I have read about the college studies results.
I will read the labelling on the detergent carefully now.


We try to avoid dumping fats/grease down the sink drain.

What type of chemicals are your referring to ?

Is there any need to add chemicals to the seepage pits / drywells ?

What kind of chemicals would be used, if YES ?


Are chemicals used only to supplement a septic tank system ?


Septic tank/ field voo-doo. I say that because all of the makers of such
products make the claims but if you do a search you will read studies from
colleges that state that there's no need for them as long as you aren't
dumping chems and fats down the drain. The other side of the argument is
that most soaps and detergents are now anti-bacterial and will impair proper
bacterial propagation. My answer is to stop using such products for reasons
far more important than the septic tank issues. That's a different thread,
however. I stopped using the additives but I still have a strong desire to
do so.
