Perform Park-wide Cross Connection Survey, Cross C

The National Park Service Pacific West Region is soliciting quotes for a cross-connection survey, cross-connection control plan development, and annual backflow prevention testing services at Death Valley National Park in Inyo County, California. The contractor must conduct comprehensive hazard assessments across eight water systems containing 265 total service connections, identify actual and potential cross-connections, verify backflow prevention device presence and condition, test 67 backflow prevention assemblies, and develop separate Cross-Connection Control Management Plans for each water system aligned with California State Water Resources Control Board requirements. Key qualifications include personnel holding current Certified Cross-Connection Control Specialist and Certified Backflow Prevention Assembly Tester certifications recognized by the State Water Resources Control Board. The evaluation will be based on three factors: price, personnel screening requiring the specified certifications, and past performance demonstrated through three documented project references completed within the past five years. The solicitation deadline is March 18, 2026, at 1:00 PM Pacific Time, with Amendment #1 issued on March 11, 2026, to address vendor questions and extend the original March 17 deadline.
