comments:
- The site coding is not fixed, thus the number of digits is variable ("0" is not true).
- Sampling sites: 32 for rivers; 11 for groundwaters; 7 for wetlands (lakes); 29 for transitional and coastal waters.
This does not mean that there are 79 fixed stations. Some stations have e.g. samples for water and sediment, but others for fish or macroalgae, etc.
