Are there wells or sites that are not candidates for low-flow sampling?
Every site is a candidate for low-flow sampling, if it is accepted in your region. Even if you’re replacing existing equipment, low-flow sampling will usually yield savings after no more than 6 sampling events. If you’re installing a new system, or if purge water handling/disposal costs or purge labor times are high, dedicated low-flow systems can pay for themselves in as little as 2-4 sampling events.
