Our environmental consulting services consist of soil morphology and geologic evaluations for wastewater treatment systems. Travis Doll, R.G, O.S.E., R.E.H.S. Doll has over 23 years of regulatory and consulting experience in the areas of subsurface investigations (i.e., geological, environmental and geotechnical) and onsite wastewater treatment systems (OWTS) across the State of Missouri using tec
hniques such as soil borings, test pits, monitoring well installations and collection of soil, rock, and groundwater samples. Doll is licensed as a Registered Geologist (R.G.) in Missouri; Registered Onsite Soil Evaluator (O.S.E.) – Missouri Department of Health & Senior Services (DHSS); and a credentialed Registered Environmental Health Specialist (R.E.H.S.) through the National Environmental Health Association. From 1999-2009, he was the Environmental Public Health Coordinator for Johnson County (Missouri) Community Health Services. In that capacity, he specialized in OWTS design review and inspection. Through the completion of the DHSS Advanced OWTS Installer Training, Consortium of Institutes for Decentralized Wastewater Treatment (CIDWT) Installation of Wastewater Treatment Systems certification training, coursework in soil science, and with over 20 years of experience in the OWTS field, he has developed an advanced understanding of OWTS technology and the regulatory requirements of the DHSS, county health departments and the Missouri Department of Natural Resources (MDNR). His wastewater experience includes the design and permitting of subsurface, no discharge and discharging wastewater treatment systems for residential, commercial and municipal wastewater treatment systems. His geologic experience includes design, planning, field implementation and reporting of investigations for projects including the geotechnical evaluation of proposed sites for vertical construction, the geologic evaluation of proposed liquid-holding impoundments, the geologic evaluation of site subsurface conditions for onsite wastewater treatment, and characterization and remediation of environmentally impacted sites.
