Quality Assurance
At Stone Environmental, we know how data quality impacts environmental decisions and project results. That’s why we require all projects be conducted professionally, with a high degree of integrity and ethics. Our in-house Quality Assurance Unit (QAU) sets standards for our team members, provides training, and maintains a comprehensive Quality Management System to deliver results of the highest quality.
Stone requires all environmental data operations collect data of known and documented quality, suitable for its intended use and in compliance with all applicable regulatory and contractual requirements. Our QAU staff has substantial experience with a range of compliance requirements backed by an understanding of analytical methodologies, method validation, data assessment, and data validation.
