Multiple areas in northwest Harris County, Texas, are under a precautionary boil water notice due to a temporary loss of water pressure caused by a valve replacement. Residents between Mason Road and Grand Parkway along Highway 290 are advised to boil water for at least two minutes before consumption. The Harris County Municipal Utility District is collecting water samples, with results expected by Monday, August 5. Meanwhile, Chester, Massachusetts, has been under a boil water order for over a week due to treatment violations, severely impacting local businesses and residents. The community has rallied together, with some residents providing well water and bottled water being distributed at the fire department.
