Quality Assurance Program

In carrying out its mission, NHDES relies upon many different types of scientific data that enable it to better evaluate and measure existing environmental conditions, to identify and understand areas of concern, to assign responsibility for these areas, and to promote dialogue among a diverse group of stakeholders on environmental issues.

The data NHDES collects must be scientifically defensible, and the quality of that data must be appropriate for its intended uses. NHDES, through its Quality Assurance System (QAS), is moving toward a more systematic approach to the management of data and overall quality assurance issues across the department. This QAS is described in the NHDES Quality Management Plan (QMP) and is frequently updated to highlight the evolving improvements to the system.
