    There are 2 paths to become a certified system inspector:

    2. To have completed an NSF equivalent course of instruction which MUST include a field test for both your and the property owner's safety and for liability purposes and to assess your proficiency in a real life setting.
    As a national 501(c)3 we (WasteWater Education 501(c)3 ) took over the inspector training program from NSF.
    There are several levels of training dependent upon the candidates level of expertise. To comply with we are able to provide the core 2 hour online, on demand class which includes assignments as listed above.
    In addition you must take the mandatory 60 question written exam listed above which may also be taken live online. A minimum 75% passing grade is required. Those who fail may take a refresher course to resit a new exam.

    In addition is attendance at or viewing of a mandatory 90 minutes soils and geology of Virginia class ($60), as it relates to onsite wastewater treatment. Content from this, as well as the foundation class, may be the topic of questions in the written exam.
    The foundation course deals specifically with conventional soil based systems - those seeking to evaluate advance/alternative systems will require a supplemental license. Upon successful completion we will arrange for a local field exam. Do NOT pay for that beforehand please.
