The Geospatial Analysis for Optimization at Environmental Sites (GRO-1) web-based guidance is designed to help practitioners better apply geospatial analyses in environmental projects. The material presented provides not only highly technical detail, but also introductory information for those who may not have expertise in this area.

The document applies to all project life cycle stages: release detection, site characterization, remediation, monitoring and closure. This document is a companion document to Groundwater Statistics and Monitoring Compliance (GSMC-1).
