(c) In examining the scant list of trash registered at the landfill,
you noticed that NISO4 was allowed on the compound and was
mistakenly deposited as regular garbage. The record showed that
1.5kg was brought into the landfill.
The environmental standard of nickel in waterways should not
exceed 0.17mg/L of Ni to prevent acute toxicity to organism. The
volume of the leachate pond is estimated at 15000L. Assuming that
all the NiSO4 ends up in the leachate pond, would the
concentration of Ni exceed the standard?
