Parameters
Parameter codes are 5-digit codes used to identify the constituent measured and the units of measure. Some parameter code definitions include information about the methods used to measure the constituent, but this level of information is not currently consistent in the naming system.
There are two types of parameter codes:
Fixed-value codes
The result value is a numeric code that represents a textual meaning. [ Tab-separated -- saved to file || Tab-separated -- display to screen || HTML ]
Numeric codes
The result is a numeric value for chemical, physical, and biological data.
The following table shows an example of several parameter codes and definitions. This table also illustrates how several parameter codes may exist for one type of measurement.
| Parameter Code | Parameter Definition |
|---|---|
| 00910 | Calcium, water, unfiltered, milligrams per liter as calcium carbonate |
| 00915 | Calcium, water, filtered, milligrams per liter |
| 00916 | Calcium, water, unfiltered, recoverable, milligrams per liter |
| 91051 | Calcium, water, filtered, micrograms per liter |
