Population impacted by Boil Water Notices in Texas, U.S. 2020

The severe weather conditions that hit Texas in February caused by storm Uri not only affected the state's electricity supply, but also water facilities. Many utilities across the state faced water pressure issues, leaving millions of residents without safe drinking water. This led to Boil Water Notices (BWN) being issued, which come into effect when unsafe water conditions arise. This means boiling water is needed for anything from washing food to brushing teeth. Whilst the number of people impacted began to fall as the storm eventually eased and BWN's were lifted, 1,259 BWN's were still in effect as of February 22, impacting roughly 8.7 million people across the state. At this time, the number of people still affected by BWN's in Texas were highest in the counties of Bexar, Travis and Harris.

二月份，由风暴乌里引发的恶劣天气不仅影响了德克萨斯州的电力供应，亦波及至水资源设施。州内众多公用事业公司面临水压问题，导致数百万居民陷入无安全饮用水之困境。由此，煮沸水警示（BWN）被发布，该警示在水质不安全状况出现时生效，意味着从洗涤食物到刷牙等日常活动均需煮沸水。随着风暴逐渐减弱，煮沸水警示被解除，受影响的人数开始下降，但截至2月22日，仍有1,259个煮沸水警示处于生效状态，大约870万人受到这一状况的影响。在此期间，德克萨斯州受煮沸水警示影响的人数在贝雅、特拉维斯和哈里斯等县达到最高。
