Intervals

 

 

Intervals

The Intervals table is used to record data about the vertical intervals at which measurements are taken.  They may for instance be used to record the depth of well screens or soil sample depth intervals.  The contents of the Interval field must be unique for a given Location value, but multiple wells can share a single screen name.  For example wells MW-1, MW-2 and MW-3 may all have the common Interval field value of S, but well MW-1 may not have two records with Interval values of S.  Each Location value in the Interval data table must correspond to a value in the Location field in a record in the Locations data table. 

(This table was known in versions prior to EnviroInsite 2016 as the Screens table.  EnviroInsite is backwards compatible and can still read files with a Screens table instead of the Intervals table.)
