Same day if it is urgent, otherwise within the same week. For urgent needs, you can count on us.

The laboratory does. We collect the samples, keep the chain of custody intact and deliver them. Laboratory fees are paid to the laboratory and are separate from our charge.

What does the sampling service cost?

Consultation and service minimum is $25. The local sampling service fee for Fresno and Madera county is $65. The initial sample per well per day is $40 and each additional sample is $35. Longer distance sampling is priced by location.

Do you handle escrow water testing for a property sale?

Yes. Escrow water testing is part of this service, along with bacteria sampling, nitrate sampling and additional water quality sampling for private wells and rural systems.

Drinking water sample collection and where the samples go

Drinking water sampling is the work we are asked for most. We come to your wells and sample points, fill and label the bottles, record the chain of custody, which is the paper trail proving who held the sample and when, then drive the samples to the laboratory inside their holding time.

Private well and rural sampling sits here as well. That covers bacteria sampling, nitrate sampling, escrow water testing for a property sale and additional water quality sampling. We are not a laboratory and we do not analyze your samples. The laboratory does the analysis and bills you for it separately.

If the system also needs someone certified attached to it, see our water operator coverage. If the results have to be reported to the state, see compliance and reporting support.
