What is the safe radon-in-water limit in Concord, MA?

MassDEP guidelines recommend remediation for private well water radon levels exceeding 10,000 pCi/L, while many home inspectors and health officials advise treatment above 2,000–5,000 pCi/L. We install diffuse bubble aeration systems that eliminate 95% to 99% of radon gas before it reaches the home.

How do you remove arsenic from Concord well water?

Depending on whether the arsenic is Arsenic III (arsenite) or Arsenic V (arsenate), we deploy selective adsorption media (titanium dioxide or granular ferric oxide) or an oxidation-filtration train that binds arsenic and backwashes it safely to waste.

Can you drill in sensitive or historic areas of Concord without tearing up the lawn?

Yes. Ogden Wells operates compact, track-mounted rotary rigs and protective heavy-duty ground mats that minimize lawn disturbance and navigate narrow historic estate driveways.

Does the Concord Board of Health test for PFAS in private wells?

Concord strongly encourages private well owners to test for PFAS-6 compounds. We provide certified sample collection and install NSF-certified Point-of-Entry granular activated carbon (GAC) systems that absorb PFAS to non-detect levels.

Concord Geological & Well Profile

Hydrogeological data based on over 40 years of Ogden Wells drilling logs in Concord.

📐

Average Drilling Depth

300 – 600 ft

Solid bedrock fracture depth required to reach sustained residential yield.

💧

Typical Flow Yield

3 – 12 GPM

Gallons per minute. Low-yield zones can be restored with 3,000 PSI hydrofracturing.

🛡️

Steel Casing Sealed

50 – 90 ft

6-inch ASTM A53 heavy-wall casing seated with drive shoe into solid ledge.

🏛️

Septic Setback Distance

100 ft min.

Mandatory health separation from Title 5 septic tanks and leaching fields.

Bedrock Geology: Nashoba Terrane & Assabet Quartz Diorite

Concord geology features dense metamorphic gneisses interspersed with glacial lake deposits along the Sudbury and Assabet river valleys. Deep fracture flow often carries elevated radon and trace arsenic requiring precision treatment.

Rock Formations Encountered: Biotite gneiss, amphibolite, and intrusive quartz diorite

Common Water Quality Chemistry

•Waterborne Radon (5,000–18,000 pCi/L)
•Naturally occurring Arsenic (exceeding 10 ppb)
•Low pH (acidic etching of copper plumbing)
•Manganese aesthetic limits
