MICROBIOLOGICAL TESTING

Overview:

MCCAMPBELL ANALYTICAL OFFERS A WIDE RANGE OF MICROBIOLOGICAL ANALYSES FOR DRINKING WATER, FRESH AND MARINE RECREATIONAL WATER, EFFLUENT, SOIL, SLUDGE AND FOOD.
Our results are rapid and accurate. All results are confirmed either by fluorescence, biochemical or serological procedures.

IN ADDITION TO COMMON BACTERIOLOGICAL TESTS, WE ALSO OFFER TESTING FORWATER SUITABILITY, INHIBITORY RESIDUE, IRON AND SULFUR BACTERIA, LEGIONELLA, PETROLEUM DEGRADING BACTERIA, ALGAE AND YEAST AND MOLDS.

Definitions:

Enzyme Substrate Method: Method using hydrolysable substrates that form either a distinct color or fluorescence in the presence of certain bacteria. Results are reported in MPN.
Membrane Filtration (MF): Method in which sample is filtered through a sterile, 0.45mm-pore, gridded membrane. All of the bacteria in the sample are "trapped" on the surface of the membrane, which is then placed on appropriate media. This allows each bacterium to form a colony on the surface of the membrane. Results are reported in cfu.
MPN (Most Probable Number):Indirect rather than direct enumeration or colony count such as that given by membrane filtration. MPN means that the reported number of coliform bacteria has a higher probability than any other number of being correct, and of being reproducible by duplicate testing.
Multiple-Tube Fermentation (MTF): Method in which replicate tubes of several dilutions are inoculated with sample. Each tube has an inverted vial that is used to detect gas formation resulting from the fermentation of an appropriate carbon-source. Results are reported in MPN.
Pour Plate Method: Method in which sample is mixed with agar prior to solidification. The sample and agar are poured into sterile petri dish that is then allowed to solidify. Each individual bacterium forms a single colony within the agar. Results are reported in cfu.
Presence / Absence (+/-): Determination of the presence or absence of bacteria without enumeration / MPN. All Total Coliform positives MUST be tested for the presence of E Coli or fecal coliforms.
Spread Plate Method: Method in which sample is spread evenly on an agar plate. Each individual bacterium forms a single colony on the surface of the agar plate. Results are reported in colony-forming units (cfu).
Bacteria, Fungi & Algae Tested By MAI:
Algae: Testing is available for the isolation and identification of algae in various environmental samples.
Coliform, Total, & E Coli Bacteria: Testing available for water, soil, sludge and food & reported as +/- , CFU or MPN. Coliform are a group of bacteria present in the gut and feces of warm-blooded animals as well as in other environments. Non-fecal coliforms are expected to be further distributed from the source than fecal coliforms, so that it is possible to have a positive total coliform but negative fecal / E Coli. Total coliform positive (without E Coli confirmation), E Coli positive, and Fecal coliform positive results found in drinking, bathing & recreational waters MUST be reported to the responsible party within 24 hours. Escherichia coli & Enterobacter aerogenes are positive culture controls; Staphylococcus aureus, Proteus vulgaris & Pseudomonas aeruginosa are negative culture controls.
E Coli are a sub-group of coliform bacteria whose presence is deemed by regulation to be diagnostic of the presence of fecal coliform, i.e. positive E Coli confirms the presence of fecal coliform bacteria. Escherichia coli (MUG positive strain) is the positive culture control; Enterobacter aerogenes & Klebsiella pneumoniae (thermotolerant MUG(-) strain) are the negative culture controls (ELAP).
Enterococci: Testing available for water & soil & reported as +/- or MPN. Enteroccoci are a sub-group of the Fecal Streptococci group and that group is designated in Standard Methods for monitoring of fecal contamination in recreational waters. Enterococcus Faecalis & Enterococcus faecium are the positive control cultures for this group; Staphylococcus aureus (nalidixic acid sensitive), Escherichia coli (sodium azide sensitive) & Serratia marcescens (fluorogenic compound not hydrolyzed) are negative culture controls (ELAP). Enterococci are can be associated with both human and animal fecal origins. These bacteria are considered to be more specific as indicator organisms of the sanitary quality of recreational waters than the fecal streptococci or the fecal coliform bacteria. Some important clinical infections caused by Enterococcus include bacterial endocarditis, urinary tract infections, bacteremia, and meningitis to name a few.
