Not held here: a discharge permit's own limits, and any rule for lead 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 “lead”: lead, lead total, lead acetate, triethyl lead, lead phosphate, lead ii acetate, lead subacetate, tetraethyl lead, tetramethyl lead, lead ii phosphate, total lead marine, total lead freshwater, and 5 more (in the JSON).
