• Delaware historical thermoelectric water context

  Historical2015 state thermoelectric power estimates, including fresh and saline water. Not current2026 conditions, data center facility use, drinking water demand, permit allocation or proof of a data center effect. Withdrawal, total water use including deliveries and reclaimed wastewater, and consumptive use are distinct. Consumption may exceed withdrawal because other supplied water is included. Independent rounding is retained; no facility joins or per kWh allocation.

• Delaware historical2020 modeled thermoelectric water context

  USGS2008-2020 thermoelectric water-use reanalysis,published annual output filtered to2020:modeled annual-mean million gallons/day,not observed current2026 water use.958plant-year rows cover48conterminous states,not a complete facility census or data center inventory. Withdrawals include fresh/saline rows;consumption at coastal saline plants was not modeled.54Once-through saline source zero-consumption placeholders are excluded from consumption sums,not measured zero. State best/lower/upper figures are calculated sums of source plant model estimates and thermodynamic plausibility limits,not statewide statistical confidence intervals. Do not compare directly with2015county compilation as a measured trend;methods differ. HUC12 IDs and county labels do not certify parcels;README says public model-input coordinates use interpolated HUC12 centroids,not precise plant locations. No source coordinates adopted,site joins,permit/sustainable availability/datacenter allocation or causal inference.
