Water Contaminant Analysis

Understanding what's in your water is the first step to ensuring your family's health and safety. This guide explains common contaminants found in drinking water, their potential health effects, and effective methods for removing them.

Common Water Contaminants

Disinfection Byproducts (DBPs)

Common Issue Health Priority

Disinfection byproducts form when disinfectants like chlorine react with naturally occurring organic matter in water. Common DBPs include trihalomethanes (THMs) and haloacetic acids (HAAs).

Health Effects

  • Increased risk of bladder cancer
  • Reproductive issues
  • Developmental problems
  • Liver and kidney damage (long-term)

Common Sources

  • Municipal water treatment
  • Chlorinated swimming pools
  • High organic matter in water supply
  • Aging water infrastructure

Removal Methods

  • Activated carbon filtration
  • Reverse osmosis systems
  • UV treatment
  • Aeration systems

Note: The EPA limits THMs to 80 ppb and HAAs to 60 ppb in drinking water, but studies suggest health effects may occur at lower levels. Consider advanced filtration if you're concerned about these contaminants.

Heavy Metals

Health Priority Serious Concern

Heavy metals like lead, arsenic, mercury, and chromium can contaminate drinking water through industrial pollution, agricultural runoff, or older plumbing systems. Even low levels of exposure can cause serious health problems, especially in children.

Health Effects

  • Neurological damage
  • Developmental delays in children
  • Kidney and liver damage
  • Increased cancer risk
  • Cardiovascular issues

Common Sources

  • Old lead pipes and solder
  • Industrial waste discharge
  • Agricultural runoff
  • Natural deposits in groundwater
  • Mining operations

Removal Methods

  • Reverse osmosis (most effective)
  • Ion exchange filters
  • Distillation
  • Specialized media filters
  • Properly certified NSF-53 filters

Important: For lead specifically, let cold water run for 1-2 minutes before using if your home has lead pipes or was built before 1986. No level of lead is considered safe, especially for children and pregnant women.

PFAS (Per- and Polyfluoroalkyl Substances)

"Forever chemicals" used in consumer products, firefighting foam, and industrial processes. They persist in the environment and can contaminate water supplies.

Health Effects:

Increased cholesterol levels, effects on immune system, thyroid disruption, decreased fertility, developmental effects in children.

Removal Methods:

Activated carbon filtration, reverse osmosis, ion exchange resins.

Nitrates and Nitrites

These compounds enter water supplies primarily from agricultural fertilizers, animal waste, septic systems, and industrial processes.

Health Effects:

Can cause "blue baby syndrome" in infants, possible increased risk of certain cancers and thyroid conditions.

Removal Methods:

Reverse osmosis, ion exchange, distillation.

Microbiological Contaminants

Bacteria, viruses, parasites, and other microorganisms can contaminate water and cause waterborne diseases. E. coli, Giardia, and Cryptosporidium are common examples.

Health Effects:

Gastrointestinal illness, diarrhea, vomiting, cramps; can be severe in vulnerable populations.

Removal Methods:

UV disinfection, chlorination, microfiltration, reverse osmosis.

Understanding Water Testing

Water testing identifies specific contaminants and their concentration levels in your water supply. Different testing methods are used for different types of contaminants:

Laboratory Testing

Professional lab analysis provides the most comprehensive and accurate results. Samples are collected and sent to certified laboratories using EPA-approved methods.

Home Test Kits

DIY test kits can screen for common contaminants but are less accurate than lab testing. Useful for initial screening but not a replacement for professional analysis.

Continuous Monitoring

Modern systems can provide real-time monitoring of water quality parameters like pH, chlorine levels, and turbidity, alerting you to changes that might indicate contamination.

Testing Frequency

Private well owners should test annually for bacteria, nitrates, and contaminants of local concern. Municipal water users should review annual water quality reports but may want additional testing if concerned.
