We recommend testing if you notice a chemical/fuel smell in your water, if there has been a spill nearby, or if you live near high-risk sites (gas stations, landfills, factories).
Not always. Standard water softeners do not remove chemicals. Activated Carbon and Reverse Osmosis are effective against many VOCs, but we need to identify the contaminant first to recommend the right filter.
THMs are chemical by-products that can form when chlorine reacts with organic matter. If you are on a chlorinated cistern system, this is a critical test.
No. Standard home inspections usually only check for bacteria (E. coli). Chemical testing is a specialized add-on that smart buyers request for older or rural properties.
