Was any required information missing on the GW-59 report forms?
NO
if the answer to question 1 or 2 is 'YES", list in the space provided below the well identification number(s) and
explain the problems encountered in obtaining the required information. The PH or temperature could not be recorded
3
Are any of the monitoring wells in need of repair or maintenance (damaged casing, unlocked or missing cap,
NO
identification plate, area overgrown, etc.)? If the answer is "YES" contact the Regional Office for guidance.
4
Are any monitored constituents equal to or above the established standards?
YES
If the answer to question 4 is ,sip to section
If the answer to question 4 is "YES", list the affected wells induvidually with constituent(s) and concentration(s)
exceeding standards in the space provided below:
