What are the well setback requirements in Groton, MA?

Under the Nashoba Associated Boards of Health (NABH) regulations for Groton, private drinking water wells must maintain a minimum 100-foot separation from any septic tank, distribution box, or leaching field, 10 feet from property boundary lines, and 25 feet from public roadways.

How deep do water wells typically need to be in Groton?

Most residential bedrock wells in Groton range between 250 and 520 feet. In areas like Farmers Row and West Groton with tighter rock fractures, depths of 450 to 550 feet are common to secure sustainable yields of 5+ GPM.

Is water hydrofracturing common in Groton?

Yes. If a newly drilled or older existing well produces less than 2 GPM, our 3,000 PSI zone-isolation hydrofracturing equipment injects high-pressure potable water to flush silt and expand natural bedrock fracture networks, frequently doubling or tripling flow rates.

How fast can Ogden Wells respond to an emergency pump failure in Groton?

With our primary service operations centered in Tewksbury and mobile service rigs throughout Middlesex County, we provide same-day 24/7 emergency dispatch to Groton for total loss-of-water crises.

Bedrock Geology: Nashoba Formation & Ayer Granodiorite

Groundwater in Groton is held within crystalline bedrock fracture networks. Properties around Lost Lake and the Nashua River basin frequently encounter glacial till over consolidated bedrock, occasionally showing artesian hydrostatic head pressures.

Rock Formations Encountered: Foliated crystalline granite, quartz-diorite and high-grade schist

Common Water Quality Chemistry

•Radon gas in water (2,000–12,000 pCi/L)
•Iron & manganese mineral staining
•Naturally acidic pH (6.0–6.4)
•Hardness minerals from schist fractures
