Onsite wastewater disposal systems are a commonly used practice in Georgia. The Georgia Environmental Health
Department regulates this practice. Design of systems is based upon observed soil characteristics. The investigating soil scientist,
engineer or geologist provides an Estimated Percolation Rate dependent on observed soil characteristics for most systems. In the case
of an advanced system or special situation, percolation (or Ksat) is measured in the field. The common measurement methods used
are often cumbersome or fragile. The Aardvark Soils Borehole Permeameter is designed to be rugged and , transportable, with the
option for and optionally automationed. First used in the field ten years ago, this method has proven to be reliable. In 2010
Soilmoisture Inc. joined with Aardvark Systems International to produce an automated version (with manual options) that greatly
increases production rates and report capability. Testing at The University of Georgia’s new Department of Crop and Soil Sciences
Department research farm, The Iron Horse Farm, is successfully, and quickly, acquiring design data for onsite wastewater disposal,
irrigation and tile drainage. Testing for this study is concentrated on onsite wastewater disposal systems where type and size are
chosen based on Ksat rates.
