Water Quality
Information Session – Balls FallsJanuary 27, 2016
1) Assess water quality:
• Surface water quality • Groundwater quality
2) Report water quality:
• Annual Water quality Reports
• Watershed Report Card
• NPCA Web Site
NPCA Water Quality Monitoring Program was implemented in 2001 with a mandate
to:
NPCA monitors 74 Surface Water Stations and 15 Groundwater Stations.
Indicator Sources ImpactsChloride Road salt, sewage Ecological toxicity
Phosphorus Fertilizers, sewage Excess algae growth
Nitrate Septic systems, fertilizers Human health
Suspended Solids
Erosion, urban and agricultural runoff
Degraded aquatic habitat
E. coli Sewage, manure Beach closures, boil water advisories
Metals Industrial effluents, pesticides, storm water

There are two chronic water quality issues:
BioMAP Water Quality Index
Biological Data Analysis
NPCA Groundwater Monitoring
What is the groundwater data telling us?
• Water quality at most NPCA wells meets Ontario Drinking Water Guidelines.
• Those parameters exceeding the Guidelines (i.e. fluoride, sodium) are attributed to natural contact with local bedrock.
• Identify ‘Target Areas’• Are we successful?
