Hello,
I am in search of available PDF/s or the likes that has water quality standards for surface and wastewater from the World Health Organization (WHO). You do find a lot available for drinking water for various chemicals, but it seems to me just hard to find also such data for wastewater and surface water. So, if anyone has them available as PDF/s or links be kind to add your answer here.
Thanks,
Danial B. Tahir
