I would be surprised??? I have worked in the water and wastewater industry for the past 37 years. The places I have been and the things that I have done would make you heave chunks. And I ate lunch right after words with those same hands.
There is no problem with a properly designed septic system draining to the aquifer. It's those backyard hack jobs that cause problems.
And one more thing, dosing tanks are the preferred method of using a septic system. A dosing tank stores then discharges a larger volume of water to the septic system rather then the typical 2 gallon flush every time the commode is used. Dosing gets water out into all parts of the leach field rather then only using the first few feet repeatedly. This makes the field work better and last longer.
