The Chicago Park District maintains weather sensors at beaches along Chicago's Lake Michigan lakefront. These sensors generally capture the indicated measurements hourly while the sensors are in operation during the summer. During other seasons and at some other times, information from the sensors may not be available. See https://data.cityofchicago.org/id/qmqz-2xku for a dataset with similar measurements on the lake water, itself.

This dataset on which this chart depends is historical only and ends at 5/17/2024. Note that because of delayed reporting, counts from recent dates are likely to be preliminary and to increase as the Department of Public Health gets additional reports.

The Annual Appropriation Ordinance is the final City operating budget as approved by the City Council. It reflects the City’s operating budget at the beginning of the fiscal year on January 1. This dataset details the budgeted expenditures in the Ordinance and identifies them by department, appropriation account, and funding type: Local, Community Development Block Grant Program (CDBG), and other Grants. “Local” funds refer to those line items that are balanced with locally generated revenue sources, including but not limited to the Corporate Fund, Water Fund, Midway and O’Hare Airport funds, Vehicle Tax Fund, Library Fund and General Obligation Bond funds.

The Chicago Park District tests water samples at beaches along Chicago's Lake Michigan lakefront, which it tests for E. coli in order to monitor swimming safety. Multiple samples may be taken from a beach and samples may be tested by culture, DNA testing, or both.

What do these numbers mean?

The modeling prediction numbers forecast real-time Escherichia coli (E. coli) bacteria levels present in the water. The Chicago Park District (CPD) in partnership with the US Geological Survey, has developed statistical prediction models by using weather data pulled from CPD buoys (https://data.cityofchicago.org/d/qmqz-2xku) and weather stations (https://data.cityofchicago.org/d/k7hf-8y75). E. coli is an indicator species for the presence of disease-causing bacteria, viruses, and protozoans that may pose health risks to the public.

The culture based testing numbers indicate E. coli levels present in the water. This method requires 18-24 hours of processing to receive results. US Environmental Protection Agency (USEPA) recommends notifying the public when E. coli bacteria levels are above the federal water quality Beach Action Value (BAV), which is 235*CFU. When bacteria levels exceed 235 CFU, a yellow or red flag will be implemented. This standard is used at beaches throughout the Great Lakes region. For more information please refer to the USEPA Recreational Water Quality Criteria.

The rapid testing method (qPCR analysis) is a new method that measures levels of pathogenic DNA in beach water. Unlike the culture based test that requires up to 24 hours of processing, the new rapid testing method requires a few hours for results. The Chicago Park District can use results of the rapid test to notify the public when levels exceed UPEPA recommended levels. US Environmental Protection Agency (USEPA) recommends notifying the public when DNA bacteria levels are above the federal water quality Beach Action Value (BAV), which is 1000*CCE. When DNA bacteria levels exceed 1000 CCE, a yellow or red flag will be implemented. For more information please refer to the USEPA Recreational Water Quality Criteria (http://water.epa.gov/scitech/swguidance/standards/criteria/health/recreation).

* The unit of measurement for Escherichia coli is Colony Forming Units (CFU) per 100 milliliters of water.
*The unit of measuring DNA is Enterococci Calibrator Cell Equivalents (CCE) per 100 milliliters of water.

This dataset includes recommended positions and salaries for 2014 by title (without names) and salary. The dataset is excerpted from the 2014 Budget Recommendations, which is the line-item budget proposed by the Mayor to the City Council for approval. Disclaimer: the “Total Budgeted Units” column displays either A) the number of employees AND vacancies associated with a given position, or B) the number of budgeted units (ie. hours/months) for that position. “Position Control” determines whether Total Budgeted Units column will count employees and vacancies or hours/months. If a Position Control is 1, then employees and vacancies are displayed; if a Position Control is 0, then the total number of hours/months recorded is displayed. Owner: Budget and Management. Frequency: Data is updated annually. For more information about the budget process, visit the Budget Documents page: http://j.mp/lPotWf.
