East Penn Soil Consulting specializes in soil evaluations and testing, inspections, planning and design for onlot septic systems. As a Certified Professional Soil Scientist, Pennsylvania Sewage Enforcement Officer (SEO), and PSMA/NOF Onsite Wastewater Treatment System Inspector, I have over 20 years of experience in the onlot industry in Pennsylvania.

The requirements surrounding onlot septic systems can be confusing. I welcome the opportunity to have my clients present to observe site evaluations and soils testing. This gives me an opportunity to show them the soil profile and discuss with them how soil characteristics play a role in renovating effluent and in determining the type of system that will ultimately serve their project.

Clients that better understand how the soils and their systems function have a clearer picture of what’s really happening in the ground after their system is constructed. As a result, they are better equipped to maintain and extend the life of their systems, to protect both their family’s health and the environment.
