T-Creek is able to provide a number of tests for drinking water and non-potable water. These test methods encompass simple physical property tests to more complex procedures for total nutrients. We specialize in low-level nutrient detection at affordable rates.
T-Creek offers drugs of abuse testing that is customizable for your specific needs. In addition to pre-employment, random, and reasonable suspicion drug testing, we offer DOT drug testing. Collections can be completed by qualified T-Creek staff at our laboratory or on-location. All substance abuse specimens submitted to T-Creek are tested using an objective, computerized, and automated method to ensure reliable results.
T-Creek also provides our customers with a large selection of fast, accurate, and reliable drug screening products that are 100% manufactured in the USA. These products are adjustable for up to 15 drugs of abuse, alcohol, and adulterants.
Chain of Custody
We use best practice methods throughout the testing process and adhere to a very strict chain of custody.
We offer a couple different methods for detection of coliform in water. We use a presence/absence method for drinking water – which detects total coliform, E. coli, and fecal – and a membrane filtration analysis for fecal coliform and E. coli in surface water. The latter method allows for enumeration of colonies with a result of CFUs/100 mls of sample.
We use ion chromatography per EPA Method 300.0 to determine the concentrations of six different ions in drinking and non-potable water: fluoride, chloride, nitrite, nitrate, ortho-phosphate, and sulfate.
We offer several methods for determining the physical characteristics of drinking and non-potable water samples. These include methods for alkalinity, conductivity, pH, total hardness, total dissolved solids, total suspended solids, and turbidity. Additionally, we perform chlorophyll determinations and zooplankton identifications.
We offer low-level nutrient analysis at competitive rates for ammonia, total nitrogen, ortho-phosphate, total phosphorus, and total dissolved phosphorus. This type of analysis reduces non-detect results for oligotrophic bodies of water.
Plant and Soil Analysis
We can analyze plant (including macrophytes) and soil samples for biomass, nitrate, nitrite, total phosphorus, and total nitrogen.
5-Panel Test Package
Our standard 5-panel test analyzes for amphetamines, buprenorphine, cannabinoids, cocaine, and opiates. However, we are able to complete other drug assays based on client needs.
In addition to our typical 5-panel test, we offer DOT (Department of Transportation) testing for pre-employment candidates or employees that are professional transportation drivers, in safety-sensitive positions, or in certain federal positions. The DOT drug panel tests for amphetamines, cannabinoids, cocaine, opiates, and PCP.
Creatinine and Adulterants
All of our drug testing packages come with an analysis for creatinine. This helps determine whether the sample was diluted during the sampling process, or whether the applicant attempted to “flush” their system with excessive amounts of water or diuretics.
We also have the option of testing for adulterants – substances that may be introduced by the applicant during the sampling process.
Drug Screening Products
We provide our customers with a large selection of fast, accurate, and reliable drug screening products that are 100% manufactured in the USA.
A minimum order quantity of 25 (1 box) is required to order stock products. All other products require a minimum order quantity of 200 (8 boxes).
