4
Are any monitored constituents equal to or above the established standards?
IS
NO
If the answer to question 4 Is "NO", skip. to section 8.
If the answer to question 4 Is "YES" list the affected wells Individually with constituent(s) and concentration(s)
exceeding standards In the space provided below.
