What National Testing Laboratories does

National Testing Laboratories (NTL) is a private, ISO/IEC 17025:2017-accredited drinking water testing laboratory founded in 1985 and headquartered in Cleveland, Ohio, with its main analytical facility in Ypsilanti, Michigan. The company provides a comprehensive suite of mail-in water testing kits and laboratory analysis services organized under the WaterCheck™ (well water) and CityCheck™ (municipal water) brand families, each offered in Basic, Standard, and Deluxe tiers covering 32 to 115+ analytes. Core analytical methods include microbiological testing (SM 9215, SM 9223), metals analysis covering 24 metals including lead, arsenic, mercury, and uranium via EPA 200.7/200.8 and SM 3113, volatile organic compounds (EPA 524.2), pesticides and herbicides (EPA 505, 515.4, 547), and radiological testing (EPA 900.0, 903.1, 904.0).

NTL serves a diverse customer base: residential homeowners (primary segment) with private wells or municipal supply concerns; water treatment professionals via the Dealer Advantage Program; over 400 bottled water and beverage plants requiring FDA, IBWA, 50-State, and WHO Edition compliance; public water systems; medical and research laboratories; home inspectors and realtors (via the Quick Series rapid-turnaround line); and well drillers. Pricing follows a unit-based, pay-as-you-go model ranging from $159 (WaterCheck Lite) to $565 (Deluxe Radiological), with commercial compliance testing quoted on request. Distribution combines direct-to-consumer e-commerce at watercheck.com, inside sales through Technical Service Representatives, dealer resellers, and a mutual referral partnership with Environmental Hazards Services, LLC for specialized lead/asbestos/PCB/mold testing.

The company is certified in 38 states and territories, holds NELAC certification (#E87753), and participates in the USEPA Proficiency Testing Program. Over its 35+ year operating history, NTL has processed more than 200,000 home water samples and over 1,000,000 individual tests, serving thousands of residential customers and 400+ commercial accounts. A July 2026 website notice indicated that current sample volumes are running above historical baseline, resulting in extended turnaround times — a signal of demand growth that the company's lean operational structure (11-50 employees) is working to absorb.
