ND: This contaminant was not detected at or above our lower reporting limit (LRL)[cite: 2].

Standard: Indicates Maximum Contaminant Level (MCL) for EPA Primary Standards or guideline values for EPA Secondary Standards[cite: 2].

LRL: Lower Reporting Limit (lowest level that the laboratory can detect)[cite: 2].

R2 Qualifier: The laboratory is not licensed for this parameter; reported result cannot be used for compliance purposes[cite: 2].

Hold Time Note: pH analysis has a 15-minute hold time from sampling. Chlorine, Chloramine, and Chlorine Dioxide hold times are immediate; results should be considered an estimate[cite: 2].

ND: Indicates that none of this analyte has been detected at or above the specified detection level[cite: 1].

MCL: Maximum Contaminant Level as established by US FDA for bottled water[cite: 1].

RL: Laboratory reporting limit for method[cite: 1].

Units: Results are reported in mg/L unless otherwise noted[cite: 1].

Note 2: Fluoride MCL is determined by annual average of maximum daily air temperatures where bottled water is sold (21 CFR 165). The MCL for bottled water with added Fluoride is 0.7 mg/L[cite: 1].

Note 3: Mineral water is exempt from allowable levels per 21 CFR 165.110(b)(3) and (4) for aesthetically based allowable levels[cite: 1].

Note 4: MCL established by US FDA for waters that meet "Purified" definition is 5-7 pH Units (USP XXIII Standards, 21 CFR 165)[cite: 1].

Note 5: Bottled water shall not contain beta particle and photon radioactivity in excess of an annual dose equivalent to 4 millirems/year (=50 pCi/L)[cite: 1].
