Coliform Sampling There are a variety of bacteria, parasites, and viruses which can cause health problems when humans ingest them in drinking water. Testing water for each of these germs would be difficult and expensive. Instead, water quality and public health workers measure for the presence of bacteria in drinking water using coliform bacteria as an indicator. The presence of any coliforms in drinking water suggests that there may be disease-causing agents in the water. We have 499 resources (and counting) on Total Coliform in our Documents Database that provide valuable information on this topic. You can search for documents on potential pathways for coliform contamination, coliform bacteria and well water sampling, best practices for coliform sampling, and many other useful guides that will help you to deliver safe and clean water to utility customers. To access the wealth of knowledge on Total Coliform within our database just select "CATEGORY" in the dropdown then choose "Total Coliform." Once you make that selection, a second dropdown will appear where you can choose "HOST," “TYPE,” or “STATE” to narrow the search even further.

Stormwater Runoff Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (i.e. paved streets, parking lots, building rooftops, etc.), it accumulates debris, chemicals, sediment, and other pollutants that could adversely affect water quality if the runoff is discharged untreated. Storm sewers can be connected to sanitary sewers and is treated as wastewater when that is the case, so that when discharged it is better for the environment. We have 554 resources (and counting) on Stormwater in our Documents Database that provide valuable information on this topic. You can search for documents on wet weather management strategies, how to verify the source of inappropriate discharges to storm drainage systems, how to develop a CSO Long-Term Control Plan, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Source Water Protection Source water is untreated water from streams, rivers, lakes, or underground aquifers. It is used to provide public drinking water and it supplies private wells with water used for human consumption. In order to give water utilities and community members the information they need to decide how to protect drinking water sources, the Safe Drinking Water Act requires that the states develop EPA-approved programs to carry out assessments of all source waters in the state. We have over 2,300 resources (and counting) on Source Water in our Documents Database that provide valuable information on this topic. You can search for resources like the Drinking Water Mapping Application to Protect Source Waters (DWMAPS), a guide to groundwater protection, a Ground Water Rule compliance manual for water systems and states, an FAQ on abandoned wells, a flowchart to help determine groundwater sources under the direct influence of surface water (GWUDI), and many other useful guides that will help you to deliver safe and clean water to utility customers.

Sanitary Sewer Overflows Properly designed, operated, and maintained sanitary sewer systems are meant to collect and transport all of the sewage that flows into them from a community into a wastewater plant for treatment. Sanitary sewers are the things we flush, pour down drains, etc. There are regulations that say stormwater and sanitary sewers are to be completely separate, but in many older, large communities they run together and can overload a wastewater plant. We have 810 resources (and counting) on Sanitary Sewers in our Documents Database that provide valuable information on this topic. You can search for documents about the development process for publicly owned treatment works (POTW), benefits of protecting your community from sanitary sewer overflows, how to develop a collection system maintenance program, combined sewer overflow management, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Safety Tips for Water Operators According to the National Safety Council, accident rates continue to be high for the water industry, even when compared with other high-risk fields such as construction and mining. It's important for water operators to be informed on accident prevention practices and safety procedures to protect themselves from the hazards associated with this essential role. We have 400 resources (and counting) on Safety in our Documents Database that provide valuable information on this topic. You can search for documents about pathogen exposures for workers in the onsite industry, health hazards in wastewater treatment plants, confined space safety guidelines, lockout/ tagout practices and procedures, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Radioactive Contaminants in Water Most water sources have very low levels of radioactive contaminants, most of which are naturally occurring, although contamination from human-made nuclear materials can also occur. Most radionuclides are at levels that are low enough to not be considered a public health concern. At higher levels, long-term exposure to radionuclides in drinking water may cause cancer. In addition, exposure to uranium in drinking water may cause toxic effects to the kidneys. Radiation found in sewage sludge and the ash from its incineration may be from Nuclear Regulatory Commission licensees, industrial discharges, and TENORM. We have 100 resources (and counting) on Radionuclides in our Documents Database that provide valuable information on this topic. You can search for documents on the management of radioactive residuals from drinking water treatment, approved analytical methods for monitoring radionuclides, uranium as a drinking water contaminant, federal regulations on the disposal of residuals containing radionuclides, and many other useful guides that will help you to deliver safe and clean water to utility customers.

Public Notification & Emergency Communication Public Notification Rule is intended to ensure that consumers will always know if there is a problem with their drinking water. These notices immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health. They also notify customers if their water does not meet drinking water standards, the water system fails to test its water, or if the system has been granted a variance (use of less costly technology) or an exemption (more time to comply with a new regulation.) Consumer Confidence reports (CCRs) are an annual report of the status of the drinking water at a facility that are also required. However, CCRs do not necessarily report problems, but a status. We have 731 resources (and counting) on Public Notification in our Documents Database that provide valuable information on this topic. You can search for documents about how states are responding to health advisories for water systems, ways to prepare for a drought related water shortage, advice for working with news media, boil water advisories during natural disasters, and many other useful guides that will help you to deliver safe and clean water to utility customers.
