Advances in remote sensing are making continuous water quality monitoring much easier. At our company we use a combination of satellite imagery and in situ optical sensors to monitor rivers and reservoirs. As well as a general water quality index, we can estimate concentrations of harmful nutrients, chlorophyll-a, phycocyanin, suspended matter, dissolved organic carbon to name a few.
A further advantage of satellite remote sensing for water quality is that it can be done by a neutral third party, without permission or access to the land, which can help bring a bit of objectivity to the politicized narrative around water quality we are seeing at the moment.

- lukezeitlin 2y agoConsiderably more affordable than the alternatives: - multiparameter sondes (submersible sensors): More expensive, maintenance heavy, only measure at one point. - Manual grab-samples: Again more expensive when you factor in labour, unreliable, single point. Remote sensing has its disadvantages though; cloud cover can be problematic for example.
