Deployed turbidity sensors- especially in stormwater scenarios

[Emily Resseger]

We are looking at installing a few turbidity sensors in stormwater pipes upstream and downstream of a BMP in the next year, with the goal of exploring using regressions and discharge to calculate TSS loads. 

Does anyone have a turbidity sensor deployed long-term that they have had good luck with? I found a somewhat recent paper from USGS comparing five installed sensors: https://pubs.usgs.gov/of/2020/1123/ofr20201123.pdf. This helped me feel better about the InSitu Troll I am leaning towards, but that is a lot of instrument for just one sensor.

Hi Emily,

I have used both EXO and InSitu turbidity sensors and both have worked well for me. I will say that in the eutrophic system that I used the EXO in we had to clean the turbidity sensor (EXO) every two weeks during the summer, despite the wiper. The InSitu is great because, for example, it requires very small amounts of calibration standard, which is very expensive. I think regardless of your choice, you should expect to need to clean the sensors regularly in the growing season. Sorry if this is more basic than you needed, just wanted to be complete.
