Domestic Water Well Testing

When selling a property with an on-site well in the State of Oregon, the Oregon Health Authority requires having the well water tested for arsenic, coliform bacteria, and nitrates.  Additional testing for lead is recommended.

Sanitary Survey

EMS will assess your well and water system for potential risks of environmental contamination, including physical damage to the system, contamination from onsite chemicals, and backflow prevention.

Hydraulic Flow Testing

To assess the capacity of a well system’s aquifer, EMS will conduct a hydraulic flow test, pumping the system at a rate of approximately five gallons a minute for four hours.  The resulting calculations and conclusions are provided within our full report.

Let EMS assist with resolving your disputes over environmental matters, property lines and easements, or compliance and regulatory issues.  We’ll provide an unbiased and accurate investigation, including depositions and court testimony as required by the case.
