Spatial distribution of the development is extremely important for water quality in the estuary. Even more important are the particular land use practices. Grow trees, not lawns. Yet more important are the management practices. The redesign of septic fields, that would deliver the effluent to the root zone, rather than the groundwater, can considerably increase nitrogen retention and improve the water quality of the estuaries.
Recommendations Support further analysis of the pathways of nutrients across the watershed.
Consider alternative designs of septic tanks and drainage fields, that would make more use of biological treatment. Prioritize and implement conservation efforts before further growth outstrips their positive effects. Minimize clearing, maximize reforestation and encourage reduced lawn areas.
