Water Chemistry Monitoring Workshops
These sessions are designed to inform citizens of the program's goals and how to monitor and
evaluate physical and chemical features of water. Six water quality
parameters, measured with a customized test kit, form the core of the
citizen data. The basic monitoring |

Citizens who monitor lakes or deeper waterbodies often use a Secchi disk
to determine the degree of visibility in natural waters. The 20 cm
diameter disk is weighted and has a line that is marked every tenth meter. To collect
samples from deeper waterbodies, monitors can use a Remote Sampler.
This sampler can also be used to conduct depth profiles in a lake, up to 10
ft. deep. Citizens who monitor brackish and/or marine waters
on the coast also measure salinity with a Hydrometer.
