Continuing the discussion from Data Centers…Why not regulate them to our advantage:
A small to average size data-center consumes an enormous amount of energy. In addition, they require a small staff, typically 8-15 people. However, consider the following:
1) potential stress on groundwater quantity,
(2) risks to groundwater and lake water quality,
(3) heavy energy and infrastructure demands, and
(4) loss of land permeability and ecological function.
These risks are magnified when a data center sits close to a drinking‑water well and surface water bodies.
1. Groundwater Depletion Risks
Data centers—especially AI‑focused or hyperscale facilities—use very large volumes of water for cooling. Even mid‑sized centers can consume as much water as a small town, and large ones may use millions of gallons per day.
For a community well serving ~100 homes, this matters because:
-
Groundwater withdrawals by the data center could lower the water table, reducing well yield.
-
Drought conditions could worsen the impact, since the aquifer’s ability to recharge may be limited.
-
The National Ground Water Association warns that data centers often rely on groundwater and must be carefully evaluated to ensure the aquifer can sustain the added demand.
Why this is a con for your community:
Your well is close to the proposed site. If the data center taps the same aquifer, your drinking‑water supply could face competition or long‑term decline.
2. Groundwater and Surface Water Quality Risks
Even if a data center does not directly “pollute,” its water use and discharge can worsen existing contamination or introduce new risks.
Documented concerns include:
-
Concentrated pollutants: Recycling cooling water can concentrate contaminants already present in the source water.
-
Thermal discharge: Warmed water released into lakes or soil can alter ecosystems.
-
Chemical risks: Cooling systems may involve biocides, corrosion inhibitors, or other chemicals that must be carefully managed.
-
Stormwater runoff: Large paved areas increase runoff carrying oils, metals, and other pollutants into nearby lakes or groundwater.
Why this is a con for your community: Any contamination or thermal change in the lakes or surrounding soils could migrate toward the well, depending on groundwater flow direction.
3. Enormous Energy Demand and Infrastructure Strain
Data centers require massive electrical power, often equivalent to tens of thousands of homes. Some hyperscale centers use as much electricity as 100,000 homes.
This can lead to:
-
New high‑voltage transmission lines
-
Substation expansions
-
Increased noise from transformers and backup generators
-
Higher local electricity rates if infrastructure upgrades are subsidized by residents
Why this is a con for your community:
Even if the land is privately owned, the infrastructure burden is public—your township may face noise, visual impacts, and grid strain.
4. Loss of Natural Land and Increased Flooding Risk
Data centers typically cover tens to hundreds of acres with buildings, concrete, and parking. This reduces natural infiltration and increases runoff.
-
Impermeable surfaces can redirect water toward your well field or lakes, altering hydrology.
-
Flooding or erosion risks may increase.
-
Local wildlife habitat is lost.
The Lincoln Institute notes that large data centers can consume hundreds of acres, replacing farmland or natural land with impermeable surfaces.
5. Noise, Vibration, and Aesthetic Impacts
Even “lights‑out” data centers (with few employees) produce:
-
Constant low‑frequency hum from cooling equipment
-
Backup generator noise during testing
-
Increased truck traffic during construction and maintenance
These may not be the biggest environmental risks, but they affect quality of life.
6. Transparency and Oversight Challenges
Data centers often operate under non‑disclosure agreements and limited regulatory oversight.
The Science and Environmental Health Network notes that their water and energy impacts are often difficult to quantify due to secrecy and lack of reporting requirements.
The NGWA also warns that local governments may not be prepared to manage the resource demands of data centers.
Why this is a con for your community:
Your trustees may not receive full information about water withdrawals, discharge, or long‑term impacts.
Here are targeted questions that will reveal whether the project is safe for our wells and lakes:
-
How much water (peak and annual) will the data center withdraw? From what source?
-
Will cooling water be discharged? If so, where and at what temperature?
-
What chemicals will be used in cooling or maintenance?
-
What hydrological studies have been done on groundwater flow between the lakes and the community well?
-
What protections will be in place to prevent contamination or over‑withdrawal?
-
What infrastructure upgrades will the township be responsible for?
-
Will the operator commit to full transparency in water and energy reporting?
