There's no federal law requiring a specific well cap. Every state writes its own rules. That's why a driller who works in three states might need three different cap setups on the truck. The EPA regulates public water systems under the Safe Drinking Water Act, but private wells? Those fall...

A delivery truck backs over your wellhead. The PVC casing cracks six inches below grade. Now you’re looking at a $3,000 well repair instead of a $200 protector you should have installed last year. This happens more often than most property owners realize. Wells in driveways get clipped by snowplows....

You are standing in a gas station parking lot in New Jersey. The Phase II ESA came back hot — benzene in the shallow groundwater, no surprise given the site history. Now your client needs three monitoring wells installed flush with the asphalt, and every single one has to survive...

You need to pull a representative air sample from the well headspace without breaking the seal, without removing the cap, and without compromising the data integrity your lab and your regulator...

A monitoring well on a construction site in New Jersey. No lock on the cap. Somebody drops a cigarette butt in. Now your next round of groundwater samples is compromised and your client is explaining the anomaly to the DEP. It sounds like a worst-case scenario, but we hear versions...
