Heavy rain and flooding occurred this week along the Colorado River of Texas (not the river that flows from Colorado to Mexico) which flows from the Hill Country through Austin on the way to the Gulf of Mexico. The sediments derived largely from farm land have overwhelmed surface water supplies and water treatment plants so the City of Austin issued a boil water notice and water conservation measures. Boiling water before drinking will remove bacteria, parasites, and other organics. Other towns that provide deep groundwater supplies are not affected by the boil water notice.
