About ERD



Environmental Research and Design, Inc. (ERD) was founded in 1986 by Dr. Harvey H. Harper, P.E. as a water quality research and engineering firm. Work efforts at ERD are devoted primarily to the areas of surface water and groundwater quality, stormwater treatment, lake management and restoration, sediment/water interaction, and sediment inactivation.

Field Expertise
ERD maintains one of the most complete inventories of sampling and monitoring equipment for surface water, stormwater, groundwater, rainfall and sediments of any engineering firm in the Southeast. ERD also has shop facilities for fabrication of specialized equipment to meet unique applications.

Laboratory Facilities
ERD maintains an in-house research-grade water quality laboratory, which is NELAC certified (No. E1031026) for general parameters, nutrients, heavy metals, demand parameters, and microbiological parameters. Additional equipment is available for water quality analyses, algal bioassays, toxicity testing, jar testing, coagulation experiments, and sediment incubation/ release experiments. Since laboratory analyses are conducted only on surface waters and stormwater, laboratory methods have been optimized for low detection levels.
