The number reported may need to be rounded using EPA rounding rules to fit into the field. The rounding should maintain the greatest significance possible within the field length limitation. The records formats are intended to be general for a variety of media, but some special considerations apply to certain common media. All temperature fields are in centigrade. All times will be given on a 24 hour clock, known as military time.
All fields are alpha-numeric unless remarks state otherwise.
Consistency in station naming is crucial for GIS and modeling use of information. EPA designated names shall be used when they exist. If the data generator finds it necessary to change the format, notification of the exact nature of the differences should be discussed with an EPA representative and accompany the submission. Suggestions for improvement are welcomed. Data Record - All sample results and batch data for a particular batch and analyte should be together in the same subdirectory.
