Clarke County has abundant natural resources: the forested western slope of the Blue Ridge Mountains with 22 miles of the Appalachian Trail, 21.6 miles of the Shenandoah River and, on the western side of the river, the northern portion of the Shenandoah Valley. Underlying the Valley is limestone geology (karst terrain) characterized by sinkholes, springs, and sinking streams. Much of the county’s natural resource efforts are aimed at protecting its water resources as well as its predominately agricultural landscape and economy.
The Natural Resource Planner works with all sources of available assistance to plan for the allocation, management, and protection of Clarke County’s natural resources, sharing information about environmental issues and trends with community members. The Natural Resource Planner manages the Conservation Easement Program.

What is Karst?
A land area that includes sinkholes, springs, sinking streams, and caves. In karst areas, the fractured limestone rock formations have been dissolved by flowing groundwater to form cavities, pipes, and conduits. Sinkholes, caves, sinking streams, and springs signal the presence of underground drainage systems in karstlands. Unless watersheds are protected, these direct connections between the surface and the subsurface can threaten the quality of our drinking water. The safest watersheds are those in which all residents understand the karst landscape and work together to reduce soil erosion, high-density development, agricultural and urban storm water runoff, overgrazing, improper waste disposal, and pollution.

Did you know that there are specific places in the county that play a critical role in recharging our ground water? Water that falls as precipitation needs to find pathways to the groundwater and that happens best in the carbonate areas where sinkholes, caves, sinking streams, faults and fractures provide easy access for water to percolate down to the water table
Even in the carbonates that underlie most of the valley area, some areas are more critical than others for groundwater recharge. On the western side of Clarke County there is a limestone ridge that runs from Double Tollgate and trends to the NE crossing into WV to the east of Stones Chapel. This area, identified by the US Geological Survey is approximately 22,100 acres in size and contains the drainage divide between the Opequon Creek and the Shenandoah River. It is also a critical area for filling the groundwater that runs below the county because of its unique structure, elevation, and distance from the river, streams, and springs which discharge water from the groundwater.
Why do you care? What we do in this critical recharge area to preserve our permeable surfaces for groundwater recharge affects water availability and quality for a large portion of the county. To help protect this area, the Easement Authority is asking the Virginia Outdoors Foundation, the state agency responsible for conservation easement holdings, to designate this area as a priority project area. The purpose of the designation is to focus resources on placing properties in the recharge area into permanent conservation easement to reduce development potential on this critical resource area.
Clarke County has long been a leader in environmental protection and managed controlled growth. This is evidenced by the extensive long-term planning and visionary thinking that occurred in the early 1980's. During this time the County realized the importance of our groundwater resources and developed the Groundwater Protection Plan. This plan led to the establishment of the septic and well ordinances, sinkhole ordinance, the first USGS groundwater study, and an overall awareness of the sensitive nature of our groundwater resources from a water quality view. The County also adopted Sliding Scale Zoning, implemented the Agricultural/Forestal District, use value taxation, use of the LESA scoring system, and designated growth areas. These tools, in addition to more recent protection efforts such as the establishment of the Conservation Easement Authority and adoption of the Mountain Land Plan, have provided a strong framework to allow for growth while protecting our agricultural economy and natural and historic resources.
Water Levels - Clarke County
In 2002, as a result of a prolonged and serious drought, the County initiated a 6-year groundwater study with the United States Geological Survey (USGS). The primary objective of the study was to enhance the County's understanding of the quantity and sustainability of our ground-water resources. The following link details the results and findings of this six-year study. Monitoring will continue annually as funding is approved by the Board of Supervisors.

On July 15, 1997 the Board of Supervisors approved the adoption of a text amendment establishing standards for the application of Biosolids.
Beginning in 1998, two companies, Bio Gro and Recyc Systems applied biosolids in the County. Currently Synagro (formally Bio-Gro) and Wright Trucking spread on area farms.
In 2004, State law repealed Counties ability to regulate biosolid application beyond testing and monitoring. The change permits Counties to request reimbursement for expenses relating to monitoring and testing but eliminates increased setback standards that Clarke County had adopted to protect ground and surface water resources in sensitive karst areas. The County maintains the ordinance and requests applicators to comply.
All applications have been closely monitored by County and State representatives and have been in compliance with all requirements. In accordance with State Regulations, Counties may be reimbursed for the testing and monitoring expenses.
Beginning January 1, 2008 the Virginia Department of Environmental Quality (DEQ) assumed regulatory oversight of all land application of treated sewage sludge, commonly referred to as biosolids.
This action, which moves oversight of the Biosolids Use Regulations from the Virginia Department of Health to DEQ, was at the direction of the 2007 General Assembly, which voted to consolidate the regulatory programs so that all persons land applying biosolids would be subject to uniform requirements, and to take advantage of the existing compliance and enforcement structure at DEQ. DEQ has established an Office of Land Application Programs within the Water Quality Division to manage the biosolids program, as well as land application of industrial sludges, septage, livestock and poultry waste, and water reclamation and reuse. The Virginia Department of Health will continue to consult with DEQ and advise the public on health issues related to biosolids applications. State Web Site
Current new State regulations require:
- Nutrient Management Plan to be submitted with application
- Posting of property 48 hours prior to application
- No spreading on snow
