CERTIFIED DRINKING WATER POTABILITY & LAB TESTING.
Know exactly what your family is drinking. EPA and TCEQ certified environmental laboratory analysis of private water wells and municipal taps: Total Coliform, E. coli bacteria, lead, nitrates, nitrites, pH, and heavy metals.


Meet Inspector Mack & The Secured Team
Every inspection is led directly by TREC Professional Master Inspectors using calibrated diagnostic gear. We don't just check cosmetic boxes—we map subgrade foundation movement, scan thermal anomalies through solid sheetrock, and scope subterranean lateral lines to defend your earnest money and equity.

Drinking Water Safety: Coliform, Lead & Agricultural Nitrates
Inspector Mack explains the critical health parameters tested in private Texas wells and how sterile laboratory collection protects your health.
"Clear, sparkling water can still be loaded with dangerous E. coli bacteria or invisible toxic nitrates from nearby cattle ranches. Never guess about drinking water safety—always verify with an accredited laboratory."
WHAT WE SPECIFICALLY AUDIT & DELIVER
Our forensic checklist exceeds standard minimum requirements. Every component is rigorously evaluated and cataloged with high-resolution imagery and severity tiers:
Total Coliform & E. coli Microbial Analysis
Sterile laboratory culturing verifying 0 CFU/100mL presence of sewage-borne and soil-borne fecal bacteria.
Nitrates & Nitrites (Fertilizer Runoff)
Testing parts per million (ppm) of nitrate nitrogen (MCL 10 mg/L) to prevent infant methemoglobinemia.
Lead & Copper Heavy Metal Testing
Laboratory testing verifying lead is below the EPA Action Level of 15 parts per billion (ppb) and copper below 1.3 ppm.
Total Dissolved Solids (TDS) & Mineral Hardness
Measuring calcium/magnesium hardness grains per gallon (GPG) and total dissolved minerals affecting pipes and appliances.
pH Acidity & Corrosivity Index
Testing water pH balance (6.5 to 8.5 target) to identify acidic water that dissolves copper plumbing pipes.
Turbidity & Sediment Analysis
Measuring Nephelometric Turbidity Units (NTU) to detect suspended clays, sand, or silt from well screens.
Sterile Chain-of-Custody Sampling Procedure
Removing faucet aerators, flaming/disinfecting tap spouts, running 10-minute flush, and sealing in sterile sodium thiosulfate bottles.
Certified State Environmental Lab Report
Delivery of official laboratory Certificate of Analysis with clear benchmark comparisons against EPA Maximum Contaminant Levels.
Texas Gulf Coast Environmental Defect Matrix
Southeast Texas structures face unique environmental stressors that generic national inspection checklists routinely overlook. We specialize in identifying these regional failure modes:
Positive Total Coliform and E. coli Bacteria
Surface runoff or failing septic tank effluent penetrating unsealed well casing, contaminating the drinking water supply.
Elevated Nitrates Above EPA 10 mg/L Threshold
Agricultural fertilizer or cattle manure leaching into shallow aquifers near rural homesteads.
Acidic Water (pH < 6.2) Leaching Toxic Copper & Lead
Naturally acidic groundwater dissolving internal copper pipe walls and lead solder joints inside household plumbing.
Advanced Diagnostic Equipment Suite
Human eyes alone miss hidden electrical hotspots, subterranean pipe collapses, and millimeter-level slab deflections. Every Secured Inspections vehicle is equipped with industrial instrumentation:
EPA-Approved Sterile Sample Collection Bottles
Preserved with sodium thiosulfate to neutralize residual halogens, shipped in temperature-controlled cooler boxes.
Digital Multi-Parameter Water Quality Meter
Field testing temperature, pH, electrical conductivity, and total dissolved solids (TDS) directly at the tap.
High-Sensitivity Free Chlorine Test Meter
Verifies zero chlorine residual to ensure seller has not artificially masked well bacteria with bleach.
NELAP/TCEQ Accredited Environmental Laboratory
Full ICP-MS mass spectrometry and automated bacterial incubation testing.
Actual Field Finding & Financial Impact
Here is an authentic defect documented in our recent inspections, demonstrating how our forensic reports deliver tangible financial leverage:
Positive E. coli Bacteria & Elevated Lead (18 ppb)
Our certified laboratory testing returned a positive result for E. coli bacteria (12 CFU/100mL) and lead levels at 18 ppb (exceeding the EPA 15 ppb action level). The water was unsafe for human consumption, and the buyer's VA mortgage was suspended pending remediation.
Frequently Asked Questions: Drinking Water Quality Lab Testing
Everything you need to know about this inspection scope, scheduling timeline, and Texas legal protections:
Q1Why should I test private well water before buying?▼
Unlike municipal city water, private well water is not regulated or tested by any government authority. As the property owner, you are 100% responsible for verifying that your well water is free of toxic bacteria, lead, and hazardous agricultural chemicals.
Q2What does the standard drinking water potability panel test?▼
Our standard potability panel tests for Total Coliform bacteria, E. coli bacteria, Lead, Nitrates, Nitrites, Total Dissolved Solids (TDS), and pH. This satisfies all standard VA, FHA, and conventional mortgage underwriting requirements.
Q3What does 'Total Coliform Positive' mean?▼
Coliform bacteria are indicator organisms found in soil, plants, and animal waste. While not all coliforms cause disease, their presence proves that surface contaminants are entering your well, meaning disease-causing pathogens like E. coli may also be present.
Q4How long do laboratory water results take?▼
Because biological bacteria require a 24-hour incubation period in the laboratory, official water potability reports are typically completed within 48 to 72 business hours after sample collection.
Q5What should I do if my water test fails?▼
If bacteria is detected, the well must undergo professional shock chlorination and a new sanitary wellhead cap should be installed. If chemical contaminants like lead or nitrates are high, whole-home filtration or reverse osmosis systems are required.
Q6Can I test water in a home connected to city water?▼
Yes. While city water is treated at the municipal plant, it travels through aging city distribution mains and older home plumbing pipes that may contain lead solder, copper leaching, or heavy chlorine disinfection byproducts.
