Dear All, are you aware of publications/articles in which the different discharge limits of treated wastewater are compared by country, perhaps also as regards the regulatory measures implemented and the relative monitoring values to achieve them, such as environmental/wastewater taxes with incentive, compensation functions or others ?
Thanks for exchanging views in advance, it would be enough even for your own country.
