Our class recently tested some local water samples - both potable (drinkable) water and water from natural sources like lakes. We would like to share our results with you here. Each sample was tested for pH (is the water acidic or basic, or hopefully neutral?), chlorine, ammonia-nitrogen (related to fertilizer pollution), salinity (salt content, which is bad for plants), turbidity (sediment content) and detergent (a product of waste water runoff).
