Ia other words, the Dradieted poetmining TD9 value at site FG6 ie 661 mg/1 (not • <br />465 mg/1). The 685 mg/1 value observed this year is only 79. greater than the <br />predicted value. Since the m aximum TDS value obeesved during the same time <br />trams at 1QPDE9 015 was Daly 540 mg/1, and since NPDES 009 did not discharge this <br />year, it can ba concluded that the 685 mq/1 value is a result o{ natural year- <br />to-year variability. <br />rings.
