Calculate Oregon DEQ water quality criteria for ammonia

Description

This function calculates the Oregon DEQ pH and temperature dependent ammonia criteria. Tables of values and formulas can be found at http://www.deq.state.or.us/wq/standards/docs/tables303140.pdf.

Usage

nh4Criteria(pH, Cel, toxicity = c("chronic", "acute"), salmonids = FALSE)

Arguments

pH	a water pH for the criteria
Cel	a water temperature in degrees Celsius
toxicity	the type of criteria, toxicity = 'acute' gives the acute criteria (CMC) while toxicity = 'chronic' gives the chronic criteria (CCC)
salmonids	logical, whether the criteria should be for streams with salmonid beneficial use (Table 30A). The default is FALSE. Ignored when toxicity = 'chronic'.

Details

Table 30A acute, salmonids are a designated use. Table 30b acute, salmonids are not a designated use. Table 30c chronic, fish and aquatic life are a designated use.
