Data Centers

Data center owners, operators, and managers face environmental risks from their daily operations. While these facilities are necessary to support internet infrastructure, they operate much like industrial facilities. Running thousands of computers around the clock generates significant heat that requires constant management. To prevent equipment overheating and downtime, data centers rely on large cooling systems, backup power units, and regular maintenance. Although these operations support virtual data, the infrastructure needed to run them can introduce significant pollution risks.

Air Emissions

Data centers house large arrays of industrial diesel backup generators to ensure uninterrupted uptime. These generators are routinely turned on for testing and maintenance, and they run continuously during local power grid emergencies. An increasing number of modern data centers use on-site natural gas turbines or fuel cells to generate their own primary power. Generator and gas turbine operation can result in local emissions of carbon monoxide, nitrogen dioxide, and unburned methane. Emissions from malfunctioning equipment can exceed permit limits and cause regulatory violations. Air emissions can pose health hazards to third parties.

Water

Many data centers rely on evaporative cooling towers. As water evaporates in cooling towers, dissolved solids and minerals become highly concentrated. To prevent scale buildup, this highly concentrated, mineral-heavy water, often treated with biocides, algaecides, and corrosion inhibitors, must be flushed out. This operational wastewater ("blowdown") can introduce thermal and chemical pollution into local municipal sewage or stormwater systems, potentially damaging downstream Publicly Owned Treatment Works and resulting in civil fines, regulatory violations, and cleanup costs.

Spills

As data centers transition to direct-to-chip or immersion liquid cooling to handle high-density AI chips, they store thousands of gallons of synthetic dielectric fluids and glycol-based coolants. Operational leaks or improper handling during maintenance can cause these synthetic chemicals to seep into local soil and groundwater. Many specialized fire suppression systems (used to extinguish electrical fires without damaging servers) and liquid cooling fluids contain per- and polyfluoroalkyl substances (PFAS). Routine testing, system flushes, or accidental deployments can result in a release into the surrounding soil and groundwater.

E-Waste

Server components, solid-state drives, and backup batteries have short operational lifespans (typically 3 to 5 years). The continuous process of pulling, wiping, and discarding old components generates electronic waste containing toxic heavy metals such as lead, cadmium, and mercury. If these materials are mishandled or stored improperly on-site prior to disposal, they can leach into the surrounding soil and groundwater.

Noise

Data centers require rooftop chillers, exhaust fans, and air handling units that run continuously throughout the day. This produces a constant, low-frequency hum that frequently exceeds 70 to 80 decibels at the property line. This chronic noise pollution can severely impact the mental health and sleep cycles of nearby residents, resulting in bodily injury claims.

Environmental Pollution Liability Can Provide Coverage For

Off-site cleanup of new and pre-existing pollution conditions

Third-party claims for bodily injury and property damage

Third-party claims for cleanup

Both sudden and gradual pollution conditions 

Aboveground and underground storage tanks

Business interruption resulting from pollution conditions 

First and third-party transportation pollution liability

Mold, bacteria, viruses, legionella, and more 

Loading and unloading

Defense of third-party claims

Civil fines and penalties

Illicit abandonment

Non-owned disposal sites

Claims Scenarios & Examples

During an equipment update for high-density AI servers, a valve on a liquid-cooling tank failed, allowing over 1,200 gallons of cooling fluid to leak through an unsealed gap in the concrete floor. This spill contaminated the soil beneath the building and traveled directly into the local shallow groundwater table. The data center had to remove contaminated soil, install groundwater monitoring wells, and pay legal defense fees, totaling $345,000 in damages.
An error in a valve sequence at a data center triggered an accidental, automatic flush of concentrated wastewater from a cooling tower. This water, which contained high mineral levels and treatment chemicals used to keep the system clean, bypassed onsite holding tanks and emptied directly into a city storm drain, contaminating a local stream. The incident resulted in fines from the local wastewater authority, cleanup efforts for the stream, and payments for environmental damage totaling $185,000.
Nearby residents of a data center filed a joint lawsuit claiming that noise levels caused severe sleep loss and negative health impacts. An investigation determined that the continuous, around-the-clock operation of large rooftop cooling and exhaust systems created a constant, low hum that consistently exceeded 78 decibels. The data center had to defend against the lawsuit, which resulted in a settlement payout to the neighborhood and the installation of new sound barriers to reduce the noise. The total cost reached $220,000.

Final Consideration

Your business can be faced with the cost to defend itself against allegations or legal action from pollution related events, regardless if you are at fault or not. Having the proper insurance coverage in place will help fund the expenses incurred to investigate or defend against a claim or suit and provide you with environmental claims handling expertise.
