Temperature: Degrees Celsius (°C) can be converted to degrees Fahrenheit (°F) by using the formula °F = [1.8(°C)]+32. Degrees Fahrenheit can be converted to degrees Celsius by using the formula °C = 0.556(°F-32).

Sea level: In this report, "sea level" refers to the National Geodetic Vertical Datum of 1929 (NGVD of 1929, formerly called "Sea-Level Datum of 1929"), which is derived from a general adjustment of the first-order leveling networks of the United States and Canada.

Abbreviated Water Quality Units:

L (liter) mg/L (milligram per liter)
µg/g (microgram per gram ng/g) ng/g (nanogram per gram)
µg/L (microgram per liter) ng/L (nanogram per liter)
µS/cm (microsiemens per centimeter at 25° C) pCi/L (picocurie per liter)
