Barrier to well water testing | Recommendation to overcome barrier | Study |
---|---|---|
Inconvenience in dropping off and picking up water sampling bottles (time to get to water test locations and hours of operation for water testing centres) | Making bottle pick up and drop off more convenient for water testing or setting up services for delivering and picking up water sampling bottles | |
No need to frequently conduct testing | Sending well testing reminders and making the issue of well water testing more salient to well water owners | |
Lack of information or misinformation on water testing | Educational/information awareness programs | |
Forgetfulness of procrastination | Sending reminders | |
No stated reason | Educational/information awareness programs | |
Costs | Provide cost sharing or incentives | |
No health problems attributed to well water testing or no problem perception | Provide educational/information awareness programs | |
Use of water treatment | Education/information awareness on what treatments to use | |
Interpretation of water quality result | Education/information awareness on what exceedances to MAC’s mean |
