Monitoring System Provides Early Detection of Water Contamination CheckLight’s technology uses natural luminescent bacteria as early-warning biosensors, positioned inside the monitoring stations. If water is contaminated, the bacteria react by reducing the amount of emitted light, which generates an automatic contamination alert.

Emergency Showers and Eyewash Stations The first 10 to 15 seconds after exposure to a hazardous substance, especially a corrosive substance, are critical. Delaying treatment, even for a few seconds, may cause serious injury. Emergency showers and eyewash stations provide on-the-spot decontamination.

NITROBENZENE If present in high concentrations, these bacteria can cause the well water to have a rotten egg smell. If iron bacteria are present, they can give a musty odor to the water and give the water a brownish tint. Sulfur/iron bacteria are not coliforms so they must be tested for separately. Page 2 of Publication No. 4: Bacteria in Private Drinking Water Wells Testing for Bacteria in Private Drinking Water Wells The primary test to determine the presence of bacteria is the total coliform test. To determine if bacteria are present, arrange to test your drinking water at a state certified laboratory.

BOIL WATER ADVISORY The results of the water sample tests. When water service is restored, a Lab Analyst comes to the site to take water samples from several points in the affected service area. The samples are allowed to incubate up to 24 hours; no less than 18 hours. If the water is contaminated, bacteria will have grown.

- Contaminates typically found in tap water include mercury, copper, microorganisms, and numerous kinds of disinfectants, fertilizers, and medications. Understand how to test water purity via the three main testing procedures: with a test kit, with tests run by your water supplier, or by a professional laboratory. Test kits are not difficult to read. 2  For the test itself, you'll dip test strips into your water. 3  Your kit will come with a chart that will help you read the test strips and determine what is in your water.

Private Well Water If the total coliform bacteria test is “PRESENT” or the number is greater than or equal to 1 (e.g. 1, 2, 3.1, 5.6, 200.5, etc), this result is UNSATISFACTORY and indicates the water is bacterially UNSAFE and should NOT be used for drinking unless properly disinfected before use (e.g. boiling for one minute).

Private Water Wells Naturally sources of contamination. The first step to protect your health and the health of your family is learning about what may impact the quality of your source of drinking water. Microorganisms are bacteria, viruses, and parasites sometimes found in water. Shallow wells are at greater risk of contamination. Runoff, or water flowing over the land surface, may pick up contaminants from wildlife and soils. This is often the case after a flood. These organisms can cause a variety of illnesses. Radionuclides are radioactive elements such as uranium and radium.

- Of 251 chemicals, bacteria, viruses and microbes the scientists measured, 117 were not detected in any of the treated drinking water. Twenty-one were found in water from more than one-third of the 25 utilities (nine or more) and 113 were found in less than one-third (eight or fewer).our of the chemicals found in the samples – the metal strontium, the herbicide metolachlor, PFOS and PFOA – are on the EPA’s list of chemicals under consideration for drinking water standards.
