Now I will have to undergo another medical examination, as we were breathing the air teeming with bacteria. 

Or using bleach as well is harmful to the good bacteria that the system needs.  

Its 80% water, and half life is limited, and it only kills Bacteria.

They need to understand that they can't put too many chemicals down the drains because that will kill all the beneficial bacteria in the tank.

Bacteria breaks the solids down and the fluids overflow into a system of pipes into the ground.

I guess if it is, I can learn about human physiology, but I can also learn about bacterias and single celled organisms too

We  even put silver lining in our AC vents to help kill bacteria" - Was fun talking with him. 

with a septic tank you need to budget in pumping cost and with it being a rental I suggest pumping every 3-4 years. you also need to limit the amount of bleach products you use because it kills the anaerobic bacteria that makes a septic system work properly.

(It collects all kinds of bacteria, mold and fun creeping things.)

Here are the factors that we look at that contribute to the life of galvanized pipe: Internal corrosion or mineral build up is dependent primarily on the following factors assuming we are talking about cold water.Ph of water, Alkalinity of water / hardness of the waterCorrosion will also be increase in there is high levels of sulfur, dissolved oxygen,...Iron bacteria can lead to corrosion and build up at the same time.All Cities and many parks with or without their own wells are required to test for Lead and Copper this is really just a measure of the corrosive nature of the water being put through the system.
