Appendix 3: Information that should be recorded regarding each Sampling Site
Certain information should be recorded regarding each sampling location in order to facilitate interpretation of groundwater quality data within an SOE programme. Much of this data relates to the ownership, location, surrounding land use and the physical construction of the bore. It is advisable to use a database to store all of this information. Several regional councils in New Zealand use the 'WELLS' database originally constructed by Environment Canterbury. A screen shot of site information from this database is provided below. Note that some of the information about the site should be taken into the field on each sampling event, to ensure the site can be positively identified before sampling (see Step 1 and Appendix 2).
Information that should be recorded regarding each sampling location:
- Site number
- Site name
- Site location
- Easting
- Northing
- Accuracy of easting and northing (eg, ±10 m)
- Owner/occupier details
- Sample site location information
- Sampling instructions
- Land use within 10 metres
- Land use within 100 metres
- Land use within 500 metres
- Bore/water use
- Details of well head protection
- Well construction details
- Depth of screened/source interval
- Source aquifer
- Miscellaneous notes
