PROFESSIONAL EXPERIENCE SUMMARY

Mr. Maley is both a licensed professional geologist and civil engineer with over 30 years of experience in
groundwater management, water resources, regulatory support and environmental projects. His
extensive water resources experience includes groundwater basin evaluations, sustainable yield
estimates, water quality evaluations, groundwater‐surface water interactions, and groundwater recharge
programs. Through this work, he has evaluated the sustainable yield and groundwater quality for many
heavily‐used groundwater basins for groundwater management plans in California. He has developed and
applied integrated groundwater‐surface water models and water quality analysis to assess groundwater
impacts for feasibility studies and CEQA/NEPA support for large engineering projects including percolation
ponds, injections wells, recycled water, and wastewater disposal.

Mr. Maley is a specialist at applying groundwater models using MODFLOW‐MT3D, GSFLOW, IWFM and
FEFLOW. He has demonstrated the capability to successfully calibrate complex models through close
attention to the physical processes that govern groundwater flow and contaminant transport. Models
developed by Mr. Maley have undergone rigorous peer, regulatory, and expert review. Through his
experience, he has provided valuable insight into the hydrogeological controls that influence groundwater
flow from large groundwater basins to local engineering projects.

Mr. Maley evaluated groundwater impacts from implementation of a series of prioritized management
actions detailed in the WAP. The analysis evaluated groundwater conditions that may be adversely
impacted over time as a result of re‐direction of Kern River release water. Mr. Maley used a MODFLOW
superposition model based on the USGS Central Valley Hydrologic Model (CVHM) for the analysis.
