| Hi all,
| Just had our 2500 gal. tank pumped by a reputable company. After
| pumping the guy dumped 20 gallons of Sulfuric acid in to break things
| up. This is a bottomless tank with no leach field.
Sounds like a cesspool.
| I expressed some concern about this practice but was assured it's
| common. Can anyone comment on whether this is really necessay and any
| environmental implications?
It certainly used to be common around here 25 years ago, both in cesspools
and in septic systems with leach fields. It also seemed to be quite effective.
However, I haven't heard of it (or concentrated hydrogen peroxide) being
allowed in years. This may be because of environmental concerns about the
chemicals themselves or it may be because (as far as I understand Massachusetts
regulation) we aren't allowed to "fix" a leach field at all. Once it fails we
have to put in a new system that is compliant with current standards. If I
lived in a location that allowed it and if an appropriately licensed service
person applied it (and if they didn't charge some absurd price for a cheap
chemical) I certainly wouldn't complain. As to whether it was absolutely
necessary, I would guess that if you were not having a problem in the first
place the answer is no...
