The pH level tells you how acidic or basic your water is. The pH level of the water can change how your water looks and tastes. If the pH of your water is too low or too high, it could damage your pipes, cause heavy metals like lead to leak out of the pipes into the water and eventually make you sick. Other germs or harmful chemicals that you should test for will depend on where your well is located on your property, which state you live in and whether you live in an urban or rural area.
These tests could include testing for lead, arsenic, mercury, radium, atrazine and other pesticides. You should check with your local health or environmental department or the EPA to find out if any of these are a problem in your region. Please remember if your test results say there are germs or chemicals in your water, you should contact your local health or environmental department for help and test your water more often.
