Our Arizona Water Services Group focuses on hydrogeological and environmental consulting with offices in Phoenix and Prescott and remote staff located in North and South America. The ideal candidate will have senior-level experience in groundwater flow and contaminant transport modeling for water resources and environmental consulting projects and function as the lead groundwater modeler in the modeling team. This candidate will have advanced technical, communication, and writing skills.

What you'll do

• Lead and manage technical aspects of groundwater flow and solute transport modeling projects including Conceptual Site Model (CSM) development, model design, construction, calibration, and application of numerical models as well as conducting sensitivity and uncertainty analyses.
• Lead and manage other aspects of groundwater resources and environmental consulting projects including data acquisition, data analysis, permitting support, and report preparation.
• Assist with and/or manage multiple groundwater resources and environmental consulting projects including cost estimating, proposal preparation, budget tracking, and invoicing.
• Assist with and/or manage day-to-day operations of the groundwater modeling team, ensuring on-time delivery of high-quality work and acting as the primary internal contact for project execution.
• Interface with clients as the Project Manager and Senior Hydrogeologist for projects, including but not limited to:
  • Groundwater resources studies and hydrology studies to support Arizona Department of Water Resources (ADWR) permitting programs, such as the Assured and Adequate Water Supply (AWS) determinations, Well Spacing - Well Impact studies and Underground Storage Facility (USF) applications
  • Remedial investigations/feasibility studies, including water quality studies to support Arizona Department of Environmental Quality (ADEQ) permitting programs, such as the Aquifer Protection Permit (APP) and Arizona Pollutant Discharge Elimination System (AZPDES) permit applications
  • Hydrogeologic characterization in support of developing managed aquifer recharge (MAR) sites and aquifer storage and recovery (ASR) wells, complete with aquifer impact analyses including projected groundwater mounding and potential mobilization of contaminants in the vadose zone and aquifer
• Serve as primary modeling liaison with clients, stakeholders, and federal and state regulatory personnel including meetings to discuss technical findings and project permitting requirements.
• Mentor, supervise, and train junior groundwater modelers and hydrogeologists.

Minimum Requirements

• Education: Bachelor's degree in Geology, Hydrogeology, or Environmental Science; Master’s degree preferred
