The data presented here was collected at Prado Wetlands in Riverside County, CA, USA. Physical water column parameters were collected using a multprobe sonde and includes date and time of sample collection, location (inlet, outlet), temperature (degrees Celsius), pH, specific conductivity (mircoSiemens per centimeter), and dissolved oxygen (milligrams per liter). An ISCO autosampler was utilized to remotely collect diel water samples at the inlet and outlet of the wetland. These samples were analyzed for dissolved metals (aluminum, arsenic, boron, barium, beryllium, bismuth, bromine, calcium, cadmium, cerium, cobalt, chromium, copper, dysprosium, erbium, europium, iron, gallium, gadolinium, holmium, potassium, lanthanum, lithium, lutetium, magnesium, manganese, molybdenum, sodium, neodymium, nickel, phosphorus, lead, praseodymium, rhodium, sulfur, antimony, selenium, silicon dioxide, samarium, strontium, terbium, tellurium, thorium, thallium, thulium, uranium, vanadium, yttrium, ytterbium, and zinc all reported in milligrams or micrograms per liter), chloride (micromolar), nitrite (micromolar), nitrate (micromolar), phosphate (micromolar), sulfate (micromolar), sodium (micromolar), ammonium (micromolar), potassium (micromolar), magnesium (micromolar), calcium (micromolar) alkalinity (milligrams per liter as bicarbonate), and dissolved methane (micromolar). Porewater samples were collected using an array of Henry samplers (configuration described in Duff et al. 1998). Samples were analyzed for nitrite (micromolar), nitrate (micromolar), sodium (micromolar), ammonium (micromolar), potassium (micromolar), magnesium (micromolar), and calcium (micromolar).
