Amazon has applied to discharge up to 280,000 gallons a day of cooling water into a stream feeding Lake Anna; Virginia DEQ holds a public hearing on 9 June.

Key takeaway

Amazon's cooling-water permit can clear Virginia law while leaving residents' PFAS concern untested.

Amazon has applied to discharge up to 280,000 gallons a day of non-contact cooling water into Sedges Creek, an ephemeral stream feeding Lake Anna, from a 150-acre Louisa County campus next to Dominion Energy's North Anna nuclear plant⁠1. Virginia's DEQ (Department of Environmental Quality) holds a public hearing at Louisa County Middle School on 9 June 2026, then decides whether to grant the VPDES (Virginia Pollutant Discharge Elimination System) permit, the state framework that governs industrial water discharge.

A second Amazon facility already discharges up to 460,000 gallons a day into Northeast Creek. The water is pretreated with sulphuric acid, sodium hydroxide and other chemicals, and DEQ caps metals, temperature and chlorine. Virginia sets no PFAS (per- and polyfluoroalkyl substances, the "forever chemicals") testing requirement for data-centre discharge, which is the residents' central objection going into the hearing.

Ephemeral streams carry little water for much of the year, so their dilution capacity is low and concentration limits matter more than the gallon figure. The testing gap, not the volume, drives the objections: a permit can be lawful and still leave the community's worry unmeasured. This is the cost pushed onto a watershed and argued after the fact, the same pattern as Amazon's $20.5m Boardman nitrate settlement and the Microsoft water suit in Wisconsin.

Deep Analysis

In plain English

Data centres use enormous amounts of water to cool their servers. That water is treated with chemicals before being released into nearby streams. Amazon wants to release up to 280,000 gallons a day of this treated cooling water into Sedges Creek, a small seasonal stream that flows into Lake Anna, a reservoir in central Virginia. Residents near Lake Anna are worried about PFAS, sometimes called forever chemicals, because they do not break down and accumulate in drinking water and fish. Virginia does not currently require data centres to test their discharge water for PFAS before releasing it. Virginia's environmental regulator, the DEQ, holds a public hearing on 9 June 2026 where residents can formally object and ask for testing requirements to be added to the permit.

Deep Analysis
Root Causes

Virginia's VPDES permit framework derives from the federal National Pollutant Discharge Elimination System (NPDES), which classifies industrial discharges by Standard Industrial Classification (SIC) codes. Data-centre cooling operations fall under SIC codes for non-manufacturing water users rather than chemical-process industries, which means the permit template does not require contaminant characterisation for compounds associated with industrial chemistry.

PFAS entered the regulatory conversation only after the NPDES framework was established, and the EPA's national PFAS rules, finalised in 2024 for drinking water, have not yet been extended to industrial discharge permits in most states.

Virginia's specific gap, no PFAS testing requirement for data-centre discharge, reflects the absence of a state rule rather than a deliberate decision to exempt data centres. The DEQ hearing on 9 June is the first venue at which the gap becomes a public regulatory record, giving community groups the legal standing to demand that DEQ exercise its discretion to add testing conditions before permit issuance.

What could happen next?
  • Precedent

    A DEQ decision to add PFAS testing conditions to Amazon's Sedges Creek permit would create the first state-level precedent requiring data-centre cooling discharge to be characterised for forever chemicals, providing a template for other Virginia and potentially other state permits.

  • Risk

    Approval without PFAS conditions leaves a monitoring gap that forecloses attribution if contamination is later detected, replicating the Boardman pattern where the settlement came years after the discharge began.

Seven projects, one linked to Google, asked SEA this month for rulings that they fall outside full environmental review; four declared diesel-storage volumes just under the review-triggering tonnage, mirroring the mechanism Alto Jahuel used in July.

Ireland's planning appeals body refused the €1.5bn Killala data centre on 17 September, overturning Mayo County Council's 2025 grant for lack of a fixed grid-connection agreement and no corporate renewable power-purchase agreement.
