Data items are listed below with their measurement units.
Yield (gallons per minute)
Yield footnote:
When water quality samples are taken from wells, the static water level and/or yield sometimes also are measured. Data from some wells are stored in both the water quality database and the static water level database; the well level header provides space for cross referencing the well by its water quality reference number. There are wells, however, whose level and/or yield values are stored only on the water quality database with other parameters. If the well level database does not yield an adequate number of sites for the area of interest, then the user should check the water quality database.
