• Based on the available data, shallow groundwater appears to flow to the southeast.
• The primary constituents above the NC 2L Standards are limited to benzene, ethylbenzene, n-
propylbenzene, and naphthalene. However, these constituents continue to show a general
downward trend in the injection performance monitoring wells. Although other VOCs were
detected, their concentrations were below the NC 2L Standards.
Per this Notice of Regulatory Requirements:
• Continue annual monitoring (October) by conducting a groundwater sampling event of
monitoring wells MW-1, MW-3, MW-4, MW-12, and MW-13 and supply wells in October 2019.
• The next report should include a map with water supply well locations and a table with related
ownership information, well operational status, well usage, and access permission status in
accordance with the most recent version of the Guidelines for Assessment and Corrective Action
for UST Releases.
• The next report should include the locations of permanent injection wells on at least one map.
• Add Gross Contaminant Levels for groundwater onto relevant tables in the next report.
• The next monitoring report is due by November 30, 2019.
Please note that sampling, correction action, and reporting must be conducted in accordance with
the Guidelines for Assessment and Corrective Action for UST Releases. Failure to comply in the manner
and time specified may result in the assessment of civil penalties and/or the use of the other enforcement
mechanisms. See the following link for April 18, 2017 Monitoring Report Guidance and Templates
