Water Lab

SJBPH’s Environmental Health program provides water testing for southwest Colorado residents. Water Bacteriology testing determines the absence or presence of Total Coliform and E.Coli bacteria.

A test bottle and requisition form must first be obtained from the Durango SJBPH front desk. The cost of this test is $25.00 and results are usually provided within 24 hours. The sample must be received and tested within 30 hours of collection. As such, the Water Lab cannot receive samples on Friday. Samples are accepted Monday through Thursday, 8 a.m. to 4 p.m. only.

The Water Lab will not be accepting samples during the Christmas and New Years’ Day observances Dec. 21-25 and Dec. 28 – Jan. 1.
