Permit#WQ0002708 Q
Department of Environment& Natural Resources
Division of Water Resources-Information Processing Unit
1617 Service Center
Raleigh, NC 27699
As a part of the permit renewal application,the City of Raleigh submitted monitoring data showing that the
naturally occurring background concentrations exceed the groundwater quality standards for arsenic, iron,
and manganese. Per 15A NCAC 02L .0202(b)(3), the Permittee had applied to the Director to establish
background concentrations and site-specific water quality standards for these parameters. Final
determination of background concentration for arsenic, iron,and manganese were pending upon issuance
of the final permit.The monitoring data submitted by the City was collected consistent with the Division's
requirements as they applied in 2010 and the monitoring data was gathered and analyzed by a consulting
firm the Division has recognized as competent to make such determinations at the Neuse River Wastewater
Treatment Plant's biosolids application fields. It was requested by the City that until additional site specific
• data is approved by the Division,the Division would apply the City submitted data as the best available scientific
evidence of the naturally occurring groundwater conditions for arsenic,iron and manganese at the Wrenn Road
Spray Irrigation Facility.
This report submission shows manganese data above the permitted levels and PH data below the permitted
range for the groundwater standards listed in attachment"C"of the permit.The historical manganese and
PH data provided in a 1990 consultant report as part of a land treatment site evaluation and the 2010
consultant report submitted during the most recent permit renewal process shows background data
consistent with current manganese and PH levels and should be considered as naturally occurring
background water quality.
In attachment C, footnote 8 of the final permit, it states that the Division shall use enforcement discretion for
any apparentground water standard violation for arsenic,iron or manganese until background concentrations and
site-specific groundwater quality standards can be determined. V V

(Submit one each monitoring period with GW-59 forms.)
1 Enter date monitoring results were due.(•4/3412021—) Will this monitoring report(GW-59 and GW-59A) YES NO
be submitted after the established due date?
2 Was any required information missing on the GW-59 report forms? YES 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.
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 ")es",contact the Regional Office for guidance.
4 Are any monitored constituents equal to or above the established standards? YES 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:
MW3 pH5.30 MW8 pH 5.41 MW9 pH 5.87
MW8 Manganese-185ug/I MW9 Iron-373ug/I
5 For the constituents identified in question 4 above,have standards been exceeded previously for the YES 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).
The pH's forMW3,MW8,and MW9 are in the standard range for the City of Raleigh •
Iron and Manganese are new groundwater characteristic listed in the new permit
See the attached document regarding the constituents
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
OFFICE IMMEDIATELY FOR GUIDANCE.If the answer is"NO", monitoring wells may be improperly
located;contact the Regional Office.
