In Rhode Island and Massachusetts, water quality can vary dramatically between city and rural homes — especially in areas relying on well water. Even municipal systems, which test water before it reaches your home, can’t detect what happens in your pipes. If your water smells strange, tastes metallic, leaves residue, or causes dry skin and hair, it may be time for a professional test. Knowing what’s in your water is the first step to protecting your health and home.

What is Water Quality Testing?
Water quality testing is a quick, non-invasive process that checks for a wide range of potential contaminants and imbalances. During your test, a technician collects a small water sample from your tap or well and performs and on-site or lab-based analysis.
Typical testing checks for:
- Hardness (calcium and magnesium levels)
- pH balance
- Iron, sulfur, and manganese
- Lead or copper (especially in older plumbing)
- Chlorine or chloramine (in city water)
- Total dissolved solids (TDS)
- Bacteria (such as coliform or E. coli, in wells)
Most results are available within 24 to 48 hours, and some tests can even be completed on-site during your appointment.
Do I Need Water Quality Testing?
Many homeowners in Rhode Island and Massachusetts don’t realize how much their water quality can impact their health, plumbing, and appliances. You should schedule a water test if:
- You rely on well water and haven’t tested in the last year
- You use city water and haven’t tested in 3+ years
- You notice a strange taste, smell, or discoloration
- Your water leaves white spots, orange stains, or buildup
- Family members have sensitive skin or health conditions
- You recently purchased or renovated a home with old plumbing
Even homes on public water systems can experience contamination due to aging pipes or outdated fixtures inside the home.
Water Treatment Options to Consider
Once your water has been tested, you’ll receive a full report and expert recommendations. Depending on what we find, you may benefit from:
- Water softeners: Reduce hardness to protect pipes and improve the “feel” of your water
- Reverse osmosis systems: Filter out lead, nitrates, and other dissolved solids
- Carbon filters: Remove chlorine, bad odors, and improve taste
- Acid neutralizers: Correct low pH that causes corrosion and metal leaching
- UV purifiers: Kill bacteria and viruses in well water
Even if your water is technically “safe,” treatment can significantly improve quality of life and help extend the life of your plumbing, water heater, and appliances.
