About Us

The W.A. Callegari Environmental Center is part of the LSU AgCenter Agricultural Chemistry Department and serves researchers, agricultural producers, private companies, governmental agencies and the general public in the area of water quality.

Water Quality

In addition to serving agricultural interests, the laboratory provides research capabilities for AgCenter scientists, private industry and local governments. The laboratory can perform more than 40 analytical procedures to determine the chemicals in water and solid and semi-solid materials. Materials that can be tested include:

  • Agricultural runoff water (ditches or sediment ponds)
  • Ambient water (ponds and streams)
  • Well water (non-potable)
  • Animal wastes and lagoons
  • Organic byproducts (agricultural residues, agricultural processing wastes, wood and green wastes, municipal biosolids and wastewater sludges, etc.)
  • Composts and organic soil amendments (non-fertilizer sources)

The water quality laboratory employs specific analytical methodologies approved by the United States Environmental Protection Agency and the Louisiana Department of Environmental Quality for water, waste water and biosolids analyses.
