The City of Lake Havasu City, Arizona, is issuing a sole‑source exemption to purchase a single unit 4540 E‑Gauge Low Activity Nuclear Density Gauge for use by its Streets and Water Division. The gauge uniquely performs soil and asphalt testing without requiring NRC licensing, radiation‑safety training, or specialized storage, making it the only viable product on the market.
