The Volusia County Health Department began collecting water samples from private drinking water wells in the DeLand Country Club Estates area after one well tested positive for dieldrin in early 2011.

In April of 2012, the health department conducted resampling of private drinking water wells that previously showed non-detects for the pesticide dieldrin.

Below you will see results from both tests. You will also find maps showing the results.

If you have a question about water testing, please contact Environmental Health Specialist Brian Volkman at
386-822-6250 x5082.

The Volusia County Health Department’s sampling strategy follows protocol from the Department of Health's Well Surveillance Program Technical Guide.

Hundreds of thousands of new babies are born in Florida each year, but what many Floridians do not realize is that each one of those babies receives special testing within their first 48 hours of life called Newborn Screening.

And those screenings are all done by the Florida Department of Health's laboratory in Jacksonville. Stefany Strong takes us on a road trip up to the state lab to show you what services they offer to protect your health.
