Obtaining The Necessary Sampling Units
Prior to contacting the DEQ State Laboratory to request sampling units, customers with private wells should discuss their water quality concerns with Local Health Department Sanitarians. These professionals can offer advice on the type of testing which is appropriate for their situation.
SAMPLES WHICH ARE NOT SUBMITTED IN THE CORRECT SAMPLE UNIT FOR THE TEST REQUESTED MAY NOT BE ANALYZED BECAUSE OF POSSIBLE INTERFERENCE, IMPROPER PRESERVATION, OR OTHER CONCERNS THAT MIGHT AFFECT THE RESULTS.
In most cases, only a single test should be requested for each sample container submitted. Exceptions are Unit 33 (inorganic) and Unit 36ME (metals) which are applicable to several analyses on the test list and contain sufficient volume for multiple tests.
Sample container units are described on the "Requisition of Water Sample Units" form. Note that the numbers identifying each type of unit (under heading, UNIT NUMBER) correspond to those given on available test listings. Sample unit numbers should be used as catalog numbers when ordering sample containers.
Containers for use in the DEQ laboratory may be obtained in the following ways:
- Many Local Health Departments (Environmental Health Offices) maintain a small supply of most types of sample units. Check with your local health department office for fastest service for small amounts of sampling.
- All types of sampling units can be obtained from the laboratory. Submit a completed sample unit requisition form by one of the following methods:
