D5549-19 – Standard Test Method Technical Guide
This guide outlines the essential contents for a comprehensive geostatistical site investigation report, ensuring all necessary information is included for evaluation by other geostatisticians. It is primarily intended for environmental and geotechnical applications, emphasizing the use of geostatistics to understand spatial variability in soil, rock, and fluids.
📐 Scope and Application
Section 1.1 specifies that a complete report must contain all information necessary for understanding and evaluation. Section 1.2 indicates that supplementary information is not discussed, while Section 1.3 focuses on environmental and geotechnical applications. The standard references basic geostatistical methods from established texts, as listed in the table below. Sections 1.4 through 1.8 highlight that this guide does not recommend specific actions, is not a substitute for professional judgment, and must be applied with consideration of project-specific aspects. It was developed in accordance with international standardization principles.

🔍 Key Geostatistical Principles
Geostatistics is a framework for data analysis in media with erratic spatial variability but spatial continuity, as seen in soil and rock from site investigations. This guide ensures that reports contain all necessary information for geostatisticians to understand and evaluate the investigation. It highlights the importance of using established methods and integrating site-specific knowledge.
💡 Note: The guide emphasizes that geostatistics is not intended to establish cause-and-effect relationships, and investigations should incorporate supplementary knowledge from other sources.
⚠️ Important: This standard does not recommend a specific course of action and should be used with professional judgment. Not all aspects may be applicable in all circumstances.
❓ Frequently Asked Questions
🔍 What is the purpose of this guide? It covers the contents required for a complete report of a geostatistical site investigation, ensuring all necessary information is included for evaluation by other geostatisticians.
💡 Does this guide cover all geostatistical methods? No, it focuses on basic methods and does not discuss multivariate, space-time, or less-frequently used methods.
⚡ What are the key references for geostatistical methods? The guide references texts by David, Journel and Huijbregts, Clark, Isaaks and Srivastava, Olea, Chiles, and Goovaerts for detailed descriptions.
📌 How should terminology be defined in the report? Common technical terms should be defined according to ASTM D653, Terminology Relating to Soil, Rock, and Contained Fluids.
