Details are presented below: MCL CONSTITUENT RESULT UNITS MCL LESS OR EQUAL EXCEED Organic - Primary Benzene ND ug/L 1 Pass ND=Non-Detected. MCL: The maximum level at which a constituent may be present and be considered acceptable for potability or aesthetics. Primary: Items listed as primary are regulated because of health concerns. If there is a failure for a primary constituent treatment is normally required. Secondary: Items listed as secondary are regulated because they may adversely affect the taste, odor or appearance of drinking water. They are not directly health related. If there is a failure for a secondary constituent on a small public water system it is best to consult your regulator to determine if treatment is required. A secondary constituent failure for a private water system does not require treatment. However, the owner may wish to treat the water in order to improve the quality. Treatment: If your water requires treatment we suggest that you contact a qualified water treatment company. They are normally listed in the yellow pages under the following topics: Water Purification & Filtration Equipment Water Softening & Conditioning Equipment Water Treatment Equipment Page 3 of 4 This Page is to be Stamped September 3, 2020 Lab ID : CH 2076992 Amy Rohrer Customer : 7-4502 Quality Control - Organic Constituent Method Date/ID Type Units Conc.

Blank : Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples. MS : Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample matrix affects analyte recovery. MSD : Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyte. The recoveries are an indication of how that sample matrix affects analyte recovery. MSRPD : MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation and analysis. ND : Non-detect - Result was below the DQO listed for the analyte. DQO : Data Quality Objective - This is the criteria against which the quality control data is compared.
