Field Measurements include: Dissolved Oxygen, Temperature, Conductivity and pH. Nutrients include Ammonia as N, Nitrate/Nitrite as N, Total Kjeldahl Nitrogen as N, and Total Phosphorus as P. No requirements for metals monitoring are included in the current MOA, as the DWQ is currently in the process of reviewing metals water quality assessment techniques, evaluation criteria and relevant standards.
Frequency: “M”=Monthly; “M+2SM”=Monthly with Twice Monthly Summer Sampling in May, June, July, August, and September. Samples are collected at least ten days apart except when extenuating circumstances arise such as inclement weather or other emergency situations.
