Levels of Lead and Copper in McKinney Water Supply

At the October 15, 2015 District 1 Town Hall, a gentlemen got up and spoke about the levels of lead in the drinking water, specifically in the homes of residents of McKinney east of Highway 5.  He noted that children are being poisoned and nothing is being done about it.

I’ve been hearing these poisoning claims since 2008, and have never seen any evidence to support these claims. It has always been my position for people to submit water samples to the City of McKinney for testing, if they suspected that the quality of their water, was less than acceptable.

Be aware that the EPA has established the follow LEAD and COPPER RULE, noting:

“If lead concentrations exceed an action level of 15 ppb or copper concentrations exceed an action level of 1.3 ppm in more than 10% of customer taps sampled, the system must undertake a number of additional actions to control corrosion.  If the action level for lead is exceeded, the system must also inform the public about steps they should take to protect their health and may have to replace lead service lines under their control.”

The day after the Town Hall meeting, I submitted a FOIA request for the latest water testing results for Lead and Copper.

In 2013, the City of McKinney samples water from various locations east of Highway 5 and submitted the samples for Lead and Copper testing at an independent laboratory, the Environmental Laboratory Services.

The following were the results. For simplicity, all the units have been changed to PPB (Parts Per Billion).

Date Collected Location COPPER LEAD Date Analyzed

6/10/2013 918 Greenville Rd 128 0.408 6/19/2013

The 2015 City of McKinney Water Quality Report notes no quality problems, and clearly, all samples had levels, well below the unacceptable limits.

The City of McKinney responded:

November 2, 2015     

To Whom It May Concern:   

The City of McKinney does not have any lead water mains.  There are a total of 12 lead and copper samples sites east of Highway 5. These sample sites were established and approved according to TECQ’s  requirements (290‐117-Regulation of Lead and Copper) to monitor and report levels of lead and  copper.  

Since our system has been meeting or exceeding all pertinent regulatory requirements, we were able to reduce our sampling frequency to every three years at the reduced number of sampling sites.

Therefore, there are currently 8 active sites for lead and copper monitoring, east of Highway 5.  The last testing for lead and copper was conducted in 2013.  All tests indicated levels of lead  well below the allowable limits (test results attached).
