The first file on the slag water samples began with sample jars, culvert flow notes and mill operating cards. The city then checked the source, heard affected residents and sent a second office to repeat the count.
The current Year first, smelt run window 1 file records 59 samples with a time, flow and operating condition attached; the previous window records 64. The longer sequence makes the change visible, while each count remains tied to its own dates.
A turning point was the observation that the culvert flow rises after the late furnace rinse. It narrowed the discussion from a general claim to a question about how the rule works at the site.
The mill tests at the end of a run. Residents ask for a sample during the rinse as well as after it. The shared record is larger than it was at the start, although the parties still assign it different weight.
Atime-limited trial begins under a dated card visible to the crew. The Year first, smelt run window 1 file remains open for its scheduled decision. The sample desk will collect paired jars before and after the rinse.
