The Ways Data Centers Use, Dispose Of Water Isn’t Easy To Understand – Or Legislate
Indiana faces challenges managing its water resources amid a data center boom, with environmentalists concerned about water consumption, chemical discharge, and temperature impacts on aquatic ecosystems. The state is developing a statewide water management plan, but critics worry that data center development is progressing too rapidly. Locals are also pushing back against these developments.
The article, originating from TheStatehouseFile.com and published by InkFreeNews.com, highlights escalating concerns over Indiana's water resources in the face of rapid data center development. Dan Boritt, executive director of the Indiana Wildlife Federation, voiced alarm that the pace of data center expansion, consuming vast amounts of water and energy, is outpacing the state's capacity to assess and manage its water supply, potentially causing significant harm to aquatic ecosystems.
Indiana Governor Mike Braun signed an executive order to create a comprehensive statewide water inventory and management plan by the end of 2026, addressing a long-standing need for such a strategy. Despite this, environmental groups and local residents are apprehensive that new data center projects, including Microsoft's campus in La Porte and the controversial LEAP District in Lebanon, will intensify water issues before the state's plan is finalized. Community members are increasingly opposing these developments due to their scale and environmental implications.
The piece elaborates on the intensive water use by data centers for evaporative cooling, noting that large facilities can consume billions of gallons annually. Concerns extend to the quality and temperature of discharged water, which may contain concentrated chemicals like biocides and phosphates, as well as heavy metals and PFAS. Such discharges, even if permitted, could disrupt aquatic life and promote harmful algae blooms due to altered water chemistry and elevated temperatures. The increased volume of water directed to wastewater treatment plants also raises questions about their capacity to handle the additional load.
The article concludes by emphasizing the lack of comprehensive data on data centers' water footprints, contributing to the uncertainty. The Indiana Wildlife Federation, while not opposing data centers outright, advocates for rigorous environmental accountability to prevent ecological damage.
