Water Quality Testing provides accredited lab testing on water samples to determine how safe the water is when it leaves the treatment plant, and whether contaminants remain in the water after chlorine disinfection. This ensures public water supplies are safe to drink and use.

Testing for Emerging Contaminants

To learn more about contaminants of emerging concern, testing is required. In this post, I will divulge more about some of the testing methods and how more has been found about CECs.

Initial Water Sample Collections

At predetermined sites (in this specific study, wastewater treatment plants were being studied), water was collected in clean bottles for a one-time sample. (1) Bottles contained dechlorination chemicals and preservatives to analyze the emerging contaminant concentration against regulated levels. (1)

Method 1: USGS Direct Injection

In this method, the term “direct injection” is used because the water sample is directly injected into a chromatograph then a spectrometer. (2) A chromatograph is an instrument that is used to separate mixtures, like contaminants from a water sample. (3) Once the mixture is separated a spectrometer, an instrument used to measure spectra or light properties of different physical objects. (4) By using this technique, the atomic properties of various pharmaceuticals were found and differentiated, therefore identifying them in the water samples. (2) This method of sampling was used to test for 110 of the 174 contaminants; the contaminants specifically tested for were pharmaceuticals and personal care products. (1)

Method 2:  Purge-and-Trap for Aqueous Samples

The Purge-and-Trap methodology includes either keeping a certain temperature heating an aqueous solution then putting an inert gas through it to release the contaminants into a separate chamber where they are next transferred to a chromatographic chamber. (5) This method is used for aqueous solutions. This method is also validated by the U.S. Environmental Protection Agency (USEPA), meaning the method has been peer reviewed and deemed sufficient to be published for general use. (6)

Method 3: Test Strips

A testing method available for more of the average consumer for use in field testing, test strips involve using a signified test strip then dipping it into a water sample container or directly into the source then measuring a specific contaminant’s concentration by comparing the strip’s new color to a chart of specified concentrations correlated to its respective color. (7) This test very much resembles a pH test, just with a variable. A downside to this method is it isn’t as accurate as a lab method would be, but it gives a general idea about a specific water’s quality. 

Method 4: Color Disk Kits

Another field test kit that isn’t as accurate but is still reputable is the color disk kit test. To conduct this, the user puts some of a water sample in a tube then adds either a powder or liquid reagent to the sample. After this, the tube is placed in a box that lists specific concentrations and their respective color. These values are used to match the sample’s concentration. (7) This test requires some wait time but still gives a good idea about water quality in a given area. 

Method 5: Handheld Field Instruments

One more test method that can be conducted with little experience in water testing is by using specific handheld instruments. Although these tools are more intricate, delicate, and less user friendly, it is still a viable method that yields more accurate results than a test strip or color disk kit. To complete this test, a handheld device such as digital meters, colorimeters, and photometers are utilized with a given water sample. (7) These devices also require batteries and calibration along with being more costly, all of which make them less accessible.

Testing... 1,2,3,... Testing

Although I listed only 5 methods for testing water contamination, there are many more for different kinds of water testing and testing other substances. The U.S. EPA has a page dedicated to sharing their validated testing methods and studied conducted using such methods. (6) As more work is done in fields such as toxicology and environmental analysis, new methods are being constructed and tested. The field continues to grow as new questions arise. 

Solutions for Water Pollution

Home testing kits are available online and in stores to see what your local water quality is. Sometimes free water quality tests are offered through local, state, and federal operations. If possible, test your water quality. If it meets water standards, how was this possible. If it is below expectations, how can you improve the quality?
