Having access to clean, safe drinking water is one of the most basic human needs. Yet many communities struggle to provide consistent, high-quality water to their residents. That’s why regular water quality testing is absolutely vital for any municipality or water provider.
The Importance of Water Quality
Clean water is essential for public health. Contaminated water can transmit diseases like cholera, dysentery, typhoid and polio. Even in developed countries, waterborne illnesses affect millions each year. Beyond disease prevention, water quality impacts things like:
- Physical health – Poor water quality can cause gastrointestinal issues, reproductive problems, neurological disorders and more.
- Child development – Contaminants like lead and mercury can impair childhood development.
- Local ecosystems – Pollution harms wildlife habitats and biodiversity.
- Agriculture and fishing – Contaminants reduce crop yields and the health of fish stocks.
- Local economies – Water pollution clean-up efforts can cost millions. Safe water helps sustain businesses.
Water Quality Testing allows providers to monitor for contaminants, detect emerging issues early and take corrective action when needed. Robust testing programs are the only way to truly understand water conditions and risks.
Common Water Contaminants
Many types of contaminants can infiltrate water sources and end up coming through the tap. Here are some of the most concerning:
Microbial Contaminants
- Bacteria – E. coli, coliform bacteria
- Viruses – rotavirus, hepatitis A
- Parasites – Giardia, Cryptosporidium
These microbes often originate from human or animal waste. They can cause severe gastrointestinal illness.
Inorganic Contaminants
- Lead
- Arsenic
- Mercury
- Nitrates/Nitrites
Inorganic contaminants leach into groundwater from natural deposits or industrial processes. They are linked to cancer, organ damage and other serious health effects.
Organic Contaminants
- Pesticides
- Industrial chemicals
- Petroleum byproducts
Man-made organic chemicals make their way into water through agricultural and industrial activities. They pose reproductive, neurological and cancer risks.
Radiological Contaminants
- Radon
- Uranium
- Radium
Radiological elements naturally occur in some groundwater. They are carcinogenic and radioactive.
Water Quality Testing tracks the levels of these and other concerning contaminants. With constant vigilance, problems can be detected early and addressed.
How Often to Test Water Quality
Water Quality Testing should be performed frequently and consistently. Testing schedules vary based on water source and provider size.
Municipal Water Suppliers
Most cities and towns test water quality multiple times per day. State and federal laws regulate standards:
- Source water – Tested quarterly or annually
- Treatment plants – Tested continually
- Distribution system – Tested regularly from representative sites
Frequent testing allows providers to confirm processes are working and water is safe as it travels to end users.
Private Wells
Homeowners with private wells are responsible for their own water quality testing. Experts recommend:
- Annual testing for bacteria and nitrates
- Every 3-5 years for inorganic contaminants
- Every 10 years for pesticides, radon and other chemicals
More frequent testing provides peace of mind and helps catch intermittent issues.
Times to Retest
Additional water quality testing is advisable when:
- Household plumbing changes are made
- Nearby land use changes occur – like new construction or industry
- Pipes are repaired or replaced
- Family members become pregnant or immunocompromised
- There is a change in water taste, smell or appearance
Water Quality Test Parameters
Water Quality Testing involves analyzing samples for many different contaminants. Common parameters include:
Microbes
- Total coliform bacteria
- E. coli
- Heterotrophic plate count – other bacteria
- Giardia and Cryptosporidium
Metals
- Lead
- Copper
- Arsenic
- Mercury
- Manganese
- Chromium
- Cadmium
Inorganic Chemicals
- Nitrates and nitrites
- Fluoride
- Chloride
- Sulfate
Organic Chemicals
- Volatile organic compounds (VOCs) – fuels, solvents
- Synthetic organic compounds (SOCs) – pesticides, chemicals
- Trihalomethanes (THMs) – chlorination byproducts
Radiological Chemicals
- Radon
- Gross alpha radiation
- Uranium
General Parameters
- pH
- Total dissolved solids (TDS)
- Corrosivity
- Alkalinity
This covers the major contaminant categories. Specific risks in the region may require testing for additional chemicals like perchlorate, MTBE and more.
A thorough Water Quality Testing panel provides a complete contaminant profile. Both government and private labs can perform these analyses.
How Water Quality is Tested
Professional water quality testing involves specialized techniques and expert analysis. Here is an overview:
Sampling
- Samples are collected from taps after water sits unused overnight to capture potential contaminants.
- Special bottles provided by the lab are filled per instructions.
- Detailed notes are taken about sampling points and conditions.
Analysis
- Bottles are shipped to an accredited lab for analysis.
- Contaminant levels are measured using methods like liquid chromatography, mass spectrometry, cell culturing, colorimetry, atomic absorption and more.
- Careful quality control ensures accurate, precise results.
Interpretation
- Levels of each contaminant are compared to regulatory and health-based standards.
- An expert reviews the full results profile to identify potential health risks.
- Issues of concern trigger follow-up testing and investigation of causes.
Proper protocols ensure testing provides meaningful, actionable data about water quality.
Addressing Water Quality Problems
When water quality testing reveals contaminant levels above acceptable limits, swift action must be taken:
Notify Users
- Consumers have a right to know about water quality issues that could impact their health.
- Public notices allow individuals to take precautions like using alternative water sources.
Investigate the Source
- Understanding where contaminants originate is key to addressing them.
- Sources may include treatment failures, environmental pollution, or issues with plumbing and fixtures.
Implement Solutions
- Contamination root causes dictate the needed solutions.
- Options include optimizing treatment, reducing pollution, replacing pipes, or deeper remediation.
Retest
- Follow-up testing confirms when corrective actions successfully reduce contaminant levels.
- Ongoing monitoring ensures problems do not recur.
Responding quickly when testing indicates water quality issues limits consumer exposure and prevents small problems from becoming serious risks.
