Takeaways from the DEQ Report

When the Virginia Department of Environmental Quality’s (DEQ) finally released their  report on groundwater availability last month it was shocking to many in the groundwater management area.

The Major Takeaways from the Report:

  • Groundwater levels across the vital Potomac aquifer are projected to enter a sharp, renewed decline within the next 5 to 10 years under existing conditions.
  • Just the two paper mills (located in Franklin and West Point) account for 43% of all reported groundwater withdrawals, creating massive underground "cones of depression".
  • Decades of falling water levels have caused land subsidence (sinking) that is accelerating. The land has subsided below sea level, causing irreversible saltwater intrusion into the fresh drinking aquifer.
  • Private domestic wells  which need neither a permit or have monitoring make up 34% of groundwater withdrawals (estimated). They are believed to be the fastest-growing drain on the aquifer that DEQ completely lacks the authority to regulate. These numbers are all estimated since there is not data on use for private wells. ** (see note below)
  • Due to these constraints, any new water-intensive industry like  a data center using evaporative cooling cannot be accommodated by the available groundwater supply.

However, the most shocking disclosure was that DEQ’s historical regulatory oversight via the groundwater  management area has essentially been irrelevant to active conservation of the Coastal Plain Aquifers. The factual timeline of the Potomac Aquifer demonstrates this point perfectly:

  • When the Franklin mill closed in 2010 due to the recession, groundwater levels in the Potomac Aquifer rose to levels not seen since the 1960s. This dramatic rebound was entirely an economic accident, not a result of DEQ regulatory prowess. 
  • As soon as economic activity picked up and the mill reopened at a lower production rate in 2012, that entire rebound vanished. Other regional users had quickly consumed the temporary surplus, and by 2021, the aquifer began a renewed steady decline. 
  • Even when the DEQ swooped inmoved to aggressively renegotiate and "slash" the permitted limits of the 14 largest industrial users, the cuts reductions were mostly cosmetic. Regulators scaled the permitted caps down to match what the manufactures were already actually using, changing virtually nothing about the real-world volume of water leaving the ground. 

The report fundamentally exposes the Eastern Virginia Groundwater Management Area as a bureaucratic boundary rather than an effective ecological shield. Because the DEQ cannot mandate alternative surface-water switches or stop private well drilling, the declaration of a "management area" has done nothing to alter the water use math dictating the aquifer's decline. 

The global data on aquifer interventions validates this point that labeling a boundary on a map is irrelevant if it does not enforce physical changes in water demand. A landmark 2026 global study published in Science by Dr. Scott Jasechko analyzed 67 successful groundwater recovery stories across six continents and found that mere administrative oversight lacks ecological impact.

The global data reveals why the DEQ’s approach failed and how real recovery actually happens:

The Illusion of "Paper" Management

The Science study notes that 81% of true groundwater success stories relied on introducing an alternative water source to physically offset pumping demands. In contrast, the DEQ’s management area strategy focused on rewriting permit levels on paper. Because those cuts only matched what industries were already pumping, the intervention required zero behavioral change and resulted in zero actual water savings.

Why the Franklin Rebound was a False Success

The study highlights the "impermanence of groundwater recovery," explicitly warning that economic shifts can instantly erase temporary aquifer gains. The 2010 Potomac aquifer rebound occurred purely because the Franklin mill shut down during a recession. Because the DEQ's management area failed to permanently retire that water allocation or legally mandate a switch to surface water, regional users quickly swallowed up the temporary surplus the moment economic activity picked up.

The Cost of Inaction is Irreversible Sinking

The global assessment confirms a harsh geologic reality for the Virginia Coastal Plain while proper interventions can slow down or stall land subsidence (sinking) caused by excessive pumping, the ground sinking (subsidence) is entirely irreversible. Every year the DEQ operates an "irrelevant management area without enforcement teeth that actually limit groundwater use, the regional infrastructure and coastal topography suffer permanent, unfixable structural compression. The compressed land that has subsided will never hold water again.

To move past symbolic boundaries and fix the regulatory loopholes, the Virginia DEQ's report outlines 11 specific recommendations submitted to the General Assembly. Rather than attempting to manage the problem with existing weak rules, the DEQ is explicitly asking lawmakers to rewrite the Ground Water Management Act of 1992 to grant them actual enforcement power.

The primary solutions suggested by the DEQ to fix the aquifer depletion include:

1. Striking Down Permits Based on Alternative Availability

The DEQ requested the statutory authority to deny or heavily limit any groundwater withdrawal permit if an alternative water source is physically available. This would allow regulators to legally force industrial giants (like the paper mills) or future data centers to connect to available surface water or recycled municipal water instead of drilling deeper wells into the Potomac aquifer.

2. A Hard Freeze on New Industrial Permits

The department recommended that lawmakers explicitly prohibit the DEQ from issuing any new permits for significant groundwater withdrawals within the designated management areas. This serves as an immediate "stop-loss" measure to prevent new water-intensive industries from accelerating the aquifer's collapse. 

3. Aquifer-Level Trigger to Deny Applications

The DEQ is asking for the explicit right to auto-deny any water withdrawal application if the requested pumping would lower local aquifer water levels to a predefined danger point. This replaces the current reactive permitting process with a legally binding environmental threshold.

4. Forcing Municipalities to Budget Growth around Water

The DEQ suggested a legislative mandate requiring local governments to limit their long-term comprehensive growth plans based strictly on groundwater availability. This would stop local counties from zoning and approving massive residential subdivisions or industrial parks when the local geology literally cannot provide the water to support them.

5. Funding for Real-Time Infrastructure Monitoring

The DEQ requested $1.7 million in immediate funding over the next two years from the General Assembly to upgrade its science. This money is earmarked to buy real-time monitoring equipment to evaluate active groundwater recharge methods and hire dedicated compliance officers to enforce strict permit limits.

The Governor should convene a special session of the legislature because Virginia cannot continue treating groundwater depletion as a technical issue for regulators alone. The DEQ report shows that the problem is statutory, economic, and political. Regulators cannot protect the aquifer if the law tells them to keep permitting withdrawals that the resource cannot sustain. Local governments cannot responsibly plan growth if the state does not require them to confront water limits. Businesses cannot make reliable investments if the Commonwealth pretends that every site has water capacity when the science says otherwise.

Virginia’s groundwater management areas have become a warning label rather than a safeguard. The DEQ report shows that the Commonwealth knows where the danger lies, knows why existing law is inadequate, and believes they know what tools are needed to prevent further decline. What remains is political will. Calling a special session would signal that the Governor understands the urgency of the crisis and is prepared to move Virginia from symbolic management to enforceable protection of its groundwater future.

**While private well users return the water they use to the ground through their septic systems. The effect of this return in the Coastal Plain is very different that the effect in the Culpeper Basin. Unlike the fractured rock system  system of the Culpeper Basin where this water use is neutral, water from septic reaches the aquifer.  In the Coastal Plain there is a highly stratified geology made of alternating layers of permeable sand (aquifers) and impermeable clay (confining units).  The vast majority of private residential wells are drilled deep into confined aquifers which sits hundreds of feet below the surface. This deep groundwater is under pressure and has been locked away for thousands of years. This septic effluent recharges the surficial (shallow, unconfined) aquifer. It does not sink back down into the deep Potomac Aquifer because thick, dense layers of clay block it from migrating downward. Instead of replenishing the drinking water supply, that septic water and garden water use in the Coastal Plain flows laterally through the sand lay into nearby shallow creeks, rivers, and the Chesapeake Bay.
