cost, With the possible exception of the vehicle, should be eligible 
for 75% Construction Grant funding if needed for POTW Pretreatment Program 
development. This is not totally consistent with other guidelines in 
the Construction Grants program, however, in which special purpose vehicles 
integral to the operation of a Federally funded treatment works are grant 
eligible on a one-time basis. Certainly, vehicles used in a POTW sampling 
program are an integraland necessary part of a Federally funded treatment 
works. 
Lab Analyses 
It can be safely assumed that nearly all POTWs have some laboratory 
capability in order to meet the needs of plant. operation and NPDES reporting. 
Initiation of a POTW Pretreatment Program in accordance with U.S. EPA 
regulations will generally necessitate the addition of laboratory equipment 
and personnel. [In addition, it may require the acquisition of additional . 
laboratory space. Ihe laboratory equipment required for a municipal 
wastewater treatment plant is generally standard. If there is a significant 
amount of industrial waste received by the facility, specialized equipment 
may be necessary. 
Probably the most significant instrument for the determination of 
metals in water is the atomic absorption spectrophotometer (A.A.). There 
are more than thirty elements that can be analyzed by atomic absorption. 
According to the EPA publication titled Handbook for Analytical Quality 
Control in Water & Wastewater Laboratories, an experienced analyst can 
perform 150 analyses per day when no preliminary treatment of the sample 
is necessary. This number drops down to 60-80 per day when the metals 
analysis is performed following preliminary treatment of the samples. 
Consequently, if each sample were to be analyzed for 20 elements, the 
number of samples analyzed daily would be in the range of from three 
to seven. Figure 5-2 indicates that the cost of a good A.A. is in the 
order of $50,000. Supplies for the A.A. are approximately $3,000 per 
year. The cost of a qualified operator is assumed to range from $16,000 
to $22,000 per year. 
The normal methods for measucing organics in wastewater (BOD, TOC, 
and COD} do not provide any information on the molecular structure and 
quantity of a particular organic molecule. In order for a POTW to adequately 
administer an EPA approved pretreatment program, such capability will 
Probably be necessary. 
For these type of analyses, EPA recommends the use of a Gas chromato- 
8taph-Mass Spectrometer (GC-MS). Figure 5-2 indicates that a moderately 
Sized GC-MS meeting EPA protocols costs approximately $120,000. Accessories 
and glassware cost approximately $5,000, and a year's supply of chemicals 
Can be assumed to cost approximately $15,000. Based on four samples 
Per day and 200 productive workdays, a GC-MS of the type noted above 
Could handle approximately 800 samples per year. On each sample, as 
many as 120 compounds can be measured. Since the number may increase 
in the future, the computer associated with the GC-MS system has the 
Capability to identify literally thousands of compounds.
