There have been relatively small changes over time in water quality monitoring sites.
We are currently at a point in our implementation of a risk-based approach such that we may actually make adjustments to water quality monitoring in accordance with the risk assessments we've done. We have made small changes in frequency monitoring. We've reinitiated different types of monitoring in parts of the country, based on our risk assessment.
It's very much a dynamic and adaptive system that we have at this point. We're making small changes over time as we go, as the data indicates that the changes are warranted.