Fecal Coliform Bacteria: Testing available for water, soil and some food & reported as MPN or CFU. These bacteria are a sub-group of coliform bacteria defined by regulation as those bacteria capable of producing gas from lactose in a suitable culture medium at 44.5 ±0.2°C. These bacteria are present in the fecal excrement of humans, livestock and wildlife. A positive result for fecal coliform bacteria in a sample indicates fecal contamination, which can result from several sources including the direct discharge of waste from mammals and birds, from both agricultural and storm runoff, and from untreated human sewage. Fecal coliform bacteria are used as indicator organisms, and their presence can indicate a higher risk of pathogens being present in the contaminated sample. These pathogens can cause many diseases including, but not limited to, dysentery, typhoid fever, viral or bacterial gastroenteritis, and Hepatitis A. Escherichia coli & Klebsiella pneumoniae (thermotolerant strain) are positive culture controls; Enterobacter aerogenes is the negative culture control (ELAP).
Fecal Streptococci: Testing available for water & soil & reported as MPN. Enterococcus faecalis is a positive control culture for this group; Staphylococcus aureus & Escherichia coli are negative culture controls (SM Table 9002:V). Enterococci positives are diagnostic of the presence of Fecal Streptococci but Enterococci negatives are not definitive of the absence of Fecal Streptococci. For example, equine or bovine fecal material may contain or be characterized by other Streptococci bacteria.
Heterotrophic Plate Count (HPC): Testing available for water, soil & food & reported as CFU or MPN Provides an approximate enumeration of total numbers of viable bacteria yielding useful information about water quality and water treatment efficiency.
Iron and Sulfur Bacteria: Testing is available for iron and sulfur bacteria. The method applied is microscopic examination and culture. Various culture media are used to isolate most if not all the iron and sulfur bacteria in a sample. Results are expressed either +/- or CFU.
Legionella: Testing is available for the enumeration of Legionella in water and other environmental samples. Legionella is the primary human pathogenic bacterium and causative agent of Legionnaires' disease, also known as legionellosis. Results are expressed in CFU.
Pseudomonas aeruginosa: Testing available for water & soil. These bacteria are commonly found in of soil and water, in addition to the surfaces of plants. Pseudomonas aeruginosa is a pathogen of plants as well as humans. Pseudomonas aeruginosa is an opportunistic pathogen that can cause urinary tract infections, respiratory system infections, dermatitis, soft tissue infections, bacteremia, bone and joint infections, gastrointestinal infections and a variety of systemic infections in immuno-compromised and immuno-suppressed patients. People who are seriously affected by Pseudomonas aeruginosa include AIDS patients, cancer patients, burn victims, and people with cystic fibrosis. Results are reported in CFU.
Salmonella: Enumerative testing available for water only, but +/- testing of Salmonella in both soil and water samples. Salmonellae live in the intestinal tracts of both warm and cold-blooded animals. These organisms cause enteric fever and gastroenteritis in humans. Environmental sources of the organism include water, soil, animal waste, raw meat, raw poultry, and raw seafood.
Staphylococcus aureus: Testing available for enumeration of S. aureus in food, soil, and water samples. S. aureus is found most commonly in human nasal passages. This bacteria is considered a pathogen of humans, as it causes skin infections and infections associated with wounds, pneumonia, mastitis, and toxic shock syndrome. S. aureus also causes food poisoning by releasing enterotoxins in food and is one of the most common causes of hospital-acquired infections in patients. Foods that are frequently sources of staphylococcal food poisoning are meat and meat products, poultry, eggs, mayonnaise-based salads including egg, tuna, chicken, potato, and macaroni, and various bakery products.
Yeast and Mold Count, Total: Aerobic plate count of yeast and molds in food, soil, and water samples.

PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) TESTING

PFAS are a large group of complex manufactured chemicals that have been used in a variety of industries around the globe since the 1940s. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) were the most widely manufactured and are still present in the environment. PFAS chemicals keep food from sticking to cookware, make clothes and carpets resistant to stains, and create firefighting foam that is more effective. PFAS are used in industries such as aerospace, automotive, construction, electronics, and military.

