Her approach to work is steady, hands-on, and rooted in the values of service, sustainability, and family.

Site & Soils Evaluation Field Days

Site and Soils Evaluation Field Days are offered for those interested in learning more about performing detailed site visits and designing systems for difficult situations and soils. These training workshops provide information on assessing soil structure, texture, and consistence, assessing site conditions and constraints, logging information and applying that knowledge to the design of onsite wastewater systems. This provides a valuable opportunity to gain hands-on experience evaluating a site, as well as practicing hand texturing and sampling. These field workshops are a requirement for those completing the Onsite Wastewater Practitioner Training Program and also add value for experienced designers and installers wishing to continue their education.
