Water
Testing & Sampling
Professional potable and non-potable water sampling and laboratory analysis to identify chemical, biological, and heavy metal contaminants — protecting occupants, workers, and property owners throughout Southern California.
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.
Potable Water Testing
Testing of drinking water from taps, wells, and municipal supplies for safety and regulatory compliance.
Non-Potable Water Testing
Sampling of groundwater, stormwater, surface water, and process water for environmental assessment and compliance.
Industrial & Wastewater Testing
Discharge compliance, effluent monitoring, and industrial process water analysis for regulatory programs.
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 TestBacteria & 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 & SafetyVolatile 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.
ChemicalNitrates & 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 AreasGeneral 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.
BaselineReal Estate & Well Water Panel
Comprehensive drinking water panel designed for property transactions and private well assessments — covering bacteria, metals, VOCs, nitrates, and general chemistry in a single sampling event to support due diligence and disclosure.
TransactionsHow it works
Potable water sampling process
Proper collection protocol is critical — sample integrity directly affects the accuracy of results.
Consultation
We identify the right analyte suite based on your property type, location, water source, and intended use or concern.
Sample Collection
Samples are collected by our field technician using proper protocols — including correct flushing procedures, sterile containers, and preservatives to maintain sample integrity.
Chain of Custody
All samples are documented and transported under strict chain-of-custody to a California state-certified laboratory for analysis.
Laboratory Analysis
Samples are analyzed using EPA-approved methods against California Title 22 and EPA Maximum Contaminant Levels (MCLs).
Report & Recommendations
Results are delivered in a clear report with regulatory comparisons and practical recommendations where exceedances are identified.
Potable water testing deliverables

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 / RemediationSurface 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.
