The water boil in Aransas Pass continues while crews search for the leak that caused a drop in water pressure, causing the boil notice last week.
The leak is underwater and in a swampy area, making it difficult to find.
Crews spent part of yesterday draining certain areas and manually walking the water line hoping to find the leak.
Members of the Corpus Christi Fire Department were also on scene with a drone equipped with thermal imaging to assist Aransas Pass crews.
This morning, the city will get some extra help from a crew in McAllen who will bring larger equipment to help in the search for the leak.
