Geocomputation Data Scientist

Updated: about 2 months ago
Location: Cincinnati, OHIO

The Center for Environmental Solutions and Emergency Response (CESER) plans, coordinates and conducts an applied, customer-driven, national research and development program to improve decision making by EPA, federal, state, tribal and local agencies, when faced with challenging environmental problems in the built environment. Within CESER, the Land Remediation and Technology Divison (LRTD) plans, coordinates and conducts an applied, national, customer-driven research program that delivers innovative and effective technologies, guidance, and tools to manage the nation’s land resources in a more sustainable and productive manner. 

One research program in LRTD focuses on managing contamination from underground storage tanks. There are more than 550,000 active Underground Storage Tanks (USTs) nationwide storing petroleum and other hazardous substances, and about 55,000 leaking underground storage tanks. Releases from underground storage tanks pose a threat to ground water and drinking water supplies nationally. Additionally, this infrastructure is especially vulnerable to extreme precipitation events.


  • Controlling contamination from UST sites is conditional on a number of factors. 

These factors have been included in the DRASTIC model. This model is built on seven geospatial data layers that include Depth of water, net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone, and hydraulic Conductivity. This research will build on this model to better understand contaminant transport and options in controlling contamination, under a range of conditions, including extreme precipitation events. This vulnerability model will provide a dynamic representation of the relative risk to ground water from an UST release. Additionally, this model will enhance the conceptual and predictive capabilities in understanding the role of flooding on contaminant transport and impact to water supplies. These risks include potential impacts to public ground water wells and private domestic wells. The model will be validated through empirical plume length, depth, and attenuation rate data and field studies. Improvements in this model will allow the assessment of an UST contaminant release for a hydrogeologic setting to be systematically evaluated by state and tribal partners. 

As a team member, you will assist LRTD staff with the duties required to support and maintain projects on the characterization and control of contamination from underground storage tank sites by completing the research activities described below:

  • Assisting in developing improvements to the DRASTIC model;
  • Assessing influence of extreme precipitation events and flooding on contaminant transport;
  • Incorporating extreme weather events and contaminant transport in the DRASTIC model;
  • Perform geocomputational analysis and data visualization;
  • Data analysis using spreadsheets, graphical software and modelling; and
  • Assist with developing products such as presentations and technical manuscripts.

Required Knowledge, Skills, Work Experience, and Education:

  • Proficiency in geocomputation and data visualization;
  • Proficiency in GIS, R and Python;
  • Experience in methods for geolocation of private domestic wells;
  • Demonstrated leadership skills and experience working in teams; and
  • Proficiency with Microsoft Office applications (i.e., Excel, PowerPoint, Word and Outlook), desktop publishing.
