The Wisconsin Well Testing Access Program (WellTAP) Toolkit includes informational resources and customizable outreach tools to help local and tribal health departments (LTHDs) understand, access, and share the program.
Program overview
WellTAP is an expansion and rebranding of DHS' fee-exempt private well testing program. The goal of WellTAP is to provide private well testing for at risk groups that are unable to do so themselves.
WellTAP provides no cost testing to private well users where their primary well serves a key target group and a financial, mental, or other burden prevents them from testing on their own. The key target groups include people who are pregnant, children 12 and under, and people who are immunocompromised.
Examples of people who are immunocompromised include those undergoing active cancer treatments, people taking immunosuppressive therapy due to an organ or bone marrow transplant, or those that are being treated with biologic therapies that affect the immune system. People who have cancer, an autoimmune disease (such as Type 1 diabetes, rheumatoid arthritis, or lupus), have advanced or untreated HIV, or are over the age of 65 can also be immunocompromised.
Informational resources
- Program Guide, P-03666 (PDF): Overview document for LTHD staff describing what the program is, who qualifies, and how the sampling works.
- Acute Detections Response Guide (Word): Supporting document that provides LTHD staff template language to use when sharing the results of acute health hazards (bacteria, nitrate, or manganese) with well users.
- Drinking Water Health Advisory Letter Templates (Word): Supporting document that provides language to use that provides the well user information on any substances detected above health thresholds and actions they can take to reduce exposure.
Customizable outreach tools
- Template Outreach and Advertising Materials (Word): This resource contains a message map laying out the main elements of the program as well as template newspaper and radio language, webpage content, and social media posts.
- Template Fact Sheets–These templates highlight what the program is, who is eligible, and contains room for the LTHD’s contact information and branding.
- The portrait fact sheet is now available in multiple languages:
- The landscape fact sheet is now available in multiple languages:
Faster return shipping
With the rollout of WellTAP program, the Wisconsin State Laboratory of Hygiene (WSLH) has been taking steps to improve the delivery times of fee-exempt samples.
- WSLH is setting up a program with UPS and FedEx to provide WellTAP participants with pre-paid shipping labels.
- This program will allow for next-day delivery of samples for all UPS shipments and most FedEx shipments.
- WLSH will be reaching out to LTHDs with more information shortly.
- For questions in the interim, contact Marty Collins (WSLH) at Martin.Collins@slh.wisc.edu.
Resources for public water users include contaminant-specific fact sheets, a lead in drinking water poster for display, and action guides with steps on how users can protect themselves from specific contaminants.
