Hyperion Energy Center - Surface Water Quality
The DENR water quality monitoring network is currently made up of 151 stations located on various rivers and creeks within the state. Six sampling stations were added in 2009 to the area surrounding the proposed Hyperion oil refinery location (See Map). These sites are being sampled to determine background water quality.
Typically, grab samples are collected mid-stream, either from a bridge or by wading into the stream. Every station is sampled in the same manner and location each time. When the sample has been collected, the sampler immediately obtains water and air temperatures, specific conductance, pH, and dissolved oxygen measurements. Time of sample, water depth, channel width, and other visual observations are also recorded. The samples are properly preserved and transported to the laboratory for analysis.
The area around the proposed Hyperion oil refinery location in Union County is also monitored for petroleum analytes. Several stations are sampled for sodium, calcium, and magnesium during the irrigation season. This type of water sampling is used to track historical sampling information, natural background conditions, and runoff events, and can indicate possible acute or chronic water quality problems. The lab data from the water samples collected around the project site is available to the public. Refer to the below links for the data of each water quality monitoring station. Please note that sampling events without data and a stream flow of 0 (cfs) were events in which the waterbody was dry.
