+-- Correct two problems in the population of barcode_scans in 0067.sql:
+
+-- Problem 1: valid sample status should be 'sample-is-valid' rather than 'valid'
+-- per request from wet lab to revert to original terminology.  Change ALL instances
+-- of 'valid' to 'sample-is-valid'.
+UPDATE barcodes.barcode_scans
+SET sample_status = 'sample-is-valid'
+WHERE sample_status = 'valid';
+
+-- Problem 2: filled site_sampled was used as a proxy for having collection info,
+-- but environmental sources don't have site_sampled filled in when they
+-- are collected.  Identify all scans of barcodes that are part of American Gut,
+-- are associated with a source, are for a sample of the type "environmental", and
+-- have been collected by the participant (as evidenced by the sample_date field
+-- being filled).  Additionally, look only at scans meeting the above criteria
+-- that additionally were done AFTER the participant-reported sample_date (so after
+-- the sample was collected) AND that have a sample_status of "no-collection-info".
+-- Given the foregoing conditions, this status is incorrect as the sample is valid;
+-- change sample_status in these cases to 'sample-is-valid'.
