Hi,<br /><br />For my research I am defining groundwater quality of different cities. I find that in the database only a difference is being made between samples with 'good chemical status' and 'poor chemical status'. There are only two absolutes. Where can I find the requirements for when a sample if defined as a good sample (or even a bad sample)?<br />Also, where can I find where the samples are taken?<br /><br />Kind regards,<br /><br />Auke Tempel<br />
