what can be expected from a water test and septic inspection?
With water testing you can expect to test for Bacteria (e-coli, coliform), Lead, and Nitrate-Nitrites.
With septic sytems there are different tests, ranging from simple dye tests, to septic load tests which are more complicated
It depends on your location and the local requirements/Standards of Practice.
Here in Texas, Selman Home Inspection inspects septic systems using the “load test” method, inspection of the tanks (if accessible), using a “sludge judge” to determine if a tank needs to be pumped out, and a visible inspection of the drain field.
