I'll make sure I don't buy your property! You could probably pour 50 pounds
of dichromate in your septic system and not notice anything in the short
term, until neighbors or their children have strange health problems years
later or until someone has their water analized, in which case the entire
neigborhood's property value is down the drain because the water won't be
safe for the next 50 years...
The above may be a worst case scenario, but it has happened.
BTW, use gloves to handle dichromate and a dust mask is a good idea.
