be submitted after the established due date?
2 Was any required information missing on the GW-59 report forms? YES
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.
3 Are any of the monitor wells in need of repair or maintenance(damaged casing,unlocked or missing cap,missing YES 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? Q 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:
MW1-pH below desired range @ 5.9 mg/L
MW3-ph below desired range @ 5.6 mg/L
5 For the constituents identified in question 4 above,have standards been exceeded previously for the ES NO
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.
If the answer to question 5 is"YES";list in the space provided below, each well with constituent(s)exceeding
standards, concentration(s)reported, and sample collection date for each occurrence(for the last two years).
Monitoring Wells 1,2,&3 are consistently at or below the desired range.
6 Are the monitoring wells listed in section 5 located at or beyond the review boundary? YES NO
If the answer is"YES";a groundwater quality problem may be occurring. CONTACT THE REGIONAL
OFFICE IMMEDIATELY FOR GUIDANCE.If the answer is"NO";monitoring wells may be improperly
