Key takeaway

Virginia regulators heard objections to Amazon's Lake Anna discharge, with the draft permit requiring no PFAS testing.

The Virginia Department of Environmental Quality (the DEQ, the state's environmental permitting agency) held a public hearing on Tuesday 9 June on Amazon's application to discharge 280,000 gallons a day of data-centre cooling water into Sedges Creek, which feeds Lake Anna in Louisa County. The hearing drew objections and produced no permit decision. ¹

Data centres pull vast volumes of water through their cooling systems and must return the warmed, treated outflow somewhere; here that somewhere is a creek running into a reservoir used by nearby residents and by Dominion Energy's North Anna nuclear plant. The application traces back to the permit Amazon filed with the DEQ for this discharge , and the 9 June session was the public's first formal chance to contest it.

The sharpest objection concerns what the draft permit leaves out. As written, it carries no requirement to test the discharge for PFAS, the per- and polyfluoroalkyl compounds known as "forever chemicals" because they do not break down in the environment. Without a testing condition attached to the permit, neither regulators nor residents would have a baseline for what enters the watershed once the campus begins releasing water.

The DEQ has not ruled. Whether it adds a PFAS monitoring condition before approving the discharge is the open question, and it will set a marker for how Virginia, the densest data-centre market in the world, polices the water side of the boom rather than the power side.

Deep Analysis

In plain English

Amazon wants to discharge 280,000 gallons of water per day into a small stream called Sedges Creek in Louisa County, Virginia. That stream feeds Lake Anna, a reservoir used by local residents and, critically, by a nuclear power station called North Anna, which uses the lake for cooling. A public hearing on this water permit was held on 9 June 2026 by Virginia's environmental regulator. The main concern at the hearing was PFAS, also known as forever chemicals: a group of man-made chemical compounds that accumulate in water, soil, and living things and do not break down naturally. They have been linked to health problems including some cancers. Amazon's proposed permit, as currently drafted, does not require any testing for PFAS in the water being discharged. Residents and environmental groups objected. Virginia DEQ ended the 9 June hearing without issuing a decision; the permit review continues. Data centres use large amounts of water to cool their servers. The water picks up chemicals from the cooling towers before being discharged, and those chemicals can include PFAS. The question of what data-centre cooling water contains, and whether it needs to be tested before being discharged, is largely unsettled in US environmental law.

Deep Analysis

Root Causes

Two structural gaps explain why Amazon's draft permit carries no PFAS testing requirement. First, Virginia's VPDES framework specifies only parameters that EPA has designated as regulated pollutants for the industrial discharge category in question.

PFAS are regulated for drinking water systems under EPA's April 2024 rule, but the rule explicitly excludes industrial discharge permits pending a separate rulemaking. Virginia DEQ cannot add PFAS conditions unilaterally without a federal hook, because Amazon would challenge the condition as ultra vires.

Hyperscale campuses use proprietary anti-corrosion and anti-fouling chemical packages in their cooling towers, and the downstream discharge composition of those chemicals in combination with ambient water chemistry in a specific reservoir like Lake Anna has not been studied. Virginia DEQ and EPA both lack published research on what hyperscale cooling discharge contains in combination with reservoir chemistry.

What could happen next?

Risk
Virginia DEQ's draft permit, if issued without PFAS conditions, creates a template for other hyperscale cooling-water permits across the 13 states in the Northern Virginia data-centre corridor, where similar VPDES permits are under review.
Short term · Assessed
Precedent
The Lake Anna hearing is the first US data-centre cooling-water public hearing to explicitly raise PFAS; if Virginia adds a monitoring condition, it becomes the model for other state VPDES permits pending EPA's industrial discharge PFAS rulemaking.
Medium term · Reported
Risk
Dominion Energy's North Anna nuclear licence conditions depend on Lake Anna water quality. A cooling-water contamination event would trigger dual NRC and state regulatory review, adding a nuclear utility as a potential third-party claimant against Amazon.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Amazon's $20.5 million settlement in May 2026 over nitrate pollution from its Boardman, Oregon data-centre cooling discharge is the structural precedent for the Lake Anna hearing: it established that cooling-water discharge from hyperscale campuses can produce actionable environmental liability, gave community groups a financial template for litigation, and placed Virginia DEQ under notice that a permit issued without adequate PFAS conditions could expose the state to legal challenge if cooling-water contaminants are later found in Lake Anna.

Virginia's regulators will be aware of the Boardman settlement when writing the final permit conditions.

Counter-parallel: Dominion Energy's North Anna Nuclear Power Station, which uses Lake Anna as its primary coolant source, has operated under a VPDES permit since 1978 with temperature and radiological conditions. North Anna's permit has never carried PFAS conditions because PFAS was not a regulated parameter when the permit was written or renewed.

Amazon's permit application follows the same framework, which is why it also lacks PFAS conditions: it is consistent with existing precedent, not an anomaly, and that consistency is precisely the problem critics are raising.

Dominion Energy's North Anna Nuclear Power Station uses Lake Anna as its primary coolant source under NRC (Nuclear Regulatory Commission) licence conditions that require monitoring of the lake's thermal and chemical properties. A PFAS contamination event in Lake Anna would trigger NRC permit review for North Anna as well as Virginia DEQ action for Amazon.

That dual-regulatory exposure makes the Lake Anna permit decision unusually high-stakes for Dominion Energy as a third party: Dominion's North Anna operating licence depends on lake-water quality standards that Amazon's discharge permit could affect.

The $20.5 million Boardman, Oregon settlement is the current ceiling for data-centre cooling discharge liability in US case law. A Lake Anna contamination event would likely set a higher figure given that the lake also supports recreational use and supplies cooling water to a nuclear plant, adding multiple plaintiff categories beyond the agricultural and environmental parties that sued in Oregon.

Consensus view: WRI Aqueduct's water-risk mapping places Lake Anna in a medium-high water-stress zone, and the Virginia Environmental Law Journal has documented that Virginia's water discharge permitting process for industrial sites predates data-centre cooling loads by 40 years: the VPDES (Virginia Pollutant Discharge Elimination System) permit framework was written for manufacturing-scale discharge volumes, not the continuous 280,000 gallon per day flows that characterise evaporative cooling at hyperscale density, meaning the regulatory mechanism Amazon is working through was not designed for this use case.

Counter-view: American Rivers (a national non-profit waterway advocacy organisation) argues the Lake Anna hearing is the wrong venue for the structural question: Virginia's draft permit process is focused on temperature and nutrient limits, not PFAS, because PFAS is not currently a VPDES-mandated parameter for industrial discharge.

The real policy gap is that the EPA's PFAS in surface water rules, finalised in 2024 for drinking water, have not been extended to industrial discharge permits; absent federal action, no state-level hearing can impose PFAS testing Amazon has not agreed to.

Key tension: Whether Virginia DEQ will add a PFAS monitoring condition to the final permit under public-comment pressure, or whether the absence of a federal VPDES PFAS requirement gives Amazon grounds to contest any state-imposed condition as exceeding Virginia's regulatory authority.

Lake Anna hearing, no PFAS test

The hearing exposed a regulatory gap: a hyperscaler can clear Virginia water law without any requirement to test its discharge for the persistent chemicals communities most fear.

Different Perspectives

Antel, Uruguay's state telecom

Antel will build a $70m AI data centre in Canelones, announced after an 11-12 August Council of Ministers meeting, with construction from Q1 2027 and roughly 250 direct jobs. Uruguay is putting a sovereign AI facility on the state balance sheet rather than courting a hyperscaler to build one.

Comtel

Comtel is building a Figline Valdarno data centre inside the H2-Era Green Valley complex, powered by an 84 MW solar plant and selling waste heat to on-site farming. Co-location with generation and a heat offtaker is the model regulators elsewhere are now writing into connection terms rather than negotiating case by case.

Greg Abbott, Texas Governor

Abbott directed PUCT and ERCOT on 3 August to audit every queued data centre's ownership, incentives and water use, saying projects that fail the state's survey should lose grid access. QTS's co-chief executives welcomed the review; Agriculture Commissioner Sid Miller called it too vague and wants a special legislative session instead.

Government of Gujarat

Gujarat notified a Data Centre Policy on 7 August offering capital, interest, tax and duty subsidies for projects sourcing at least 51% green power, targeting 7.5 GW against a 74 GW installed base. Where other jurisdictions priced or restricted grid access this month, Gujarat is paying developers to come instead.

Taiwan's Legislative Yuan Economics Committee

The committee gave preliminary approval on 5 August to a self-generation mandate for large power users, including data centres, with fines up to NT$750,000. It agreed the obligation in principle while leaving the megawatt threshold that defines its reach to later implementing regulation.

Australian Energy Market Commission

AEMC advised ministers on 5 August that data centres should surrender renewable certificates against actual consumption, prove new demand with new firm capacity, and register as market participants. The advice would turn passive customers into obligated participants inside the market's dispatch and settlement machinery, ahead of an access-standards determination due in late October.
