The break up of parallel elements is as follows,
various causes,
including seepage from septic fields, ---- Simple Gerund phrase as Nouns
overuse of waterways by boats lacking proper waste disposal facilities,
--- Noun phrase
spraying indiscriminate pesticides by farmers, -- Simple Gerund phrase as Nouns
The correct usage is,
