Hydrogeologic Assessments

Hurvitz Environmental Services (HES) has completed over 250 hydrogeologic assessments across Northern California, providing clients with reliable evaluations of groundwater availability and sustainability. Our work supports residential, agricultural, and commercial projects, and is designed to meet county requirements and California Environmental Quality Act (CEQA) and the Sustainable Groundwater Management Act (SGMA) standards.

By combining hydrologic data, geologic mapping, and field investigations, we deliver clear, defensible reports that guide land-use decisions, permitting, and long-term water planning.

Our Hydrogeologic Assessments may include:

• Site & Basin Characterization – Evaluate local geology, aquifer systems, and watershed-scale conditions.
• Groundwater Storage & Recharge Estimates – Quantify annual recharge and storage relative to current and proposed water demands.
• Well Interference Analysis – Assess potential impacts of pumping on neighboring wells, streams, and springs.
• Sustainable Yield Evaluation – Determine long-term groundwater availability to support development or agricultural expansion.
• Water Use Estimates – Calculate existing and projected water demand using established usage rates.
• Risk Assessments – Evaluate potential for saltwater intrusion, land subsidence, or resource conflicts.

Whether you’re a private landowner, developer, or municipality, HES provides the technical expertise and practical insight needed to make informed decisions about water supply and sustainability.
