The following is <br />a typical sampling and analysis schedule: <br />SLUDGE HOLDING TANKS <br />To represent the sludge flowing the Sludge Man- <br />agement Facility, samples are collected from the <br />sludge holding tanks' discharge line. Samples are a <br />composite of at least three grab samples taken <br />during one day. <br />pH <br />Total & Volatile Solids <br />Ammonia - N <br />Total Phosphorus <br />Kjeldahl- N <br />Nitrate + nitrite - N <br />Metals (Cd,Cr,Cu,Pb,Ni, <br />Zn,As,Se,Hg,Mo,Ag,K) <br />Total Cyandide <br />Total Phenols <br />Organic Pollutants <br />EPA 8080,8270,8240) <br />Frequency <br />weekly <br />weekly <br />weekly <br />weekly <br />weekly <br />monthly <br />quarterly <br />(3 consecutive days) <br />quarterly <br />(3 consecutive days) <br />quarterly <br />(3 consecutive days} <br />quarterly (sent to <br />commercial lab) <br />FACULTATIVE SLUDGE LAGOONS <br />WATER POLLUTION CONTROL <br />FACILITY SLUDGE LAGOON <br />Before the lagoon supernatant is decanted to the <br />treatmentplanC,eachlagoonsupernatantis sampled <br />weekly for the following tests (the sampling is <br />conducted monthly when not decanting): <br />Total Solids <br />Suspended Solids <br />pH <br />Organic Carbon <br />Ammonia - N <br />Nitrate + nitrite - N <br />
