Real estate (NAICS 5311): stack tests in District of Columbia, 2025

A stack test measures what a source actually emits, at the stack, against the limit in its permit. Each row is one stack test recorded during 2025 at a District of Columbia source whose primary industry code is NAICS 5311. A facility filing more than one industry code is counted under the first one on its record.
