Not held here: a discharge permit's own limits, and any rule for arsenic outside the 14 instruments we hold for this place and the places above it. A row missing here is missing from our sources, not from the law.
Free check: send your permit or your lab results, and we check each number against these rows, every verdict cited to its page, by email within 5 business days. Or send the link to a rule we do not hold: we read it and cite it by page.
Every instrument we hold for Ontario (CA-ON) and the place above it, Canada (CA): 14 instruments, for every parameter name matching “arsenic”: arsenic, arsenic 3, arsenic v, arsenic iii, arsenic total, total arsenic, arsenic dissolved, arsenic trivalent, arsenic extractible, total arsenic marine, arsenic iii dissolved, total arsenic freshwater, and 10 more (in the JSON).
