Drinking Water Interpretations
Summary: Your water was acceptable for all items tested on this sample report. Details are presented below:
Constituent Result Units MCL Result Compared to MCL
Inorganic - Primary Less Than or Equal Exceeded
Nitrate Nitrogen ND mg/L 10 PASS
ND=Non-Detect
Definitions
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 under the following searches:
Water Purification & Filtration Equipment
Water Softening & Conditioning Equipment
Water Treatment Equipment

Definition
Blank :Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples.
DQO :Data Quality Objective - This is the criteria against which the quality control data is compared.
LCS :Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery.
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 analyted. 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.
