Mayfield Environmental Solutions is an MBE/DBE General Contractor in California with decades of experience in environmental analysis in the most toxic environments, ranging from fire disasters to Superfunds/CRCLA to sensitive wetlands and waterways.
Whether residential, commercial, or industrial, we can test your water and provide certified 3rd-party laboratory analysis for all major contaminants and “built environment” inspections, including Lead, Chlorine, Mercury, Nitrates/Nitrites, Perchlorate, eColi (Total Coliform), Legionella, Radon Gas, Microplastics, Naturally-Occurring Radioactive Materials, Pesticides, Beryllium, pH, Turbidity, TSS (Total Suspended Solids), TMDL/NAL discharge limit exceedances, Heavy Metals, and PFAS (“Forever Chemicals”) which are under new scrutiny and regulation in California. We will get your test results back to you with a certified Chain of Custody with our professional interpretation to keep you compliant.
As part of our work with the California Wildfire Disaster Zones, we also do clearance testing for boil water advisory alerts and for combustion byproducts to ensure your water is safe for human consumption.
We are also experts in Legionella, a sensitive requirement of the California Department of Public Health, CDC, and GSA for all public facilities. This includes water sampling for Legionella using either PCR testing or traditional spread-plate method (the CDC standard), and lab culture growth counting with serotyping. We will provide a certified Chain of Custody (COC) and full analytical report back to you as soon as our 3rd-party lab results are available. If Legionella is detected, we will help you with Legionella mitigation and remediation to prevent a further outbreak of public health risks. This includes filtration systems, general health and safety changes, and even Ultraviolent Germicidal Irradiation (UGI).
Our Public Works, Federal, and Tribal (SAM/GSA/8A-Set Aside) licensing allows us to perform more comprehensive water quality testing than our competitors, including on federal facilities and for GSA-leased facilities. We also have all licenses related to Water Board compliance, including QSD, QSP, QISP, and more — which lets us provide the expertise needed to keep your Stormwater and Watershed Management Plans compliant with the Construction General Permit (CGP) and more.
