🚨 Forever Chemicals - What’s Really in Your Water? 🚨

PFAS, PFOAs & Microplastics have been detected in both city and well water across the country. These contaminants are often called “forever chemicals” because they can remain in the environment—and in our bodies—for years.

Research has linked exposure to PFAS and related compounds to serious health concerns, including certain cancers, birth defects, hormone disruption, immune system effects, and liver and kidney damage.

The good news? You have options.

🚨 MARYLAND IS CURRENTLY IN A DROUGHT — IS YOUR HOME PREPARED? 🚨

Did you know much of Maryland is currently experiencing drought conditions?

Whether you're on city water or a private well, prolonged dry weather can impact your water supply, water quality, landscaping, and even your home's plumbing system.

💧 Homeowners should:
✔ Check for hidden leaks
✔ Water wisely and only when needed
✔ Watch for changes in well water pressure or flow
✔ Stay informed about local water restrictions
✔ Consider having your water tested if you notice changes in taste, odor, or appearance

For well owners, drought conditions can sometimes lead to lower well yields, sediment issues, and changes in water quality. Don't wait until you run out of water to take action.
