Letter Report – Small Scale Injection Follow‐up Monitoring December 2019  Page 3 of 4            Measurements obtained in October 2019 when compared to data from April 2019 showed the  following:     Dissolved Oxygen – A substantial decrease in DO was seen in well MWD‐5, while a moderate  drop was shown in MW‐8.  Levels of DO in MW‐4 and MWD‐9 also dropped, only slightly.   DO in MW‐1 increased slightly.     pH – A substantial decrease in pH was seen in MW‐4, while levels of pH in MW‐8 remained  high (>12).  Levels of pH remained relatively stable in the remaining wells.        Specific Conductance – Specific conductance remained relatively stable in the wells, with the  exception of a slight decrease measured in MW‐8.          Oxidation‐Reduction Potential ‐ ORP measurements remained generally stable over the April  – October 2019 period, excepting a substantial increase in MW‐4 and moderate decrease in  MWD‐5.      Analytical results for the groundwater samples obtained from site monitoring wells on October  22, 2019 showed one or more petroleum compounds in each of the wells sampled at  concentrations exceeding their respective 2L Standards.  Samples from each of the wells showed  general increases in contaminants (based on total BTEX concentrations) over the April 2019 data.   Total BTEX increases in MW‐8 were substantial over the April 2019 results.  Charts showing total  BTEX concentrations in over time are included as an attachment.      The increase in contaminants identified in the wells sampled during October 2019 may relate to  contaminant rebounding in association with groundwater level fluctuations (as previously noted,  groundwater levels averaged 2.7 ft deeper than those measured in April 2019).  Notably, benzene  was reported in the sample from MW‐8 at a concentration exceeding the 2L Standard for the  compound.  This is the highest level of benzene reported in the well to date, and may be an  indication that injection activities have liberated contaminants once bound to soils at the location.      On balance, comparison of values for the parameters measured and analytical results obtained in  association with sampling of the wells show that groundwater chemistry has been affected in such  a way as to promote continued degradation of targeted petroleum contaminants in the several  wells on the property, however, as is the case for injections of the nature completed at the site,  rebounding of contaminants appears to be occurring, possibly based on changes in groundwater  levels at the site.  .      Supply Well Sampling    WR also purged and sampled supply wells WSW‐2, WSW‐20, WSW‐21 and WSW‐22 in  association with this TA.    Supply well samples were collected from these wells following a minimum 10‐minute purge and  submitted for laboratory analysis by SM6200B.  Laboratory results for the samples showed the  presence of 1,2‐DCA and MTBE in WSW‐2 (the on‐site supply well) at levels above the NC 2L  WithersRavenel

Standards for these compounds, and IPE at a concentration below the 2L Standard.  Data for  WSW‐22 showed acetone at a concentration of 14 ug/L, well beneath the 2L Standard for the  compound.  WR believes the presence of acetone in the well to be an artifact, as the compound is  a known laboratory cross‐contaminant.      The laboratory report associated with the supply well samples and those obtained from site  monitoring wells in October 2019 is included as an attachment.      WR recommends the performance of a limited groundwater monitoring event to be conducted  during January to verify contaminant trends in select monitoring wells and the sampling of on‐site  supply well WSW‐2.      If you have any questions or concerns regarding this report, please contact us at (919) 469‐3340.    Cordially,  WithersRavenel    Kevin Buchanan Matt James, PG