PFAS molecules are made up of a chain of linked carbon and fluorine atoms. Because the carbon-fluorine bond is one of the strongest, these chemicals do not degrade in the environment. Because of their extensive use and their persistence in the environment, many PFAS are found all over the world and are present at low levels in a variety of food products and in the environment.

McCampbell Analytical (MAI) has completed a full validation package with the use of ultra sensitive LC-MS-MS equipment to provide low reporting limits and maintain proper chemical resolution in over 40+ PFAS compounds for soil and groundwater and 18 compounds for drinking water.

POLYNUCLEAR AROMATIC HYDROCARBONS (PAH)

Polynuclear Aromatic Hydrocarbons (PAH) Testing

We routinely use high performance liquid chromatography (HPLC) for PAH analysis because it offers better sensitivity than GC-MS, and it permits compound confirmation by use of fluorescence – UV dual detectors.
PNA and PAH are the same thing. PNA= PolyNuclear Aromatic Hydrocarbon

GC/MS analysis in the SIM mode for PNAs is our norm by mass spectrometry because of its greatly increased sensitivity relative to the normal GC-MS scan mode.

MISCELLANEOUS TESTING

We offer additional services, such as R&D, ORC Bench Studies as well as Preparative Clean Up. If you don't see what you are looking for, give us a call.

ORC Bench Studies

We have performed several bench studies assessing ozonation by-products of natural aquifers simulated using coeval soil borings & groundwater.
Client specifies conditions, such as water: soil ratios, dose, and chemical constituents of interest. Various ORCs (oxidant release compounds) can be used, for example MnO4-, H2O2, S2O8-2, O3.
Custom large volume reaction vessels allow multiple fluid withdrawals without significantly effecting experimental water: soil ratios.
We provide a detailed report, complete with chemical reactions, experimental data, bench & analytical QC & data interpretation.
MAI is responsible for the data from start to finish. By-products & water quality parameters can exhibit very complex behavior, largely controlled by experimental & analytical technique, & MAI's oversite for this kind of data is crucial. The relationship between ORC dose & contaminant decrease is much simpler & in this context MAI can provide chemical analyses on client provided fluids without experimental oversite.

Industrial Process Research & Development

Develop or use existing assay tests for product formulations.
Improve chemical process efficiency by reducing process waste & increasing yields thru the determination of product & reactant mass balances at each manufacturing stage.
Measure trace impurity levels harmful to product quality
IDENTIFY UNKNOWN SUBSTANCES OR CONTAMINATION
CTAS (COBALT THIOCYANATE ACTIVE SUBTANCES)

Preparative Clean Up

Hydrocarbon fuels & oils, metabolites, biological or food matrix & elemental sulfur are common chromatography interferents. Without clean-up, dilution is required, & the loss of analyte sensitivity may render the data unusable.
Various types of clean-ups are available from MAI, including GPC (Gel Permeation Chromatography), bench column chromatography, in-a-vial sorption, & chemical treatment.
Clean-up techniques are best applied to restricted target groups because the specific chemical affinity of the target analytes is the key to the separation process. 'Basket' methods such as EPA 8270 have no useful clean-up procedure whereas restricted chemical groups such as PCBs, PNAs and dioxins have very effective clean-ups.
GPC (EPA 3660) is applied to matrices containing biological (cell material, peptides, proteins, triglycerides, fats/oils) interferents and/or elemental sulfur & combines size exclusion & affinity chromatography. It is not sufficient by itself to clean up natural matrices but can be a useful starting point, especially for time integrated SPMD samples.
Bench column chromatography (EPA 3600) primarily uses silica gel, alumina or florisil as sorbents in affinity chromatography & requires skilled chemists, well developed techniques & accompanying QC data for effective use.
Chemical treatments, such as water washing to separate water soluble from water-insoluble compounds, or acid-permanganate clean-up of PCBs in oils, are generally less effective than bench column chromatography but are inexpensive & have situational applications.
MAI can perform customer specifed clean-up procedures or develop custom clean-up procedures upon request.
