IF the answer to question I or 2 is "YES'; list in the space provided below the well identification number(s)
explain the problems encountered in obtaining the required information.
3 1 Are any of the monitor wells in need of repair or maintenance (damaged casing, unlocked or missing cap, missing
identification plate, area overgrown, etc.)? Ifthe answer is "Yes", contact the Regional Office for guidance.
4 +Are any monitored constituents equal to or above the established standards?
!f 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:
Nitrate levels were above standards in wells 2,3,6,7, and 9. (Concentrations in table below.)
5 For the constituents identified in question 4 above, have standards been exceeded previously for the
same constituent(s) in the same well(s) in the last two years?
If the answer to question 5 is NO'; skip to section 8.
