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. I'm a first time
home owner with a dangerous amount of knowledge.
I expressed some concern about this practice but was assured it's
common. Can anyone comment on whether this is really necessay and any

Sounds like a cesspool.

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...
It was done routinely in the 50s and 60s. The hug-a-tree folks get
excited about any thing with the word acid but in reality sulfuric acid
will not do any damage when used in this manner.
