Summary edit

Description

Chlorophyll count is one indicator of water quality we're looking for in each water sample from the bottom, middle and surface depths. We're also sampling for total phosphorus and total nitrogen.

All three indicators will tell us more about the quality of the water and the amount of nutrients that could be coming from rivers and runoff on land.
