Just want to add my support to what Laurie wrote below.

LIMS are just fancy databases for storing laboratory data.  In the very old days, laboratory results would have been stored in something like an Excel, or Lotus 123, spreadsheet, but modern LIMS are a lot more sophisticated than just a simple database, and can assist not only with the storage of results, but also the scheduling of sampling.  But LIMS are only capable of storing discrete results.

SCADA systems are set up to capture data from online analysers that read close to continuously, and then compare these results with set limits.  Within water safety plan (WSP) frameworks, SCADA is great for monitoring the performance of critical control points (CCPs), especially breaches of the alert and critical limits associated with the CCPs.  To analyse trends over time, you really need to send raw SCADA data to something like a SCADA Historian storage arrangement.

Important difference in the two data sets is that LIMS store discrete, point in time data, whereas SCADA stores continuous data.  I am not aware of any system that can meaningfully combine laboratory data with SCADA data.

Within the WSP framework, SCADA data hopefully prevents you from supplying unsafe drinking water, where laboratory data in a LIMS tells you whether you did supply safe drinking water.
