## mgL Data in Aluminum WaterEffect Ratio forthe

3M Plant Effluent Diseharge Middleway West Virginia 

### May 1994 indicate thataluminum is substantially less toxic at higherpH and hardness but the effects ofpH and hardness are not well quantified atthis time 

### 2 in tests with the brook trout at low pH and hardness effects increased with increasing concentrations of total aluminumeven though the concentration of dissolved

aluminumwas constant indicating that total recoverable is a more appropriate measurement than dissolved at leastwhen particulate aluminum is primarily aluminum hydroxide particles In surface waters however the total recoverable procedure might measure aluminum associated with clay particles which might be less toxic than aluminum associated with aluminum hydroxide 

### 3 EPA is aware of field data indicating thatmany high quality waters in the

# US contain morethan 87 g aluminumI when either total recoverable or dissolved is

measured V This value was derived from data for heptachlor and the criteria document provides insufficient data to estimate the relative toxicities of heptachlorand heptachlor epoxide Y This value was derived from data for endosulfan and is most appropriately applied to the sum ofalphaendosulfan and betaendosulfan cc 

### Wien the concentration of dissolved organic carbon is elevated copper is substantially less toxic and use ofWaterEffect Ratios might be appropriate dd The selenium criteria document

## EPA440587006 September 1987 provides that if selenium is as toxic to saltwater fishes in the field as it is to freshwater fishes in the field the status ofthe fish community should be monitored whenever the concentration of seleniumexceeds

# CMC is an estimate ofthe highest concentration ofa material in surface water to which an aquatic community can be exposed briefly without resulting inan unacceptable effect The Criterion Continuous Concentration

# COG is an estimate ofthe highest concentration ofa material in surface water to which an aquatic community can be exposed indefinitely without resulting inan unacceptable effect The

## 2 Criteria

## Non Priority Pollutants 

### and Organoleptic Effects

This compilation lists all priority toxic pollutants and some non priority toxic pollutants and both human health effect arid organoleptic effect criteria issued pursuant to 

## CWA §304a Blank spaces indicate that 

### EPA has no

## CWA §304a criteria recommendations For a number ofnon priority toxic pollutants not listed 

## CWA §304a wafer +organism human health criteria are not available but

### CFR Part423 Also listed are the Chemical Abstracts Service 

### CAS registry numbers which provide a unique identification foreach chemical 

## 3 Human Health Risk

The human health criteria for the priority and non priority pollutants are based on carcinogenicity of 104 risk Alternate risk levels may be obtained by moving the decimal point

# eg for a risk level of106 move the decimal point in the recommended criterionone place to the right

## 5 Calculation of Dissolved Metals Criteria

The

### 304a criteria for metals shown as dissolved metals are calculated in one oftwo ways For freshwater metals criteria that are hardnessdependent the dissolved metal criteria were calculated using a hardness of100 mgil as

### CaCO3 for illustrative purposes only Saltwaterand freshwater metals criteria that are not hardnessdependent are calculated by multiplying the total recoverable criteria before rounding by the appropriale conversion factors The final dissolved metals criteria in the table are rounded to two sIgniffcant figures Information regarding the calculation of hardness dependent conversion factors are included in the footnotes 6 

## Maximum Contaminant Levels

The compilation Includes footnotes for pollutants with Maximum Contaminant Levels 

## MCLs more stringent than the recommended water qualitycriteria in the compilation 

### MCLs for these pollutants are not included in the compilation but can be found in the appropriate drinking water regulations

### 40CFR 1411116 and 

### 1416063 or can be accessed through the Safe Drinking Water Hotline

### 8004264791 or online 

### 7 Organooptic Effects

The compilation contains 

### 304a criteria for pollutants with toxicitybased criteria as well as nontaxicity based criteria The basis for the non toxicity based criteria are organoleptic effects

# eg taste and odor which would make waterand edible aquatic life unpalatable but not toxic tohumans The table includes criteria for organoleptic effects for23 pollutants Pollutants with organoleptic effect criteria more stringent than the criteria based on toxicity

# eg included in both the priority and non priority pollutant tables are footnoted as such
