeper using Weather Underground.
