Ensuring Safe Drinking Water: Why Public Water Testing Matters
If your home is in Oregon and relies on a private well for its water supply, you are the sole steward of its safety and quality. Unlike public water systems that undergo routine testing, private wells require proactive monitoring by homeowners to ensure the water is safe for drinking, cooking, and other household uses. Alexin Labs provides comprehensive and reliable well water testing services designed specifically for homeowners like you, offering peace of mind and protecting your family’s health.

Why is Water Testing Crucial for Publicly Treated Water?
Public water systems in Tigard and across the nation adhere to strict regulations set forth by the Safe Drinking Water Act (SDWA). These systems employ sophisticated treatment processes to remove contaminants. However, even with these measures in place, several factors necessitate ongoing and comprehensive water testing:
Regular testing acts as a crucial check on the treatment processes. It confirms that disinfection methods are effectively eliminating harmful bacteria and that filtration systems are removing sediment and other particulate matter.
Scientific understanding and analytical capabilities are constantly evolving. Testing allows for the identification of new or previously undetected contaminants that may pose health risks.
Aging pipes and distribution systems can sometimes introduce contaminants into the treated water as it travels to your tap. Testing can help pinpoint these issues.
In the event of natural disasters, spills, or other emergencies, increased testing is crucial to assess potential contamination and ensure the water supply remains safe.
Transparent and consistent water testing provides the community with confidence that their drinking water is safe and that the water provider is committed to public health.
Common Water Tests Performed on Publicly Treated Water
Public water systems routinely conduct a wide array of tests to monitor water quality. Here are some of the most common categories and specific analyses:
1. Microbiological Testing
Total Coliform and E. coli: These bacteria are indicators of potential fecal contamination and the possible presence of disease-causing pathogens.
Enterococci: Another indicator of fecal contamination, often used to assess the safety of recreational waters but also relevant for source water monitoring.
Giardia and Cryptosporidium: These protozoan parasites can cause gastrointestinal illness and are resistant to standard chlorine disinfection. Monitoring for these is often required for surface water sources.
Heterotrophic Plate Count (HPC): This test measures the overall level of bacteria in the water and can indicate potential issues with treatment or distribution.
2. Chemical Testing (Inorganic Contaminants)
In addition to the annual screening, consider a more comprehensive analysis that includes:
Nitrate and Nitrite: Primarily from agricultural runoff and wastewater, high levels can be harmful, especially to infants.
Arsenic: A naturally occurring element that is toxic at elevated levels.
Lead and Copper: These metals can leach from aging plumbing systems and pose significant health risks. Public water systems monitor source water and often conduct tap sampling in higher-risk areas.
Fluoride: Added to many public water supplies for dental health benefits, levels are carefully monitored.
Metals (e.g., Mercury, Cadmium, Chromium): These can originate from industrial discharges or natural sources and are regulated due to their toxicity.
3. Chemical Testing (Organic Contaminants)
Volatile Organic Compounds (VOCs): These can come from industrial solvents, fuels, and other sources. Regulations cover a wide range of VOCs like benzene, toluene, and trichloroethylene.
Synthetic Organic Compounds (SOCs): This category includes pesticides and herbicides used in agriculture and landscaping.
Disinfection Byproducts (DBPs):
-
- Trihalomethanes (THMs): Formed when chlorine reacts with organic matter (e.g., chloroform, bromoform).
- Haloacetic Acids (HAAs): Another group of DBPs formed during disinfection.
-
4. Radiological Testing
Gross Alpha and Beta Activity: These are screening tests for overall radioactivity.
Radon: A naturally occurring radioactive gas that can dissolve in groundwater.
Uranium and Radium: Naturally occurring radioactive elements that can be found in certain geological formations.
Physical Parameters
Turbidity: Measures the cloudiness of the water, indicating suspended particles that can clog irrigation systems or affect water palatability for livestock.
Temperature: Can impact water quality and animal consumption.
Sediment: Can clog irrigation systems and carry contaminants.
