Measured by the EPA · Talbot County, MD
Talbot County, MD tap water is fully legal.
It is also 11× the health standard for lead.
Talbot County is on groundwater — wells rather than a river intake — serving roughly 17,357 people through 7,185 connections. That is unusual for this area, where most supplies come off the Potomac, and it changes which contaminants are worth worrying about.
Groundwater does not carry the chlorination byproducts that dominate river supplies, because it needs far less disinfection. What it carries instead comes out of the rock: arsenic, radium, manganese, and nitrate where there is farming above the aquifer. Boiling concentrates all of them rather than removing them.
Every federal limit that applies here is met. Those limits weigh what removal costs. EWG says its health standards are “based only on protecting health and does not consider technical feasibility or the cost of water treatment”. Here is how far apart the two are.
Harm to the brain and nervous system · EPA limit 10 ppb (action level, lowered from 15 ppb, in force November 2027)
It was tested for 29 PFAS compounds in the EPA's latest round and none came back above reporting limits — genuinely good news, and a single window in time. Lead sampling put the ninetieth percentile at 2.1 ppb — meaning nine in ten homes tested below that, and one in ten above it.

How this water is treated before it reaches you
Treatment makes water safe to distribute. It is not designed to remove PFAS, and chlorine-based disinfection creates byproducts of its own.
Levels: EPA Fifth Unregulated Contaminant Monitoring Rule (UCMR5, 2023–2025) for PFAS, and the Lead and Copper Rule 90th-percentile result for lead and copper — the highest reported for Easton Utilities. Health standards: EWG's published drinking water standards, updated February 2025. Levels vary by sampling point and date, and being above a health standard is not a legal violation.
5 contaminants above EWG's health guidelines
Everything EWG found above its guideline in Talbot County's water, from testing in 2014-2023. A level can be under the legal limit and still be listed here: EWG's guidelines are set to protect health, not to be easy to meet.

Talbot County water quality FAQ
Is Talbot County, MD tap water safe to drink?
Public water in Talbot County meets federal EPA legal limits. But "legal" is not the same as "clean": across the Coastal-plain aquifers, independent testing routinely finds contaminants like arsenic (naturally occurring) and radium & radionuclides (naturally occurring) above EWG's stricter health guidelines. Enter your zip code above to see your exact utility's record.
What contaminants are common in Talbot County water?
For the Coastal-plain aquifers, the contaminants that most often exceed health guidelines are arsenic (naturally occurring), radium & radionuclides (naturally occurring), nitrates (agricultural runoff), PFAS (forever chemicals) and total trihalomethanes (where chlorinated). Your specific levels depend on your utility, which you can look up by zip code above.
Does Sanavia install reverse osmosis systems in Talbot County?
Yes. Talbot County is roughly 51 miles from our Arlington base and inside our service area. A Sanavia Hydra reverse osmosis system installs under your sink and reduces every contaminant class above, and we'll mail you a free water test kit.
Where does Talbot County tap water come from?
Talbot County's primary public water system is Easton Utilities, which serves roughly 17,400 people. It sits in the Coastal-plain aquifers, so its water shares that region's contaminant profile. Larger areas may have more than one utility, so enter your exact zip code above for your own system's EPA record.
Is well water in Talbot County tested for these contaminants?
No. Private wells are not covered by municipal testing, so the responsibility falls on the homeowner. If your Talbot County home is on a well, nitrate and naturally occurring contaminants are worth testing for specifically, and a reverse osmosis system reduces them at the tap. We'll mail you a free water test kit either way.

Reverse osmosis in Easton & Talbot County, MD
Easton Utilities treats this water to the federal standard, yet the contaminants listed above still exceed EWG’s stricter health guidelines — Arsenic (naturally occurring), Radium & radionuclides (naturally occurring), Nitrates (agricultural runoff) and 2 more. Most of them either pass straight through treatment or form after the plant, in the pipes between it and the tap, which is why the fix has to be at the tap as well.
PFAS is the reason a carbon pitcher is not enough here. The compounds do not break down, they are measured in parts per trillion, and the federal limit that covers them is not enforceable until 2029. A reverse osmosis membrane is one of the few things at household scale that reduces them rather than passing them through.
