Subject: Water Quality Monitoring Report June 2023
Harrisburg Road Landfill, Permit 60-01
Dear Ms. Drummond:
Mecklenburg County conducted semi-annual water quality monitoring at the closed
Harrisburg Road Landfill June 7 and June 8, 2023 in accordance with the approved
revised sample and analysis plan dated May 11, 2004. Additionally, wells HBW-28,
HBW-20, HBW14, HBW14B, HBW14C and HBW14D were resampled for VOCs on
June 28, 2023, due to a laboratory error. Samples were collected from eleven monitoring
wells (HBW-12A, HBW-1213, HBW-14, HBW-14B, HBW-14C, HBW-14D, HBW-1713,
HBW-20, HBW-21, HBW-22 and background well HBW-28) and three surface -water
sampling locations (H132006, HB2008 and, 1-1132010). Laboratory analytical data, field -
measured data, and a table of results exceeding water quality standards along with a
preliminary explanation of the cause and significance are included on the electronic data
deliverable (EDD) submittal.
The EDD containing the monitoring data are labeled to reflect the units that are used for
reporting. Detection levels and applicable standards have been included for all sampling
locations. Surface water standards listed are the water quality standards established for
freshwater classification for aquatic life as outlined in 15A NCAC 213 "Classification and
Water Quality Standards Applicable to Surface Waters of North Carolina". Groundwater
standards listed are the standards outlined in 15A NCAC 2L "Classification of Water
Quality Standards applicable to the Groundwaters of North Carolina". If the sample is
reported in parts per billion, then the standard is also reported in parts per billion.

Surface -water samples:
The surface water at the sampling location 2006 was more turbid than usual during the
sampling event. A construction project just upstream of the HB 2006 sampling location
was causing excess sediment runoff in the stream. The following metals were detected at
HB 2006: Barium 47.6 ppb, Copper 12.6 ppb, Vanadium 19.9 ppb and Zinc 13.1 ppb.
Barium was detected at HB 2008 and HB 2010 at 16.0 ppb and 38.3 ppb, respectively.
No other analytes were detected in the surface water samples. Field -measured parameters
for surface -water samples were within the range of established standards and are
summarized in the table below.
