Getting Started with Lead Watch
What is Lead Watch
Lead Watch is a web-based tool with which to display, in the form of a dashboard, sites and sample data at the country level where drinking water may contain lead contaminant levels above World Health Organization (WHO) guidelines.
Lead Watch Dashboard
The Lead Watch dashboard consists of three areas. The country display Map, dashboard data, and a pivot table.
- Country Map.
This displays a map of a selected country with the location of sites where samples were taken as color coded points on the map. Each color code represents a specific contaminant level. With red being worst and green being the least in that a greater number of the samples taken are within WHO guidelines.
- Dashboard Data.
This will display, for a selected country, the total number of all samples taken, the percentage of these samples that are above WHO guidelines and the average and median lead concentrations in all samples taken.
- Pivot Table.
This lists all the sites sampled within the country and the percentage of samples taken at that site that are above WHO guidelines, the average or mean and median concentration of contaminants in all samples taken at the site.
Country Map/Data Selection
To see data and a map for a specific country, select the country from the drop-down menu at the top of the page. Lead Watch will display a map highlighted by color coded points denoting the location of the samples taken.
These points are color coded ...
| Color | WHO Guideline Level |
|---|---|
| Red | More than 75% of samples with lead contaminant levels higher than WHO guidelines. |
| Amber | Between 50 and 75% of samples with lead contaminant levels higher than WHO guidelines. |
| Blue | Between 25 and 50% of samples with lead contaminant levels higher than WHO guidelines. |
| Green | Less than 25% of samples with lead contaminant levels higher than WHO guidelines. |
You can use the tools on the map to zoom into specific areas or locations.
Your country selection will also highlight the total number of samples taken, the percentage of samples, of alll samples taken, above WHO guidelines and the average and median lead concentrations for all samples.
A pivot table will be displayed: This will list all the sites sampled within the selected country as well as the percentage of samples taken at the site above WHO Guidelines, the average concentration of lead contaminants in the samples taken and the median concentration of contaminants in the samples.
Stratifying by Source Type
The pivot table will also contain a drop-down menu containing all the selected country’s water source types (i.e. Rainfall, Pipe, etc.,) from the uploaded data, for you to stratify the table by source type.
Selecting a source will display table data for all sites with the same water source type.
