MEDIM Medium codes and the descriptions are:
0 = Not determined
6 = Ground water (Water below the surface of the earth contained in the saturated zone. The code does not include soil moisture or interstitial water.)
9 = Surface water (Water on the surface of the earth stored or transported in rivers, streams, estuaries, lakes, ponds, swamps, glaciers or other aquatic areas. This code also may refer to water in urban drains and storm-sewer systems.)
SAMPL Sample record number
Database record number individual to site, date, and time of sample collection.
Station_Nm Station Name
The station name for ground-water sites is the same as the local number. The local number for ground-water sites includes the township and range followed by the section and a series of letters that designate the quarter-section subdivisions, from the largest to the smallest, followed by a site sequence number. The order of the quarter-section subdivisions differ from that used by the Bureau of Land Management and the public-land survey. The public-land survey uses a series of coordinate directions and a fraction to designate the quarter-section subdivisions listed from smallest to largest followed by the section, township, and range. For example, the same 10-acre plot would be described by using the public-land survey as NW1/4 SW1/4 NE1/4 Sec.5 T2S R3E and described by using the USGS Local_No as 02S-03E-05 ACB. A direct comparison between the quarter-section subdivisions for the public-land survey and the USGS Local_No is that A=NE, B=NW, C=SW, and D=SE.
Site_ID Site Identification Number
The Site ID for ground-water sites is a 15-digit identification number assigned to the site, and contains no blanks or alphabetic characters. Although the site-identification number is formed initially from the latitude and longitude of a point believed to represent the location of the site followed by a 2-digit sequence number, the Site ID is an identifier and not a locator. The first six digits of the Site ID are the value of latitude, the 7th through 13th digits are the value of longitude, and the 14th and 15th digits are sequence numbers used to distinguish between sites at the same location.
STYPE Sample type codes and the descriptions are:
A = Not determined
B = Other QA
H = Composite
1 = Spike
2 = Blank
3 = Reference
4 = Blind
5 = Duplicate
6 = Reference Material
7 = Replicate
8 = Spike solution
9 = Regular
Each parameter code for the following parameter code attributes is preceded by a remark code for that parameter. Example: R00028 is the remark code field for P00028. Remark codes and the descriptions are:
< = Less than. (Actual value is known to be less than the value shown.)
= Greater than. (Actual value is known to be greater than the value shown.)
E = Estimated value. (Value is estimated.)
A = Average value. (Value is an average.)
V = Contamination. (Constituent was detected in both the environmental sample and the associated blanks.)
S = Most probable value.
