Shark River Slough TP Concentration Compliance Tracking

(October 2015–September 2016 Flow Data are Provisional)

Shark River Slough PROVISIONAL RESULTS: Method 1 (left values) computed as S12s+(S333-S334) and Method 2 (right values) computed as S12s+(S333-S334)+S355A+S355B+S356 using all flow and TP grabs on bi-weekly compliance sampling dates.
