Previous Causes of Impairments Now Attaining All Uses


Description of this table
Fecal Coliform 2002, 2004, 2006, 2008 Oct-22-2008 Applicable WQS attained; reason for recovery unspecified. Recent sampling data indicates a geometric mean of 196 cfu/100mL which does not exceed the Fecal Coliform geometric mean criterion of 400 cfu/100mL; and only 4 of 18 samples (22%) exceeded the screening limit of 400 cfu/100mL.
Lead 2008 Feb-10-2012 Applicable WQS attained; reason for recovery unspecified.  
Selenium 2002, 2004, 2010 Oct-22-2008 Applicable WQS attained; reason for recovery unspecified. Recent sampling data indicates that no samples exceeded the Selenium criterion of 5 ug/L.
Turbidity 2006 Oct-22-2008 Applicable WQS attained; reason for recovery unspecified.
