The university issued this statement Thursday afternoon:
Test results of the water collected from the University of Houston and sent to a City of Houston lab have come back negative. Based on these results, the City of Houston, which supplies the water, has informed us the tap water on the UH campus is safe for consumption. At this time, the recommendation against drinking tap water on campus is lifted.
UH dining services and effected retail establishments are expected to resume full operation tomorrow at breakfast. Until then, limited service will continue. Dining updates may be found at http://univofhouston.campusdish.com or on Twitter at @UHDining.
Please continue to visit the emergency website (www.uh.edu/emergency) for regular updates regarding this emergency situation.
The city told abc13 that all of their testing came back negative for any microbial bacteria. The water at UH, from the city's standpoint, is clean and safe to drink. The Texas Commission On Environmental Quality tests, as well as tests from a third-party lab are not back also deemed the water safe.
Many students refused to take showers because of the discolored water.
"We had to use water bottles to brush our teeth, wash your face and skip the bathing. I guess I'm just gonna use a bottle water to wash my hands and to wash up."
University officials said they noticed the water discoloration Tuesday evening. The city quickly arrived for testing and flushed out the water overnight.
The University of Houston sent water samples to a private lab for further testing.
UH made portable WaterMonsters available at the following locations: Cougar Place, Bayou Oaks, Calhoun Lofts, Cougar Village I&II courtyard and the Quadrangle. The school also handed out free water bottles and made sure food trucks were on hand to sell hot meals since the restaurants were closed until further notice.
