Is there financial help if I can鈥檛 afford testing and treatment?

Please refer to the Financial Help page for current information.

How long does it take to get my results?

Bacteria results are usually ready within 48 hours. Allow plenty of time for other tests. They can take 2鈥4 weeks.

I am buying/selling a home or representing a buyer/seller. What should I consider?

The wellhead should be in good condition and up to modern standards.

Was the well ever tested? Do you know what it was tested for? Was it tested by a certified drinking water laboratory? Most free test kits do not check for chemicals that can affect your health. Without a complete test by a certified laboratory, you may be drinking water with contaminants that you cannot see, taste or smell.

Allow 4鈥5 weeks minimum for testing. A private lab may be able to shorten this time, and you may be able to pay extra for a 鈥渞ush鈥 on tests done by 小黄鸭视频 County, but some of these tests take a certain amount of time to complete.
