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 @ 5.88 mg/L, TOC above 10 mg/L @ 14.0
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?
S
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 are consistantly at or below the desired pH range.
Elevated Nitrate levels ccurred previously
Elevated TOC levels have occurred previously
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 maybe occurring. CONTACT THE REGIONAL
