Introduction

Why water testing
matters

Water contamination is often invisible, odorless, and tasteless. Contaminants including heavy metals, volatile organic compounds, bacteria, nitrates, and industrial chemicals can be present at dangerous concentrations without any visible sign — and standard municipal treatment does not remove all potential hazards, particularly those introduced after water leaves the treatment plant.

For properties served by private wells, the responsibility for water quality falls entirely on the property owner. For properties connected to municipal supplies, contamination can still occur through aging plumbing, lead service lines, corroded fixtures, and cross-connections — as well as through environmental contamination reaching groundwater sources used for irrigation or industrial purposes.

Ecoscope Environmental collects water samples using proper chain-of-custody protocols and submits them to a California state-certified laboratory for analysis against applicable EPA, State Water Resources Control Board, and CalEPA standards — giving you accurate, defensible results you can act on.

Many contaminants regulated by the EPA's Safe Drinking Water Act (SDWA) and California's Title 22 drinking water standards have no detectable taste, odor, or color. The only way to know whether your water is safe is to test it.

Silent Contamination Most water contaminants — including lead, arsenic, nitrates, and VOCs — are completely undetectable without laboratory testing
Private Wells at Risk Private well water is unregulated by municipal systems — owners bear full responsibility for testing and ensuring water safety
Children Most Vulnerable Lead and nitrates in drinking water are particularly harmful to infants and young children, with effects on neurological development and oxygen transport
Fast Turnaround Water sampling reports typically delivered within 5–10 business days following sample collection and laboratory analysis

Drinking Water

Potable Water Testing

Testing of drinking water from taps, wells, and municipal supplies for safety and regulatory compliance.

Environmental

Non-Potable Water Testing

Sampling of groundwater, stormwater, surface water, and process water for environmental assessment and compliance.

Regulatory

Industrial & Wastewater Testing

Discharge compliance, effluent monitoring, and industrial process water analysis for regulatory programs.

Potable water — what we test for

Lead & Heavy Metals

Testing for lead, arsenic, cadmium, chromium, copper, mercury, and other heavy metals — particularly critical in properties with older plumbing, lead service lines, or sites near historical industrial activity.

Priority Test

Bacteria & Pathogens

Total coliform, E. coli, and fecal coliform testing to assess microbiological safety — essential for private wells, post-flood assessments, and properties where distribution lines may have been compromised.

Health & Safety

Volatile Organic Compounds

Analysis for VOCs including benzene, toluene, trichloroethylene (TCE), tetrachloroethylene (PCE), and other solvents commonly associated with fuel spills, dry cleaning operations, and industrial contamination.

Chemical

Nitrates & Nitrites

Testing for nitrates and nitrites — particularly important for properties near agricultural operations, septic systems, or areas with historically elevated nitrogen loading. A leading concern for infant health.

Agricultural Areas

General Chemistry Panel

pH, hardness, turbidity, total dissolved solids (TDS), chlorine residual, sulfates, iron, manganese, and other general water quality parameters for a comprehensive baseline picture of water quality conditions.

Baseline

How it works

Potable water sampling process

Proper collection protocol is critical — sample integrity directly affects the accuracy of results.

1

Consultation

We identify the right analyte suite based on your property type, location, water source, and intended use or concern.

2

Sample Collection

Samples are collected by our field technician using proper protocols — including correct flushing procedures, sterile containers, and preservatives to maintain sample integrity.

3

Chain of Custody

All samples are documented and transported under strict chain-of-custody to a California state-certified laboratory for analysis.

4

Laboratory Analysis

Samples are analyzed using EPA-approved methods against California Title 22 and EPA Maximum Contaminant Levels (MCLs).

5

Report & Recommendations

Results are delivered in a clear report with regulatory comparisons and practical recommendations where exceedances are identified.

Non-potable water — what we test for

Groundwater Sampling

Collection and analysis of groundwater samples from monitoring wells, soil borings, and existing wells to assess dissolved contaminant concentrations — a core component of Phase II Environmental Site Assessments and site remediation monitoring programs.

Phase II / Remediation

Surface Water Sampling

Sampling of streams, drainage channels, ponds, and other surface water bodies for contamination from industrial discharge, runoff, or nearby environmental releases — supporting regulatory compliance and site characterization.

Environmental

Stormwater Sampling

Collection and analysis of stormwater runoff samples to assess pollutant loading, support NPDES permit compliance, and characterize the quality of stormwater discharging from industrial facilities, construction sites, and developed properties.

NPDES Compliance

Petroleum & LNAPL Assessment

Groundwater sampling for total petroleum hydrocarbons (TPH), BTEX compounds, and light non-aqueous phase liquids (LNAPLs) associated with underground storage tank releases, fuel spills, and pipeline leaks.

UST / Fuel Sites

Chlorinated Solvent Analysis

Testing for trichloroethylene (TCE), perchloroethylene (PCE), vinyl chloride, and related chlorinated compounds — a frequent concern at dry cleaning sites, aerospace facilities, and industrial properties throughout Southern California.

Industrial Sites
