Beach Sanitary Surveys

Background

A sanitary survey is a method of investigating the sources of fecal contamination to a water body. Sanitary surveys are typically used for drinking water, shellfish, and watershed protection programs. They can also be used at beaches. Sanitary surveys help state and local beach program managers and public health officials identify sources of beach water pollution, assess the magnitude of pollution, and identify priority locations for water testing.

Beach sanitary surveys involve collecting information at the beach, as well as in the surrounding watershed.

Information collected at the beach may include:
  • number of birds at the beach,
  • slope of the beach,
  • location and condition of bathrooms, and
  • amount of algae on the beach.
Information collected in the watershed may include:
  • land use,
  • location of storm water outfalls,
  • surface water quality, and
  • residential septic tank information.

Beach managers can use the sanitary survey results to prioritize state or county resource allocations to help improve bathing beach water quality. In addition, they can use sanitary survey data (e.g., bacteria levels, source flow, turbidity, rainfall) to develop models to predict bathing beach water quality using readily available data.

EPA developed a beach sanitary survey tool, one each for marine and Great Lakes beaches, to help beach managers evaluate all contributing beach and watershed information including water quality data, pollution source data, and land use data. The tool consists of three types of beach sanitary surveys, in paper and electronic form (so that the data can be entered and stored in a database).


Marine Beach Sanitary Survey

EPA updated its beach sanitary survey tool to include survey forms that can be used at marine beaches. As templates, EPA used the survey forms the Agency had developed for the Great Lakes and developed a Routine On-site Sanitary Survey and an Annual Sanitary Survey that are specific to marine beaches. The survey forms include detailed questions on winds, tides, and other characteristics that affect marine beaches and were not included on the surveys for the Great Lakes.

Marine Sanitary Survey Webinar

On March 25, 2014, EPA held a webinar to introduce the Marine Sanitary Survey Tool, summarize key sanitary survey elements, and provide presentations from practitioners with their perspectives on the use and benefits of the sanitary survey tool.

Great Lakes Beach Sanitary Survey

The Great Lakes Beach Sanitary Survey has been developed and piloted in the Great Lakes, however it can be used in any beach environment (marine water, inland water).

Great Lakes Regional Collaboration Strategy

A May 2004 Executive Order created the Great Lakes Interagency Task Force and encouraged creation of a Regional Collaboration of National Significance to address environmental problems. In December 2005, the Great Lakes Regional Collaboration (GLRC) published the Great Lakes Regional Collaboration Strategy to protect and restore the Great Lakes.

Of the Strategy's eight priority elements, the Coastal Health Chapter specifically addresses beach water quality. To that end, EPA is working with the states to develop beach sanitary surveys to identify sources of contamination at Great Lakes beaches.
