(d) Other specific needs are met on a particular 

 problem basis. 



The general characteristics of the minimum monitoring program are 

 described below: 



(2) Sampling : All samples (except for grab samples col- 

 lected for special analyses for high decay rate constituents) 

 collected for routine analysis should be near-continuous, 

 proportional composite samples which accurately represent 

 the characteristics of the waste stream (i.e., floatable, 

 suspended, and dissolved constituents) with respect to their 

 true mass emission rates (I.e., lbs/day). 



Sufficient samples should be collected to provide an ade- 

 quate statistical description for both the constituent con- 

 centration and the mass emission rate of the contaminant. 

 After the waste has been statistically defined, analyses 

 not pertinent to the local problem or to the wastes char- 

 acterization should be deleted. 



(3) Analyses : The following analyses should be conducted 

 on essentially all samples colledted: 



(a) Floatable matter - Method needs development 



(b) Total and Organic - Methods Adequate 

 Suspended Solid 



(c) Acute Toxicity - Method needs review
