Monitor Water Contaminant Parameters
Verified by Operations Schedule, On-going Data Report
One of the following requirements is met:
-
The water contaminants listed in this feature are monitored at intervals of no less than once per year and results are submitted annually through WELL Online. The number and location of sampling points complies with the requirements outlined in the Performance Verification Guidebook.
-
The levels of the water contaminants listed in this feature, as reported in a local municipal water quality report, are submitted annually through WELL Online.
-
Project achieves at least one point in Feature W05: Water Quality Consistency.
Note: For requirement a), projects are not required to use devices or methods that comply with the requirements described in the Performance Verification Guidebook. However, if measurements are undertaken by a WELL Performance Testing Agent in compliance with the Performance Verification Guidebook, results submitted to GBCI from each year and test location may be averaged and utilized for recertification purposes.
