Environmental Analysis Lab

We Analyze, Evaluate, and Test

The Environmental Analysis Lab is a waste management & water quality sampling and evaluation service which is used by the department, state agencies, municipalities, and other UNC system university colleges.

What we do: The lab analyzes, evaluates and tests agricultural crop residues and plant tissue, soils, solid and liquid wastes and effluent water and waste water samples for waste management, water quality, and agricultural sampling to EPA standards and protocols. It is a fee-based campus testing service center.

Types of Analysis

samples checked for susspended solids.

  • Water (e.g., ground water monitoring wells, drinking-well water, agricultural run-off,etc.)
  • Waste Water (e.g., lagoon liquid, food processing, effluent, poultry processing sludge, etc.
  • Solid Waste (e.g., poultry litter, compost, manure, etc.)
  • Soils ( e.g., waste amended soils, background soils, etc.)
  • Plant tissue (e.g., Bermuda grass, corn leaf, etc.)

The procedures are mainly EPA approved wet chemistry analyses of nutrients, mineral demand, and metals.
