Data quality: Data results are best available and comply with all documented methods
Data format for each parameter: Data qualifier text field and may contain a "less than" symbol, "greater than" symbol or blank cell. Data numerical value
Monitoring site ID: A 13 character ID code unique for each DSITIA monitoring site
