North Lake ReleasesMy environmental staff has been looking into the source of the poor
water quality that has recently appeared at our Bachman Water Treatment
Plant intake. The problems are originating from the releases from North
Lake as part of your ongoing project. Preliminary data show that the
releases violate stream standards for Segments 0822, 0825 and 0826 for
both chlorides and Total Dissolved Solids (attached). The violation
occurs even with the dilution from our Grapevine and Lewisville Lake
releases.
Can you forward to me any correspondence with TCEQ concerning this
project that you are aware of? In the meantime, I would suggest that the
release either be stopped or reduced to lessen the impact on Dallas’
operations and customers.
Thanks.
