Groundwater Treatment System Design Manuals 1

[trl2008]

I'm am looking for groundwater treatment system (ie: Air Sparge/SVE, free product recovery, air stripping etc.) design manuals.

What I'm looking for is guidance such as how to conduct a pilot test, what to measure during a pilot test, how to size equipment, what type of piping to use etc. etc. A guidance document with steps and procedures from start to finnish on how to perform designs for various sytems would great.

I'm just starting out designing systems and don't really have any good refernece manuals except for text books which aren't helpful. I've search Amazon.com and the internet but can't really find what I'm looking for.

There may not be much, but try the Corps of Engineers or AFCEE.

I assume you want to collect data to capture groundwater/free product and use to design some type of treatment system for vapor/liquid treatment with groundwater capture.

I have some experience with designing dual phase extraction remediation systems.

What are the contaminants of concern etc..?

Thanks lamojaj, In regards to your question, I'm currently working on a couple of petroleum contaminated sites. Thus, the chemicals of concern are BTEXs, MTBE, lead etc.

You want to plan and implement a pumping test to determine the extent of capture that you can anticipate with your groundwater extraction wells. This will allow you to determine the spacing and numbers of wells. The number and spacing of wells is based on the extent of contamination and to a certain extent an economic decision. Also determine the location of monitoring wells surrounding the pumping well during test, new or existing, will allow you to determine the extent of capture during the pumping test.

Taking groundwater samples during the test will allow you to determine the basis of design for treatment, extent of treatment etc. Any free product found? Depending on the influent, captured groundwater concentration, this will drive the extent and type of treatment. So will the effluent limits post treatment. Try air stripping as a start for treating groundwater contaminated with BTEX. Try Freeze and Cherry's "Groundwater" to see an explaination of a pumping test.
