Enterococcus Level

Enterococcus is a bacteria that can cause illness in humans and animals.  Water can be tested for enterococcus and test results are typically available about 24 hours after samples are collected.  Results are expressed as Most Probable Number (mpn) of enterococcus per 100 ml of water.

This website provides mpn results and color indicators that are easier to understand.  PASS/FAIL at Amityville Village Beach is based on New York State 2022 Enterococci salt water standard.

NOTE: It is important to note the date the enterococcus level was collected.  Enterococcus levels can change significantly from one day to the next as environmental conditions change.  To avoid misleading people, when results are from more than 8 days ago, PASS and FAIL indicators will display in grey as OLD PASS and OLD FAIL.
