Supplemental Information: term definitions | general description of pH readings
|Sample Start Date
|| Start date of the sample collection period.
|Sample Stop Date
|| Stop date of the sample collection period.
|Total Precipitation - Rain Gauge (inches)
|| Total amount of precipitation measured during the sample collection period in inches.
|Total Precipitation - Sample Weight (grams)
|| Weight of the precipitation collected during the sample collection period.
|Field Conductance Reading (us/cm)
Conductance is a measure of the ability of water to conduct an
electrical current. It provides an indication of the amount of
dissolved material in the sample. Units are microsiemens per
|Field pH Reading
measures the scale of acidity of the water based on the hydrogen ion's
activity. The range goes from 0-14, with 7 being neutral. pH of less than 7 indicates acidity, whereas a pH of greater than 7 indicates a base. The natural background of rainwater in New England has a pH of approximately 5.0.
|Field pH Check Sample Reading
|| Quality Control Check Sample is used to verify the calibration of the pH Meter. The check sample should read 4.90 +/- 0.20 pH units.
|Precipitation Acidity Level
|| General description of the acidity level based on the field pH reading.
