Sampling and Analysis of Home Sewage Treatment Systems

Per requirements from the Ohio Environmental Protection Agency (EPA) for Home Sewage Treatment Systems, annual diagnostic sampling and analysis is mandatory to ensure the system is working properly. The annual diagnostic sampling as outlined in Ohio EPA NPDES Permit No. OHK000003 includes analysis for total suspended solids, ammonia, carbonaceous biochemical oxygen demand, dissolved oxygen, E. coli, and chlorine.
