Our Services
We provide accurate, timely, and compliant results. We are locally owned and operated and we employ local scientists to analyze samples in our modern laboratory.
Wet Chemistry
Samples are routinely digested for tests such as total Kjeldahl nitrogen (TKN), total phosphorus, or for elemental analysis. Titrations are done for total residual chlorine and alkalinity. Other tests include five-day biochemical oxygen demand (BOD), carbonaceous BOD, chemical oxygen demand (COD), total suspended solids (TSS), settleable solids, total solids and ash, flashpoint, and toxicity characteristic leaching procedure (TCLP).

Instrumental Analysis
Common tests that are conducted with the help of instrumentation include: ammonia, total and amenable cyanide, elemental analysis, hexavalent chromium, oil and grease, total phosphorus, total Kjeldahl nitrogen, anions (fluoride, chloride, bromide, nitrite, nitrate, o-phosphate, and sulfate), total hardness, and total phenolics.

Microbiological Assays
A variety of microbiological assays are performed routinely. The most common microbial assays are E. coli and total coliforms using a Quanti-Tray system and fecal coliforms by membrane filtration. Other microbial assays include heterotrophic plate count (HPC) and iron-related bacteria.
