Rain vs. Ecoli Graphs
Note:

  • E. coli = The number of E. coli per 100 milliliters.

  • Geomean = The geometric mean of the three samples taken at a particular location (Right, Center, Left). 

  • Total Body Contact is ≤ 300 E. coli/100 ml. 

  • Partial Body Contact is ≤ 1000 E. coli/100 ml.

  • If the result was recorded as <10 a 9 was recorded in the table.

  • Sampling is performed on Mondays and results are reported by the Friday of that week (from  April through October).

  • The amount of rain is recorded in inches.

  • Significant Rain Events (>1/4 inch in 48 hours) may increase the E. coli count making the water unsafe for recreational activities
