There are three main tests:
Ecoli/Coliform Test
This test is highly recommended for anyone with well water. This test will test for harmful bacteria in the water supply that would cause you to become sick.
Lead Water Test
This test is highly recommended for houses built prior to 1978. Lead pipes and lead solder were used in construction during this period which can cause lead contamination in your water, even if you have municipal water.
Nitrate/nitrite Test
This test is highly recommended for homes in rural areas that are near farmland and have a well for drinking water. This test will find if there is contamination from fertilizer and pesticides that farmer’s use on their fields.
Other water testing is available as well.
I take a water sample to a Water Testing Lab for analysis and you will receive their report when it is ready. This lab can perform many other kinds of water tests upon request.
