District, City of Southlake Conduct Water Testing of Schools

After several cities and school districts across the nation found unacceptable levels of lead in their drinking water, Carroll ISD reached out to the City of Southlake to proactively conduct testing of the water in every CISD school building.

This testing by trained city officials was not required or mandated but is the result of a voluntary decision by CISD Administration to ensure quality drinking water in local school facilities.

A total of 27 water samples were tested, including water in the kitchen area and one water fountain in each of the district’s 11 schools, the Aquatics Center, Dragon Stadium and the Administration Center.

All of the samples taken in CISD passed the lead test. The Environmental Protection Agency has determined an acceptable limit of 15 parts of lead per billion parts of water. All CISD samples passed the water test and fell below EPA guidelines for lead.

In addition to testing for lead, city officials tested for the presence of copper. All but one of the 27 test samples passed the copper test. One water fountain at Carroll Middle School had slightly higher than acceptable levels of copper. It was a water fountain that got little to no use during the summer months and officials believe this could be the reason for the slightly elevated levels of copper in the water.

Based on this one test, the district immediately turned off the identified water fountain and as a precaution, the one next to it. The lines were flushed and for an extra measure of assurance, CISD requested additional testing of 17 other fountains throughout the CMS campus.

The EPA and Texas Commission on Environmental Quality (TCEQ) consider public water systems to be in compliance if the laboratory results for 90% of the samples collected (90th percentile) are below 15 parts per billion (ppb) for lead and are below 1.3 parts per million (ppm) for copper. The fountain that did not pass the initial test at CMS had 1.5 ppm for copper.

A second round of testing has now been completed. All of the water samples in this second round of testing at CMS met the required EPA and TCEQ requirements.

CISD is committed to safety, and while the slightly-elevated level of copper posed little to no risk to middle school students, school officials wanted to be sure the fountain was not in use until proper levels of copper were maintained. Passing this second round of testing was an important step in ensuring confidence in CISD’s water system.

School officials say they are pleased to be able to work successfully with the City to ensure safe water levels.  To learn more about the City of Southlake water sampling program, visit their website at

West Nile Virus Off-Season Testing Begins November 19

Off-season trapping will begin November 19 and continue until March 25. During this time the City will trap mosquitoes once every two weeks and test once a month. Due to the high volume of mosquitoes in the area, samples will be taken from a trap at 870 Shady Lane. Results from these tests will continue to be posted on the Mosquito Surveillance page on the City’s website. Weekly testing will resume at the start of next year’s full season on April 1.

Fire Hydrant Testing – 100% Completed

Beginning February 20th through April 15th, the Southlake Department of Public Safety’s Fire Services division will be testing the City’s fire hydrants.  The annual testing is necessary to ensure that all fire hydrants are fully operational in the event of a fire emergency.  This testing will also verify that all fire hydrants are able to maintain the required water flow necessary for putting fires out quickly.

Fire Hydrant Testing

Fire Chief Michael Starr says, “The testing of all of the City’s fire hydrants is necessary to ensure the safety of Southlake residents. Our number one priority is being able to protect our citizens from any fire danger.”

Hydrant testing is performed during low consumption and water usage times.  This is done to ensure that any necessary maintenance or repairs can be made with limited impact to Southlake’s water system.  Fire Services employees will diligently monitor the amount of water flow during the testing procedures to minimize the amount of water usage necessary to ensure correct operation and flow rates.

If you have any questions about the scheduled fire hydrant testing, please contact Deputy Fire Chief Wade Carroll at 817-748-8146.

**UPDATE — We have completed 100% of the fire hydrant testing as of April 3rd, 2012.
