Step 1.2 Gathering Health Concerns and Other Information

Quadrant Mapping

Quadrant mapping is one method for gathering and organizing data during a site visit. By using this or other methods consistently, health assessors will become efficient and thorough in gathering information that is needed about a site.

The steps for using a quadrant mapping system:

Step 1
Divide the site into four quadrants.

Step 2
For each quadrant, sketch important features (for example, source areas, streams, and wells).

Step 3
For each quadrant, complete table noting site characteristics that can impact exposures (for example, site access and vegetative cover).

Step 4
After the site visit, review information to help identify exposure pathways.
