Welcome! I’m so glad you’re interested in learning more about water testing. Having access to clean, safe drinking water is incredibly important for our health and wellbeing. In this post, we’ll dive deep into everything you need to know about water testing, with a special focus on Gray, Maine.
An Introduction to Water Testing
Before we get into the specifics, let’s start with the basics – what is water testing and why does it matter?
Water testing involves analyzing water samples for various contaminants and characteristics. There are many reasons to test water:
- To monitor drinking water quality and ensure it is safe for human consumption
- To detect and address contamination issues in private wells or public water systems
- To monitor environmental waterways for pollution and track water quality trends over time
- To ensure compliance with local, state, and federal regulations for drinking water standards
Some of the most common water tests check for:
- Microbiological contaminants like bacteria, viruses, and parasites
- Chemical contaminants like pesticides, industrial chemicals, and heavy metals
- Physical characteristics like pH, hardness, and turbidity
Regular water testing provides vital information to protect public health. For private well owners, it can alert you to problems and allow you to take corrective action if any contaminants are detected at unsafe levels. Public water utilities use water testing in Gray Maine data to adjust treatment methods as needed.
Why Test Your Water in Gray, Maine?
Now that we’ve covered the basics of water testing, let’s talk about why it’s important specifically in Gray, Maine.
Gray gets its drinking water from Branch Brook, a surface water source. The Maine Drinking Water Program (DWP) closely monitors Gray’s water quality and requires regular testing for a range of potential contaminants. As is true with all public water systems, the safety of Gray’s drinking water relies on rigorous sampling, testing, treatment, and source water protection.
For those Gray residents who use private wells for drinking water, regular water testing in Gray Maine is even more crucial. Private wells are not regulated by the DWP and well owners are responsible for monitoring and maintaining water quality themselves. The only way to know if your well water is safe to drink is to test it. Private wells are susceptible to contamination from nearby pollution sources like septic systems, road runoff, and agricultural activities.
Maine as a whole is lucky to have abundant natural water resources. But taking clean water for granted would be a mistake. Both public and private water supplies need monitoring and protection to prevent pollution issues down the road. The Maine DWP recommends private well owners test their water annually for bacteria and nitrates, and every 5-10 years for other baseline parameters like arsenic, pH, metals, hardness, and conductivity. Catching problems early allows for a more cost-effective solution.
Common Water Contaminants to Test For
Now let’s go over some of the most important water contaminants to test for in Maine, including Gray. This will give you an idea of what to look for in your water test results.
Microbiological Contaminants
Bacteria, viruses, parasites, and other microbiological contaminants are some of the most urgent and frequent water quality problems. Common examples in Maine include:
- Coliform bacteria – Fecal coliform bacteria and E. coli indicate possible sewage contamination.
- Giardia lamblia – Parasite from animal feces that causes gastrointestinal illness. Surface water is at higher risk.
- Cryptosporidium – Another gastrointestinal parasite, also more common in surface water.
For private wells, annual tests for total coliform bacteria are highly recommended. Public water systems regularly test for microbiological contaminants as well. Proper disinfection and maintaining system integrity prevents these types of contaminants.
Nitrates/Nitrites
Runoff from fertilizers, animal manure, and septic systems frequently makes its way into Maine groundwater. Infants are particularly vulnerable to nitrate/nitrite poisoning, so testing is important for households with pregnant or nursing mothers.
Arsenic
A naturally occurring element, arsenic is very common in Maine well water. Long-term exposure has been linked to cancer, heart disease, and other health effects. Arsenic is odorless and tasteless in water, so testing is the only way to know it’s there.
Radon
An invisible, radioactive gas, radon can dissolve and accumulate in well water drawn from rocky Maine aquifers. It’s the second leading cause of lung cancer after smoking. A radon test is recommended for all homes, since the gas can also enter buildings through soil and crawl spaces. Proper venting and seals can lower radon levels if detected.
