Course Description:

The aerial extent of proposed sewage systems in design or land development is based on landscape slope groups and soil types.  These dictate the selection of conventional and/or alternate technologies.  These, in turn, dictate the quantity and spacing of soil test pits, the length to width ratio of beds, the cover berm slopes, and the stacked height of materials.  When sewage systems are constrained by maximum isolation distances from boundaries, rights of way, and easements, conflicts can arise.  Sewage system representation on plans is much more than placing six dots from a perc test.


Laurel F. Mueller is President/Owner and Certified Professional Soil Scientist (CPSS) for Soil Services Company, Inc, a consulting firm she started in 1984.  Laurel started Mountain Wastewater Management in 2008 to sell and service alternate technology sewage system components. 

Laurel represents CPSSs at Soil Science Society of America (SSSA), and is national chair for SSSA Consultants Division.  She is a PA Sewage Enforcement Officer, a member of PASEO, a Pennsylvania Septage Management Assocation (PSMA) Instructor for Onlot Wastewater System Inspections, and a PSMA Board member.  She served on the Board of Pennsylvania Association of Professional Soil Scientists (PAPSS) and as national president of National Society of Consulting Soil Scientists (NSCSS).  

Her expertise includes soil classification, high-intensity soil mapping, hydraulic conductivity, hydric soils, wetlands, stormwater, geomorphology for archaeology, expert testimony, and sewage facility planning, designs and maintenance.
