The scientists of our accredited laboratory skillfully test water and sewage for all manner of contaminants. Since 2000, the lab team at Four Rivers Sanitation Authority has done over 60,000 tests per year in water and wastewater for solids, biological and chemical oxygen demand, cyanide, nitrogen compounds, anions, heavy metals, oil and grease, and phosphorus. We ensure your water is safe and protects human health and community water systems by using state-of-the-art equipment such as a UV/vis spectrophotometer, gas chromatograph, inductively coupled plasma mass spectrometer, ion chromatograph, and other specialized proprietary equipment.
Four Rivers Sanitation Authority’s laboratory is accredited through the National Environmental Laboratory Accreditation Program.
