(November2023 ) Will this monitoring report (GW-59 and GW-59A) be submitted after the established due date? YES NO 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 identification plate, area overgrown, etc.)? If the answer is "Yes", contact the Regional Office for guidance. YES NO 4 Are any monitored constituents equal to or above the established standards? ES 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 @ 6.28mg/L, TOC above 10 mg/L @ 10.7 MW2 - TOC above 10 mg/L @11.2 MW3 - ph below desired range @ 5.76 mg/L 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? ES NO 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 consistantly at or below the desired range. Elevated TOC levels have occurred previously 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 maybe improperly located; contact the Regional Office. 7 Is the permittee implementing previously approved actions required by the Division involving this groundwater quality problem? YES NO If the answer to question 7 is "YES", describe those actions in the space provided below. If the answer to question 7 is "NO", contact the Regional Office within 90 days; an evaluation may be required to determine the impact the waste disposal system is having at the review and compliance boundaries surrounding this facility. Failure to do so may subject the permittee to a Notice of Violation fines, and/or penalties. g The person completing this portion (GW-59A) of the monitoring report should sign below and submit this form with GW-59 forms for required wells to the address provided at the top of the current GW-59 form.
