Information for BEACH samplers

The BEACH Program is a coordinated effort between state agencies, local health jurisdictions, tribal nations, and volunteers.

Collecting water quality samples

Volunteers can use this video to learn how to collect water samples. This should be used in addition to proper training.

The BEACH Program monitors beaches weekly throughout the summer. Samplers test for illness-causing bacteria, known as enterococci, by collecting three samples at each beach. Because bacteria results can be highly variable, three sample results are averaged to ensure the level of risk at the beach is accurately represented. When the average exceeds 104 enterococci/100mL, a beach advisory is issued.

More details about gathering beach water quality samples can be found in the documents below.
