  1. Animal Feeding Operations Unit • Land Application Unit • Groundwater Protection Unit • Groundwater Planning Unit • Groundwater Investigation Unit • (DWQ Drill Team) AQUIFER PROTECTION SECTION Protecting North Carolina’s Water Resources

  2. Cattle • Swine • Poultry • Horses Animal Feeding Operations Unit Permitting and Compliance For Animal Operations Lagoon Spray Field Swine Houses

  3. Permit Numbers Cattle 218 Poultry 22 Swine 2201 Animal Feeding Operations Unit Distribution and Numbers of Permitted Animal Operations

  4. Lagoon Condition: Barns: Fields: Proper Waste Level Marker Vegetative Cover Freeboard Level Overall Condition Tanks/Pits Crops – Type and Condition Irrigation System/equipment Application Area Evidence of or potential for discharge Subsurface Drains Animal Feeding Operations Unit Compliance Inspections

  5. Animal Feeding Operations Unit Performance Standards for New or Expanding Swine Farms • Eliminate discharge of animal waste • Substantially eliminate ammonia emissions • Substantially eliminate odor • Substantially eliminate disease transmitters and airborne pathogens • Substantially eliminate nutrient and heavy metal contamination

  6. Surface Irrigation (Spray/Drip) • High Rate Infiltration • Reclaimed Water Utilization • Land Application of Residuals • Closed-Loop Recycle Systems Land Application Unit Permitting and Compliance For Non-Discharge Systems:

  7. Land Application Unit Program Benefits • Allows wastewater treatment and disposal while avoiding a surface discharge • Part of a successful NPDES program • Reuses a waste as a beneficial product • Conservation of potable water resources • Supplement to fertilizer products • Protects human health and the environment • Disposal based on hydraulics and nutrient loading • Must meet surface water and groundwater quality standards

  8. Land Application Unit • The beneficial reuse of treated wastewater resulting in conservation of the State’s water resources • Golf Course Irrigation • Irrigation of parks and common areas • Industrial process or cooling water • Dust suppression and soil compaction • Toilet flushing and fire protection in commercial/industrial facilities Reclaimed Water Utilization

  9. Groundwater Protection Unit • Underground Injection Control Program • Single Family Residence Permitting • Groundwater Remediation System Permitting • Well Construction Compliance & Enforcement

  10. Groundwater Protection Unit • Most heat pump wells • In situ groundwater remediation • Aquifer Storage and Recovery • Tracer injections • Closed-loop groundwater remediation (“Non-discharge” permit required) Injection Wells Requiring Permits

  11. Groundwater Protection Unit • Subsurface system rejected (hydraulically limited) • County Health Department • On-Site Wastewater (Division of Environmental Health) • Wastewater systems specifically designed for single-family residences. • Controlled surface application of wastewater effluent on vegetated land surface. Single Family Systems Requiring Non-Discharge Permits

  12. Groundwater Protection Unit Well Construction Compliance & Enforcement • More than half of North Carolina residents rely on ground water as their sole water source. • Standards for well construction can be found in 15A NCAC 02C. • Compliance and enforcement of well construction standards are part of DWQ’s overall pollution prevention strategy

  13. Groundwater Planning Unit Improve and prioritize groundwater quality protection by: • Resource Characterization & Monitoring • Regulatory Program Studies • Contaminated Site Investigations

  14. Groundwater Planning Unit Resource Characterization And Monitoring Goals • Determine & monitor ambient groundwater quality • Identify factors that affect contaminant movement • Identify natural hazards in groundwater quality Probability of obtaining groundwater with arsenic >0.001 mg/L

  15. Groundwater Planning Unit Goals of Regulatory Program Studies • Determine groundwater quality impacts of human activities • Determine effectiveness of regulations & BMPs Nitrate concentrations and groundwater ages beneath fields fertilized with swine lagoon effluent and conventional fertilizer.

  16. Groundwater Planning Unit Contaminated Site Investigation Goals: • Identify source of contamination • Determine factors affecting movement of the contamination • Recommend ways to minimize exposure • Identify alternative water supplies DWQ delineation of groundwater nitrate plume at a subdivision developed on a former agricultural site

  17. Groundwater Investigations Unit Support Resource Characterization, Monitoring, and Contamination Investigations by: • Construction of monitoring wells • Logistical and technical support for geophysical logging, aquifer tests, and groundwater sampling
