Trusted Drinking Water Testing Experts

Olympian Water Testing is a trusted provider of drinking water analysis services. Our testing process follows strict laboratory standards to ensure accurate results and dependable reporting. Water contamination can occur from aging plumbing systems, environmental pollutants, or infrastructure issues. Professional water testing helps identify these problems early and ensures that drinking water remains safe for everyday use. Our services provide clear laboratory results and recommendations to help improve water quality if contaminants are detected.

Lead Water Testing for Safe Drinking Water

Lead contamination in drinking water is a serious health concern. Older plumbing systems, pipes, and fixtures can introduce lead into tap water over time.

Olympian Water Testing provides professional lead water testing using certified laboratory analysis to detect even trace levels of lead contamination.

Why Lead Testing Is Important

Lead exposure can pose health risks, especially through drinking water. Regular testing helps identify potential contamination and ensures water safety.

Our testing services provide:

Accurate laboratory lead analysis
Professional water sample collection
Reliable detection of lead levels
Detailed reporting and interpretation

Testing for lead in drinking water provides peace of mind and helps ensure that your water meets recommended safety guidelines.

Common Contaminants Found in Drinking Water

Water testing can identify a range of contaminants that may affect water safety or taste.

Heavy Metals

Testing for metals that may enter water through plumbing systems or environmental sources.

Chemical Contaminants

Laboratory analysis detects chemicals that may affect water quality and safety.

Bacteria and Microorganisms

Testing identifies bacteria that may be present in drinking water supplies.

General Water Quality Indicators

Laboratory testing evaluates indicators such as pH levels, mineral content, and overall water composition.

Comprehensive water testing provides a complete picture of your water quality and helps identify potential issues before they become serious problems.

BUILDING ERA RISK PROFILE

LEAD RISK BY BUILDING CONSTRUCTION ERA

PRE-1940

Highest Risk

Galvanized steel service connections, lead-tin solder throughout, possible lead service lines. First-draw sampling at multiple fixtures provides comprehensive characterization.

1940–1986

High Risk

Copper plumbing with lead-tin solder at every joint. The 1986 ban reduced but did not eliminate this risk. Any pre-1986 copper building warrants first-draw testing.

1986–2014

Moderate Risk

Lead-free solder standard. Brass faucets may still contain up to 8% lead. Low-use fixtures can still show elevated first-draw concentrations from brass fixture leaching.

POST-2014

Lower Risk

NSF/ANSI 61 “lead-free” fixtures require <0.25% lead. Lead solder and lead service lines no longer permitted. Primary concerns shift to PFAS and distribution chemistry.

Professional Water Sample Collection and Laboratory Analysis

Accurate water testing begins with proper sample collection. Our trained specialists collect water samples using professional procedures to ensure reliable results.

Samples are then analyzed by certified laboratories using advanced testing methods to detect contaminants at very low levels.

Our testing process includes:

Professional water sample collection
Certified laboratory analysis
Accurate contaminant detection
Clear and detailed reporting

This process ensures dependable results and provides the information needed to evaluate drinking water quality.

TESTING SERVICES

CERTIFIED LEAD TESTING FOR EVERY PROPERTY TYPE AND REGULATORY NEED

FIRST-DRAW LEAD TESTING

Standard residential first-draw sampling at kitchen sink cold tap — collected before any morning flushing after a minimum 6-hour stagnation period. EPA-recommended protocol for detecting building-side lead exposure.

Residential

SEQUENTIAL DRAW (3TS)

Multi-draw sampling at each fixture: first draw captures branch line, subsequent draws capture riser and distribution contribution. Required for school and childcare compliance under EPA 3Ts.

Schools

BUILDING-WIDE ASSESSMENT

Multi-point sampling across representative fixtures throughout a building — ideal for property managers and owners seeking full lead characterization before disclosure or remediation planning.

Commercial

POST-REMEDIATION VERIFICATION

After pipe replacement or filtration upgrades, certified sampling confirms lead levels meet safety targets before occupants resume normal water use. Includes compliance-ready documentation.
