Water Quality Status

DISCLAIMER: Like all information on this website, Water Quality Status is provided for your consideration, but is no guarantee of water quality or health outcomes if you enter, swim or interact with the water.  Always obey officially posted signs, advisories and safety guidance, and use your judgement to be safe.

Water Quality Status is based on recent or past testing at the location, or manually posted information and advisories.

The status will be one of the following nine types:

Recent Test Status

img/wqs-fail-current.png The most recent test results failed to meet water quality standards.
img/wqs-unknown-current.png The most recent test results are too old (more than 7 days old), or unavailable or unreliable.

Historic Test Status

When swimming season is over or when a location's water quality data has not been updated frequently enough (weekly) it goes into historical status.  This means that rather than displaying a recent test status, it displays the location's average water quality for the year.

img/wqs-pass-current.png Historically passed water quality tests 95% of the time or more.
img/wqs-fail-current.png Historically passed water quality tests 60-95% of the time.
img/wqs-unknown-current.png Historically passed water quality tests less than 60% of the time.

Special Status

The status can be manually set for a location if there are concerns about the testing protocol, if there is an emergency, if monitoring practices don't exist or have recently changed, or other reasons that render this location "special."

img/wqs-fail-current.png There are water quality issues or there is an emergency.
img/wqs-unknown-current.png No current water quality information, the beach is under construction, or there has been an event that has rendered water quality information unreliable or unavailable.
