Since the bottle doesn't show anything informative as to whats in the water, i googled poland spring and sure enough they have their own website. Here are the numbers...

All units in (mg/l) or Part per Million (PPM)
Report date: September 2004
Testing period: 1st quarter 2004 - 2nd quarter 2004
Level Found - The highest level of each subtance detected at or above the MRL in representative finished product samples.
MCL - Maximum Contaminant Level. The highest level of a subtance allowed by law in drinking water (bottled or tap water). The MCLs shown are the federal MCLs set by the US Environmental Protection Agency and the Food and Drug Administration, unless no federal MCL exists.
MFL - Million Fibers per Liter.
MRL - Minimum Reporting Limit. Where available, MRLs reflect the Method Detection Limits (MDLs) set by the US Environmental Protection Agency or the Detection Limits for Purposes of Reporting (DLRs) set by the California Department of Health Services. These values are set by the agencies to reflect the lowest concentration of each subtance that can be accurately quantified by applicable testing methods, and are also the minimum reporting thresolds applicable to the Consumer Confidence Reports produced by tap water suppliers.
ND - Not detected at or above the MRL.
ppb - Parts Per Billion. Equivalent to micrograms per liter(μg/l).
NR - Not listed in State or Federal drinking water regulations.
NA - Not applicable to specific test method or test parameter.
Simply put, yes or no?
