Cryptosporidium and Giardia
Cryptosporidium are tiny, little protozoan pathogens found naturally in water. When it is ingested, it can cause a wide range of manifestations, from asymptomatic infections to severe, life-threatening illness. Typical gastrointestinal illness includes diarrhea, vomiting, or cramps
A laboratory must be certified to perform testing for Cryptosporidium.
EPA Method 1623.1: Cryptosporidium and Giardia in Water by Filtration/IMS/FA
EMSL Test Codes: M640–M643
EMSL is fully approved by the U.S. EPA for LT2* rule (Long Term 2 Enhanced Surface Water Treatment Rule) Cryptosporidium monitoring program using EPA Method 1623.1. EMSL is an industry-leading laboratory with the largest sample capacity for LT2 testing. EMSL holds certification for the following states: AL, AR, CA, CT, CO, DE, FL, GA, ID, IL, IN, IA, LA, ME, MD, MA, MI, MO, NE, NJ, NM, NY, NC, ND, OH, OK, PA, RI, SC, SD, TN, TX, UT, VA, WV, WI, and WY.

Taste and Odor
There are many causes and sources for taste and odor problems in drinking water. The most sources are organic and derived from algal blooms in surface water.
Step 1
Geosmin and MIB (SM 6040D)
EMSL Test Code: M617
Geosmin and 2-Methyl-Isoborneol (MIB) are compounds having a very strong, earthy taste and odor. They are naturally produced by some types of algae and bacteria and can be detected by human noses at very low levels (above 10 ppm). They cannot be removed from water using normal treatment processes.
- Turnaround Time: 3 days, one week, two weeks
- Sampling and Shipping: Two 40 mL samples without any air bubbles in bottle(s), overnighting on ice
- Holding time: 3 days without preservatives and 7 days with preservatives

Step 2
Algae Identification
EMSL Test Codes: M601 and M602
To confirm the possible source in the water, algae, including cyanobacteria (blue green algae), can be identified and enumerated at both genus (M601) and species level (M602). See here for details.
Step 3
Biomass Analysis
EMSL Test Codes: 605, M606, M612, M614, M615, M616, M624
The last step is to quantitatively estimate the biomass of cyanobacteria and algae. The simplest way is to analyze the dry weight (M612). For more detailed results, chlorophylls are great option, which include chlorophyll a, b, c, pheophytin a, and Phycocyanin (M614, M615, M616, and M624). Furthermore, for some research purpose biovolume is required (M605 and M606). See here for details.
Cyanobacteria/Blue Green Algae
Cyanobacteria are a group of bacteria, although they are traditionally included among algae because both are photosynthetic organisms. Cyanobacteria therefore is also called blue green algae. Cyanobacteria may cause harmful agal blooms (HABs). There has been an increase in harmful agal blooms. Some HABs are associated with algae-produced toxins.
M623 Comprehensive Cyanobacteria Analyses (3 tests) is your first choice for HAB.

MPA involves the identification, sizing, and population estimates of microorganism and organic or inorganic debris found in water.

Resistance to Algal Detachment (ASTM D5589)
Defacement of paint and coating films by algal growth is a common phenomenon under certain conditions. This test method attempts to
provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions, such as lighting, temperature, and humidity.
At EMSL, we simulate the required testing conditions to evaluate resistance of films, coatings, or other materials to evaluate the resistance to algal detachment.
Turnaround Time: 4 weeks
Holding time: None
Sampling and supplies: No special requirement
Toxicity testing
MicrotoxTM
MicrotoxTM is an in vitro test system that uses bioluminescent bacteria Vibrio fisheri for the detection of toxicity in water. MicrotoxTM is used is used as a screening system to detect the relative toxicity of a sample. The results are normally expressed as an effective concentration (EC) values or as a % inhibition compared to a control.

Wastewater Biomass Analysis (filamentous bacteria)
Do you encounter problems with your wastewater treatment systems such as foaming, sliming or bulking flocs that are difficult to settle or dewater? It is very important to perform the microscopic biomass analyses of a wastewater treatment system and understand the organisms, including higher life forms and filamentous bacteria. The detailed wastewater biomass analysis will indicate the mechanisms behind the flocs, including low DO, Low F/M, low pH, low nutrients, septicity, and grease and oil.
Turnaround Time: 3 days, one week, two weeks
Sampling supplies: Product ID: 8714206 (free)
Holding time: 48 hours
Sampling and supplies: 500 mL of wastewater and shipping overnight on ice to the lab.

Microplastics
Microplastics are defined as any plastic particle less than 5mm in size in any one direction. There is no defined lower size limit however, convention and instrument capability generally dictate 1 micron diameter.
Primary microplastics consist of manufactured raw plastic material, such as plastic pellets used to manufacture parts and micro-beads which have application in a wide range of products such as cleaning agents. Secondary Microplastics originate from larger plastic products or macro plastic fragments that have broken down due to mechanical, UV radiation or chemical means producing particles less than five millimeters.
Microplastics Sampling
Water samples may be collected in rinsed plastic or glass containers. Environmental samples such as lake and stream water, rain runoff, ponds and other silty bodies of water require a minimum of one liter. Cleaner waters such as seawater away from the wave break region, pools and potable water are better analyzed with a one-gallon minimum volume.
Soil and similar solids may be collected by shovel or applicable device and placed into a rinsed one-gallon Zip-lock™ style bags, buckets, or jars. Whenever possible submit a minimum sample approximately one liter in volume; however smaller amounts can also be analyzed when sample volume is limited. Beach sand is typically collected along the wrack line which is the point of high tide where sticks and other debris accumulate. This is also the point where the highest concentration of Micro-plastics is usually found.
Air samples may be collected using 0.1μm or 0.4μm polycarbonate filter cassettes. Flow rates may vary but a total volume exceeding 1000 liters is recommended for area samples. Personnel monitoring samples are typically run at 1.5 to 2.5 liters per minute for the intended test duration and are not subject to the volumes suggested for area sampling.
Food and beverages may be submitted in Zip-lock™ style bags, jars or, in the case of unopened food or beverages, in their original containers. Food and beverage samples should be shipped on ice (ice packs) in appropriate coolers for maintaining a cool environment during shipping.
Microplastics Analysis
Multiple reporting styles are available starting with the Basic Microplastics Analysis which includes total microplastics count and sizing information obtained by sieve and fluorescent microscopy to Full Microplastics Analysis which includes the polymer identification with size separation based upon the types of plastics observed. Macroplastics (size >5mm), if found, are also reported for informational purposes but not included in the sizing data.
