1. Records with no value are not included in statistical calculations.
2. Values lower than the minimum detection limit are assumed to be 0.
3. Average pH is not calculated as a mean of pH values, but rather a mean of hydronium ion concentration.
4. Dissolved metals used for calculated acidity values when available. Acidities calculated from total metals may be exaggerated.

2. Values lower than the minimum detection limit are assumed to be 0.
3. Average pH is not calculated as a mean of pH values, but rather a mean of hydronium ion concentration.
4. Dissolved metals used for calculated acidity values when available. Acidities calculated from total metals may be exaggerated.

1. Records with no value are not included in statistical calculations.
2. Values lower than the minimum detection limit are assumed to be 0.
3. Average pH is not calculated as a mean of pH values, but rather a mean of hydronium ion concentration.
4. Dissolved metals used for calculated acidity values when available. Acidities calculated from total metals may be exaggerated.
