Pretreatment coordinators use computers, printers, e-mail, the Internet, spreadsheets, and word processing programs to perform their duties under the pretreatment program.

The laboratory staff work cooperatively with the Water Pollution Control Facility maintenance staff to perform required pretreatment sampling. The laboratory maintains several automatic samplers that can be configured to gather either timed or flow-proportional samples. The laboratory uses chain-of-custody documentation to track sample progress.

The laboratory is equipped and certified to perform most of the analyses needed for the pretreatment program. Analyses performed by the Water and Pollution Control Laboratory include the following:

Total Dissolved Solids	Total Suspended Solids	Temperature
Chloride	Total Chlorine	Fecal Coliform
Total Coliform	Conductivity	Cyanide
Ammonia-N	Nitrate+Nitrite-N	TKN
CBOD5	COD	Dissolved Oxygen
Phenol	Total Phosphorus	Arsenic
Barium	Cadmium	Chromium
Copper	Iron	Lead
Manganese	Mercury	Molybdenum
Nickel	Potassium	Selenium
Silver	pH	Zinc

Other regularly analyzed parameters are analyzed by outside contract laboratories. Some of these parameters include, but are not limited to, the following:

Oil and Grease	Sulfide	Antimony
Berylium	Calcium	Cobalt
Magnesium	Sodium	Thallium
Tin	Titanium	Vanadium
Acetone	BTEX	Radiologicals
Total Extractable Hydrocarbons
Total Petroleum Hydrocarbons
Other Priority Pollutant Parameters
TCLP Parameters

The City of Ames Non-Domestic Waste Pretreatment Program is funded through regular community sewer billing, although non-domestic pretreatment facilities are billed for the costs of sampling and analyzing for their facilities.
