Children, seniors, and people with weakened immune systems are the most vulnerable and should follow the directions listed below.
In a press release, The Texas Commission on Environmental Quality said the Harris County public water system should notify all customers to boil their water before consumption.
"To ensure the destruction of all harmful bacteria and other microbes, water for drinking, cooking, and ice making should be boiled and cooled before use for drinking water or human consumption, " according to the release.
Boiling kills disease-causing organisms, including viruses, bacteria, and parasites.
Instead of boiling, individuals may purchase bottled water or obtain it from another suitable source for human consumption.
The public water system will issue an update once the boil water notice is no longer in effect.
