美国南达科他州西部正面临严重的水资源危机。连续数年冬雪稀少、降雨不足,加之2026年夏季高温,导致许多浅井干枯或流量大幅下降1。当地居民和牧场主被迫采取各种应急措施寻找替代水源,包括到公共水站购水、购买桶装水或雇佣水车送水1。
位于南达科他州中部的农民戈登和康妮·霍伊一家的深30英尺的井已经彻底干枯1。戈登·霍伊表示:"20年来你可以相信那口井能24小时运转,它从未让我们失望,但现在它无法为我们提供足够的水"1。现年77岁的他还感慨道:"我在这里生活了一辈子,从未见过如此干旱、如此炎热、如此持久的天气"1。为了维持150头得州长角牛的用水需求,霍伊一家每次在Rapid City J&J沥青公司的水站加水需花费17美元,以填充1,300加仑的水箱1。
专家指出问题的根源在于地下蓄水层补给速度跟不上用水需求1。黑山区六个"子蓄水层"中部分区域的用水速度已超过蓄水层补给速度,长期存在水资源枯竭的风险1。解决问题的代价高昂:钻井成本约每英尺100美元,新水泵费用则在20,000至50,000美元之间1。目前,Frontier Water公司正用三辆卡车为黑山地区的住宅和牧场运送用水,每次最多运送2,500加仑1。平均家庭日用水量约150至200加仑,但农村居民正在实施各种节水措施来应对水荒1。
Shallow wells serving homes and ranches across western South Dakota have begun failing as years of inadequate winter snowfall, scarce rainfall, and intense summer heat take their toll on the region's water supply.1 Residents and ranchers are now forced to seek alternative water sources to meet their daily needs.
Gordon and Connie Hoy, farmers in central South Dakota, have watched their 30-foot-deep well run dry after decades of reliable service.1 "For 20 years you could trust that well 24/7, and it never quit on us, but now it's not providing enough water for everything we need," Gordon Hoy said.1 The 77-year-old Hoy reflected on the severity of conditions, noting that "I've lived here my whole life and I've never seen it this dry, this hot, this long."1 To supply water for their herd of 150 Texas Longhorn cattle, the Hoys now purchase water at J&J Asphalt company's station in Rapid City, spending $17 per fill-up to load 1,300 gallons into their tanks.1
The strain on water infrastructure extends beyond individual farms. Frontier Water company operates three trucks to deliver up to 2,500 gallons per trip to homes and ranches in the Black Hills area.1 While the average household requires 150 to 200 gallons of water daily, rural residents are implementing conservation measures as groundwater supplies tighten.1 Drilling new wells costs approximately $100 per foot, with replacement pumps running between $20,000 and $50,000.1
Experts warn that the underlying problem is accelerating. In parts of the Black Hills region, six "sub-aquifers" are being depleted faster than they can be naturally replenished.1 Without adequate recharge from precipitation and snowmelt, the long-term viability of the region's groundwater resources remains uncertain.
