    WATER AND WASTEWATER PERMITTING AND COMPLIANCE PROJECTS

Non-Discharge Permit and Environmental Impact Assessment Support, Briar Chapel Mixed-Use Development, Chatham Co. NC

Completed detailed hydrogeologic and water balance studies in support of spray irrigation and wet weather storage components of the Environmental Impact Assessment and Non-discharge waste water permit for a 2,500-acre mixed used development.  The Hydrogeologic Study included the preparation of a three-dimensional groundwater flow model that was constrained and tested using data from piezometers and test-borings installed on the site.  Client: Newland Communities

Non-Discharge Permitting, Rockbridge Residential Development, Wake County, NC

Preparation, submittal, and regulatory negotiation for a Non-Discharge permit for a 412 lot residential subdivision in eastern Wake County.  The wastewater from this development will be treated to North Carolina Reclaimed water standards using an on-site treatment plant   Managed and prepared the Detailed Site Investigation Report which comprised the Hydrogeologic, Water Balance, Soils, Wetlands, and Geotechnical reports.  Managed and coordinated the preparation of the engineering design of the waste treatment  plant and the wet weather storage that was prepared by another design firm. Client: Stafford Land Company

Independent Expert Wastewater Loading Assessment, Governors Club, Chatham County, NC

Retained to perform an independent analysis of the capacity of the soils and vegetation on golf course fairways and other sprayfields to adequately dispose of reclaimed waste water.  Analysis is required as part of a settlement agreement between parties having an interest in the development.  The analysis requires evaluation of the capacity of a low-permeability compacted soil layer that was created during golf course construction in areas where soils contain swelling clays. Client: Kilpatrick Stockton

Non-discharge Permitting, Ridgley Hills Residential Development, Wake County, NC

Preparation and regulatory negotiation for a Non-Discharge permit for a 452 lot residential subdivision in eastern Wake County.   Managed and prepared the Detailed Site Investigation Report which comprised the Hydrogeologic, Water Balance, Soils, Wetlands, and Geotechnical reports.  Managed and coordinated the preparation of the engineering design of the waste treatment  plant and the wet weather storage that was prepared by another design firm. 

Modeling of Nitrate Loading to Neuse River from Past Biosolids Application, North Carolina

Modeling of nitrate loading to the Neuse River via groundwater and surface water discharge from biosolids application to fields near the City of Raleigh ’s Neuse River Waste Water Treatment Plant.  Loading from groundwater discharge  was assessed using a three-dimensional flow and transport model  integrated with ArcGIS™.  Loading from surface water is being assessed using the USDA Surface Water Assessment Tool (SWAT) integrated with ArcView™.  Client: City of Raleigh Public Works Department.  

Response to Notice of Violation, Municipal Spray Irrigation Facility, North Carolina

Principal investigator for responding to NOV from the North Carolina Division of Water Quality for alleged impacts to groundwater at the Elm City Wastewater Spray Irrigation Facility.  Used existing data, new field tests and measurements, and modeling to demonstrate that spray field operations were not the source of levels of nitrates in monitoring wells in excess of NC groundwater standards. The most likely source was shown to be previous agricultural operations on the property and adjacent properties.  Client: Town of Elm City .

Permit Application for spray irrigation of combined industrial and municipal wastewater effluent, North Carolina 

Principal investigator for site characterization, modeling, and monitoring in support of a permit for the disposal of treated effluent from combined municipal and industrial waste water plants.  Disposal fields comprise shallow soils overlying fractured rocks of the Carolina Slate Belt.  Client: Sheaffer International.   

Permitting  for new spray irrigation facility, food processing plant, North Carolina 

Principal investigator for conducting modeling of the hydrologic fate and transport of constituents in effluent from food processing plants that is applied using spray irrigation.  Constructed and applied models of vadose zone and saturated zone groundwater flow and transport   Made extensive use of sensitivity analyses to successfully demonstrate to the permitting agency that the site would conform to regulatory requirements, eliminating the need for additional extensive and exhaustive site investigation. Client: Bruce Foods
