TDS levels reported as 4890 mg/I should be 4090 mg/I and sodium <br />levels reported as 2150 mgA should be 1250 mg/I. In addition, iron was reported as total iron and has been <br />correctcd to indicate dissolved iron. Revised pages containing all corrected data are attached. <br />We apologize for these errors in our reporting and hope they have not caused the Division excessive <br />review time.
