A compact view of the available monitoring results. Choose all sites or an individual sampling site, then switch between the latest survey and the project average.
Compare the two most recent available survey dates for each indicator. FreshWater Watch and additional water-quality tests are compared separately when their sampling dates differ.
Review whether positive 48-hour LaMotte coliform screening results are isolated or recurring. Same-site results recorded on the same calendar date are counted once so duplicate CSV rows do not inflate recurrence.
Identify sampling sites that may be falling behind their usual monitoring pattern. The expected interval is based on each site's own survey history, with the project-wide typical interval used when a site has limited history.
A compact view of when each monitoring location has been sampled. The numbers show sampling visits, not water-quality status.
The sample date is shown below each monthly frequency cell. Where consecutive samples are available, the small number between cells shows the number of days between samples. Hover or focus a cell for the full survey date details. Days since last sample are calculated from each site's most recent sample date to today's date. When more than 12 months of data are available, the timeline shows the latest 12 months.
Compare the latest recorded result from each sampling site.
Nitrate and phosphate bars use the midpoint of the FreshWater Watch result range; the original result band is shown beside each site. Turbidity uses the recorded NTU value.
Compare how stable each sampling site's results have been across repeated surveys. Consistency describes variation only; it does not mean that a consistently high result is environmentally desirable.
Assess whether repeated survey results are generally improving, stable or deteriorating over time. The analysis uses the overall direction of the available series rather than relying only on the first and latest result.
Shows the direction of results by survey date for the whole project or for an individual sampling site. Choose All sites for the project view, or select a site for its own trend.
View recorded pH results against a fixed pH scale, using pH 7 as the neutral reference point. Values below 7 are acidic and values above 7 are alkaline. The summary also shows how far the latest result is from neutral.
Explore observed patterns by calendar month or season. Values are averages of the available samples in each period.
Explore whether two FreshWater Watch indicators appear to move together. Each point represents one sample where both selected indicators were recorded.
