Donovan's Water Testing Services

 

Basic Water Quality Analysis

We perform complete on-site testing during any scheduled technician visit to your home. Our certified technicians use professional-grade digital equipment to measure multiple water quality parameters simultaneously.

The entire process takes less than 5 minutes, and you receive a detailed water quality test report before we leave your property.

Specialized Laboratory Testing

When standard test results indicate concern or you have specific questions about contaminants like lead, PFAS, coliform bacteria, or volatile organic compounds, we coordinate specialized lab analysis.

This testing requires a technician equipped with proper lab test kits and involves additional fees. Lab testing provides detection at parts-per-trillion levels for substances that on-site equipment cannot measure accurately.

Contaminates We Test for in Your Water Supply

Donovan thoroughly analyzes your water to detect a wide range of contaminants that can affect your health and home. From common minerals to harmful bacteria and chemicals, our comprehensive testing ensures you know exactly what’s in your drinking water.

Hardness (Calcium & Magnesium)

Identifies scale buildup risk that affects appliances, plumbing, skin, and hair by measuring the concentration of calcium and magnesium minerals in your water. High levels of these minerals, commonly referred to as water hardness, can lead to the formation of scale deposits inside pipes and on fixtures, reducing water flow and efficiency.

This buildup not only shortens the lifespan of appliances like water heaters and dishwashers but can also cause dryness and irritation to skin and hair during daily use. Understanding hardness levels helps determine the need for water softening treatments to protect both your home’s plumbing system and your family’s comfort.

Total Dissolved Solids (TDS)

Measures combined minerals, salts, and metals that impact taste and overall water safety. Total dissolved solids include a variety of substances such as calcium, sodium, magnesium, potassium, bicarbonates, chlorides, and sulfates.

Elevated levels of TDS can affect the taste, odor, and clarity of your water, often resulting in a salty, bitter, or metallic flavor. High TDS levels may also indicate the presence of harmful contaminants or excessive minerals that can lead to scaling in pipes and appliances, reducing their efficiency and lifespan.

Chlorine & Chloramine

These disinfectants, primarily chlorine and chloramine, are essential for killing harmful bacteria and viruses in public drinking water supplies, ensuring regulatory compliance with safety standards.

However, their presence can lead to noticeable effects such as a distinct chemical taste and odor in tap water, as well as skin and hair dryness during consumption and daily use. Monitoring the levels of these disinfectants helps balance effective microbial control with minimizing unpleasant sensory impacts.

Additionally, excessive disinfectant concentrations can react with organic matter in water to form disinfection byproducts, some of which may pose health risks over long-term exposure. Our water quality testing evaluates these concentrations to recommend appropriate treatment solutions.

pH Level

Assesses whether water is acidic or alkaline, which impacts pipe corrosion and drinking water taste. The pH level is a crucial indicator of water quality because water that is too acidic (low pH) can corrode metal pipes, leading to the leaching of harmful metals such as lead and copper into your drinking water.

On the other hand, water that is too alkaline (high pH) can cause scale buildup, resulting in cloudy water and potential damage to plumbing fixtures and appliances. Maintaining a balanced pH level, around 6.5, helps ensure the safety, taste, and longevity of your water system.

Iron

Elevated iron concentrations in water can lead to significant aesthetic and functional problems in your home. Apart from the characteristic orange or reddish-brown stains, high iron levels may cause unpleasant metallic tastes and odors in your drinking water.

Over time, iron deposits can accumulate inside plumbing systems and appliances, reducing water flow and efficiency. This buildup can also promote the growth of iron bacteria, which form slimy coatings and cause foul odors, further compromising water quality.

Detecting and managing iron levels is essential not only for maintaining the appearance of your fixtures and laundry but also for preserving the longevity and performance of your home's plumbing.

Additional Contaminants (Upon Request)

Lead, total coliform bacteria, E. coli, PFAS, nitrates, and other heavy metals can be tested through lab analysis when specifically necessary.

Understanding Northeast Florida's Water Quality

Throughout the Greater Jacksonville area—from Atlantic Beach and Neptune Beach to St. Augustine, Orange Park, Fleming Island, and Ponte Vedra—our water comes from the Floridan Aquifer, located about 1,000 feet underground. While local water utilities work hard to meet EPA standards, homeowners across Duval, Clay, St. Johns, and Nassau Counties face several water quality challenges unique to our region:

Hard Water with High Mineral Content: Northeast Florida has some of the hardest water in the state. The limestone aquifer naturally adds calcium, magnesium, and sulfates to our water—which is why residents in Jacksonville Beach, Mandarin, Southside, and throughout the First Coast see white scale on faucets and cloudy ice cubes.

Do You Know What's In Your Water

Our Water Quality Testing Process

1

Sample Collection

Our certified technician collects water samples using proper techniques during your scheduled visit. Correct sampling methods ensure accurate results that reflect your actual water quality.

All findings are recorded in a comprehensive water quality test report. The report details measured values compared against Environmental Protection Agency’s standards, clearly flagging any parameters that exceed recommended levels.

4

Treatment Recommendations

Based on your specific test results, we provide customized recommendations for water treatment solutions. Whether you need a water softener for hardness, carbon filtration for chlorine removal, or reverse osmosis for safe drinking water, our guidance addresses your exact water quality challenges.

Why Water Quality Testing is Essential for Your Home

Your drinking water travels through miles of aging pipes before reaching your tap, picking up minerals, chemicals, and other contaminants along the way.

Professional water testing identifies exactly what’s in your water supply so you can address problems before they affect your health or damage your home.

  • Protects Your Investment. Hard water causes scale buildup that reduces appliance efficiency by up to 30% and shortens the lifespan of water heaters, dishwashers, and washing machines.
  • Safeguards Family Health. Undetected contaminants like lead, heavy metals, and bacteria can pose serious health risks, especially for children and elderly family members.
  • Prevents Costly Damage. Iron in water creates stubborn orange stains in sinks, tubs, and laundry that are difficult or impossible to remove.
  • Improves Daily Comfort. Chlorine and chloramines added by municipal treatment can dry out skin and hair while leaving an unpleasant taste and odor in your tap water.
  • Guides Effective Treatment. Test results provide the foundation for recommending water softeners, filtration systems, or reverse osmosis solutions tailored to your specific water quality issues.

Expected Results After Water Treatment Installation

Professional water treatment equipment delivers measurable improvements in your water quality:

  • Hardness reduced to near zero levels, eliminating scale buildup and improving soap lathering
  • Chlorine & chloramine nearly undetectable after carbon filtration, removing chemical taste and odor
  • Iron completely eliminated from your water supply, preventing staining throughout your home
  • pH Level properly balanced between 6.5-7 for optimal water quality and reduced pipe corrosion
  • Total dissolved solids decreased by 90-99% with reverse osmosis, delivering cleaner, better-tasting drinking water

Safe drinking water is our top priority for you and your family. For this reason, we always recommend installing a reverse osmosis filtration system.

Reverse osmosis filtration removes up to 90+ contaminants including lead, bacteria, pesticides, and other chemicals. We can help you with filter installation too!