Lead
Corrosive water can cause lead to leach from pipes, plumbing fixtures, and solder in older homes. Lead damages neurological development in children. Periodic tests are prudent to check for pipe corrosion issues. Flushing pipes thoroughly minimizes lead exposure from household plumbing.
This list gives a starting point on what to look for, but many other inorganic chemicals like copper, manganese, and chloride are worth testing for as well.
How and Where to Test Your Water
If you want to have your water tested, either for a private well or public system, here are some key steps:
1. Determine what to test for
Use the lists above to decide what parameters are relevant to your water source and household needs. Additional contaminants to consider include VOCs, SOCs, cyanide, fluoride, sodium, hardness, and turbidity.
2. Find a certified lab
In Maine, look for a lab certified under the Maine DWP’s Laboratory Certification Program. This ensures quality control and standardized testing methods. Popular options include county health departments, the state health lab, university labs, and private companies like Northeast Laboratories.
3. Collect a sample
Follow the lab’s specific instructions for gathering a water sample from your tap. Special sterile bottles are usually required. Be sure to date and label the bottle and keep it sealed. Refrigerate the sample if you can’t get it to the lab right away.
4. Submit the sample to the lab
Deliver or ship your sample to the lab right after collection. Turnaround is typically 3-5 business days once received. Be sure to include the date, time, and location where the sample was taken.
5. Interpret your results
The lab will send you a detailed report on your results with an explanation of what was tested. Compare your results to state and federal drinking water standards to understand the significance of any detections. Pay special attention to contaminants that exceed the Maximum Contaminant Levels (MCLs).
Follow up with the lab, your doctor, or the Maine DWP if you have any concerns about substances detected in your water. They can help advise you on potential health risks, treatment options, and recommended actions.
How to Treat & Remove Common Water Contaminants
If your water test turns up any contaminants exceeding safe levels, don’t panic. There are treatment solutions that can remove or neutralize many types of water pollutants. Here are some options:
- Disinfection – Chlorination, UV light, and ozonation all kill dangerous pathogens.
- Water softeners – Ion exchange systems remove minerals like calcium and magnesium that contribute to hard water.
- Activated carbon filters – Absorb organic compounds, pesticides, and some heavy metals.
- Reverse osmosis – Forces water through a membrane to remove dissolved metals, salts, bacteria, and other contaminants.
- Distillation – Boils water and condenses the vapor, leaving contaminants behind. Effective but energy intensive.
- Anion exchange – Removes specific contaminants like nitrates, fluorides, and arsenic.
- Aeration – Allows gases like radon and hydrogen sulfide to escape from the water.
- pH adjustment – Calcium carbonate, sodium carbonate, or other acids/bases can adjust corrosive water to neutral pH.
Professional water treatment specialists are the best resource for identifying the optimal filtration or purification system for your specific water chemistry and issues. Be sure to retest your water after installing any treatment to ensure it’s working effectively.
How Individuals Can Help Protect Local Water
Clean water starts at the source. In addition to testing and treating water, individuals have an important role to play in keeping local rivers, lakes, and aquifers pollution-free. Here are some tips:
- Maintain septic systems properly by pumping regularly and avoiding leaks.
- Use lawn chemicals, cleaners, oils, and paints sparingly and dispose of them properly.
- Limit pesticide and fertilizer use, and don’t apply before heavy rains.
- Prevent gas, oil, and chemical leaks from vehicles, machinery, and storage tanks.
- Reduce runoff from roofs, driveways, and other hard surfaces around your home.
- Join a local watershed organization and volunteer for cleanups.
- Report any observed illegal dumping, chemical spills, or other pollution risks.
- Conserve water usage overall to limit demand on water resources.
We all live in a shared watershed, so practicing good stewardship protects the water supplies we depend on. Education is key to raising awareness on how our actions affect water quality. Spread the word on how friends and neighbors can help keep Maine waters clean.
