Frequently Asked Questions

Do I need a permit to drill a well in Union County?

Yes. Union County Environmental Health permits private drinking-water wells. The fee is $500 and a site plan is required (fees).

How deep are wells in Union County?

It varies by site. USGS records for about 140 bedrock wells give a median of about 120 ft, with the 90th percentile around 255 ft (source).

How much does a new well cost?

An estimated $4,525–$12,365 at the median depth, and more for deeper wells. See the cost guide.

What should I test my well water for?

New wells in NC must be tested for arsenic, manganese, iron, nitrate, pH and bacteria. Arsenic deserves attention in Slate Belt areas of the county.

How far must a well be from a septic system?

State rules set a 50 ft minimum from a single-family septic tank and drainfield. Other setbacks apply too, and the county reviews the site plan.

Are you a well drilling company?

No. This site is an independent referral service. We connect you with an independent NC-certified well contractor and don't perform any work ourselves.

Is the referral free?

Yes. There's no charge to homeowners. Participating contractors may pay us for marketing.
