1. Drinking water visualisation
WISE workshop
12th of December 2011 BX

2. IDEAS
(First) ideas as a start for the discussion and decision making process (16th July 2008)

3. The art of simplifying
Not all info stored in WISE needs to be made visible. We have to answer the question:
What needs to be viewed by whom, when and why.
What is interesting for:
EC/national/local authorities
Scientists
Public

4. Questions to answer What to visualise For whom (target audience) How:
Level of visualisation (geographic detail)
Which information (scientific detail)

5. What to visualise Drinking water quality in EU MS First question:
Large WSZs > 5000 people ( WSZs)
Small WSZs people
Both small and large WSZs
Answer:

6. Target audience: general public and professionals
General public Professional
Geographic detail Scientific detail

7. Geographic detail Question two: which geographic detail? Answer:
European level
Member State level
(Region/Federation/Province)
Water Supply Zone level
(Future: estate/street level)
Answer:
Note the answer to question 2 will relate to the level of scientific detail

8. Scientific detail (1) Question three: Which information Answer:
Information on compliance and non-compliance
Which parameters:
A microbiology (compliance/non-compliance)
B chemical (compliance/non-compliance)
C indicator (alternative for (non)compliance)
All parameters or key parameters and which to select that are of EU relevance
Answer:
Note to question 3: C parameters are very important for the trust and confidence of the consumer

9. Scientific detail (2)
Click through possibility for more detailed information on:
Non-compliant/problem parameters
Values found
General information on the parameter and the relevance of the non-compliance/health implications

10. Scientific detail (3) In the case of non-compliance
Action plans to restore (A+B parameters) the quality
Action plans to improve (C parameters) the quality
Time frames/schedule
Progress to date
Trends in quality

11. Issues to address Question 4: Question 5:
How to indicate non-compliance due to domestic installations
Question 5:
How to distinguish between no information due to irrelevance of the parameter and due to non-compliance with monitoring requirements

12. Issues to address (2) Question 6: Question 7: Question 8:
Make a direct link with national websites/ databases
National contacts and national legislation
Additional and stricter standards
Types of water exempted etc etc
Question 7:
How to visualise population affected by non-compliance
Question 8:
Visualisation of derogations in place

13. Visualisation in the future
All WSZs in EU MS are compliant unless ……
Map of EUMS is green except for some “hot spots” indicated on the map where remedial action is ongoing/planned
Information on remedial actions, time frames, progress and trends
Information on relevance of n.c. parameters
(Health impacts/epidemiological information)

14. Possible ways forward
Ideas for combination of tabular and pie-chart presentations at various geographic levels
Example of the visualisation EMPACT used in Tucson, Arizona

15. EXAMPLES OF GRAPHICAL PRESENTATION AT EC/MS LEVEL
AGGREGATED NATIONAL DATA ON THE MAP OF EUROPE
AGGREGATED REGIONAL DATA ON THE NATIONAL MAP OF THE MS
DATA AT WSZ LEVEL ON DETAILED MAPS OF THE MS

16. Graphic presentation based on three levels
Level 1: EU with aggregated data for each MS
Level 2: MS with aggregated level for a number of WSZ (provinces, departements, river basins, counties …)
Level 3: WSZ with aggregated data on all samples taken in that WSZ

17. Level 1: EU
Aggregated data for each MS

18. At EU level This is a combination of tabular and graphic format
The map of the EU shows the MS
The user can click on a national summary for each MS: tabular option or
The user can use a scroll down menu for three graphic options to visualise aggregated info at MS level as pie-charts:
Microbiological quality (A parameters)
Chemical quality (B parameters)
Indicator parameters (C parameters)

19. At EU level: national summaries
The user can click on the option national summary and a table will pop-up for that MS
National level for each MS:
Tabular format
Select parameters that cause more than x% non-compliance annually
(x could be 1%, 5%, 10%)

20. Visualisation in pie-charts
Microbiological parameters
Chemical parameters
Indicator parameters

21. Colour coding for visualisation
> 95% compliance Green (including non-relevant parameters that do not need to be monitored)
> 90% compliance : Blue
> 75% compliance : Orange
< 75% non compliance : Red
No or insufficient information: Grey

22. Example microbiological parameters
Assume a MS with 100 WSZ > 5000 people
60 WSZ: both A parameters > 95% compliance
20 WSZ: both A parameters > 90% compliance
15 WSZ: both A parameters > 75% compliance
5 WSZ: one of the A parameters < 75% compliance

23. Example A parameters

24. Level 1: EU
Aggregated data for each MS
A parameters

25. Example B parameters Assume a MS with 100 WSZ > 5000 people
40 WSZ: All B parameters > 95% compliance
25 WSZ: All B parameters > 90% compliance
20 WSZ: All B parameters > 75% compliance
10 WSZ: one or more B parameters < 75% compliance
5 WSZ: insufficient information

26. Example B parameters

27. Level 2: MS Regions
Aggregated data for a Region in a MS: data aggregated for a number of WSZ
For the three parameter groups or selected key parameter e.g. Nitrate

28. Information at national and or regional level
Graphic information for individual WSZs or clusters of WSZs in regions
Using pie-charts with colour coding for the three groups of parameters (A, B and C)
Selection of key parameters

29. Trends in drinking water quality
Data are presented on an annual basis
Additional information could show trends for selected parameters

30. Selection of parameters
In the pie-charts select all or key parameters:
A parameters: Enterococci (add E.coli?)
B parameters: Arsenic, THM, Nitrate (add ….?)
C parameters: Coliform bacteria, CC22, Iron, Manganese, Aluminium, Sulphate (add….?)

31. At MS Regional level
Graphic presentation of key A, B, C parameters for the MS
Percentage of compliance in the WSZ in the Region for each key parameter in the MS

32. Example selected key parameter Nitrate:
Graphic presentation at Regional level:
Example of nitrate compliance in the various WSZs in a region of a Member State
Percentage of WSZ in this level with
>95-100% compliance with nitrate value DWD: green .
> 90% compliance with nitrate value DWD: blue
> 75% compliance with nitrate value DWD: orange
< 75% compliance with nitrate value DWD: red
Insufficient information on nitrate: grey

33. Level 3: WSZ
Aggregated data for each WSZ

34. Example selected key parameter:nitrate
Graphic presentation at WSZ level
Percentage of samples in the WSZ with
>95-100% compliance with nitrate value DWD: green .
> 90% compliance with nitrate value DWD: blue
> 75% compliance with nitrate value DWD: orange
< 75% compliance with nitrate value DWD: red
Insufficient information on nitrate: grey

35. Derogations Forms D1, D2, D3 of the Guidance Document
Information on derogations in force
At national level
Tabular information
Graphic information, based upon maps
At EU level
Graphic information based upon maps for selected parameters
Parameters most frequently derogated:
Arsenic, fluoride, nitrate, iron and pesticides (atrazine, desethylatrazine)

36. Tucson Water
is a department of the City of Tucson which operates as a public utility serving approximately 720,000 people.

37. What’s the Quality of Our Drinking Water?
And Why is it Important to You?

38. What is Tucson’s Water Quality?
22 On-line Water Quality Monitoring Stations

42. Nitrate as Nitrogen
Nitrate as Nitrogen can occur in drinking water supplies from both natural sources and human activities (such as fertilizer use, munitions manufacturing, and septic systems). The EPA's health-based limit for nitrate as nitrogen in drinking water is 10 mg/L - all of Tucson's water supplies have nitrate as nitrogen levels below this limit. For more information on water quality, see our Terms and Definitions page.
